Latest SPARK MAX Client - Version 2.1.1

The SPARK MAX Client will not work with SPARK MAX beta units distributed by REV to the SPARK MAX beta testers. It is only compatible with units received after 12/21/2018.

System Requirements

Windows 10 64-bit

Windows 7 64-bit might work but it is not supported.

Internet connection for automatic updates

Installation Instructions

Download the SPARK MAX Client installer above.
Run the installer. Windows may require approval to install the application.
During the installation process, separate driver installation windows may appear. Some driver installations may fail if you already have the driver installed from a previously installed Client, this is expected.
Once installed, run the application. If prompted, be sure to grant network access. Without network access, the client software won't be able to download the latest SPARK MAX firmware and client updates.

Error During First-time Firmware Update

If this is the first time installing the SPARK MAX Client or connecting a SPARK MAX in Recovery Mode, you may see an error the first time you try to update firmware on your computer. The DFU driver is one of two drivers installed by the Client and is used for updating firmware. It may not install completely until a SPARK MAX in DFU Mode (Recovery Mode) is plugged in to the computer.

If you see an error during your first firmware update, please do the following:

Close the Client application.
Unplug the SPARK MAX from the computer.
Plug the SPARK MAX back into the computer.
Open the Client application.

Alternatively, you can preemptively finalize the DFU driver installation by following the Recovery Mode steps before using the Client for the first time.

We are aware of this issue and will be releasing a fix in a future update of the SPARK MAX Client.

Troubleshooting

As we get feedback from users and identify exact causes for issues, please look back here for troubleshooting help. If you are running into issues running the SPARK MAX Client try the following BEFORE contacting support@revrobotics.com:

Try running the SPARK MAX Client as an Administrator
Make sure that Windows is fully up-to-date. Some computers have Windows Update disabled and need to be updated manually.
Check the Device Manager and verify that the SPARK MAX shows up as one of the following two devices with no caution symbols:

Normal operating mode: Device Manager -> Ports (COM & LPT) -> USB Serial Device (COMx)
Recovery mode: Device Manager -> Universal Serial Bus Controllers -> STM Device in DFU Mode

If the device shows up with errors or as STM32 BOOTLOADER, try installing the DFU drivers separately.

It is recommended to keep your SPARK MAX up-to-date with the latest firmware. The SPARK MAX Client application will automatically download the latest firmware, but you can also download the firmware manually below:

Latest Firmware - Version 1.5.2

This firmware will not work with SPARK MAX beta hardware units distributed by REV to the SPARK MAX Beta testers. It is only compatible with units received after 12/20/2018.

Latest Firmware Change Log - Version 1.5.2

Fixes issue with the kDataPortConfig parameter not enabling Alternate Encoder Mode on a power cycle after it has been configured and saved to flash.
Improves Gate Driver Fault recovery.

Previous Firmware Change Log - Version 1.5.1

Improvements to BLDC commutation timing.

Most noticeable at high RPMs only achievable by the NEO 550.

Fixes rare case where the SPARK MAX Status LED shows normal driving but no actual output is occurring until a reboot of the controller.

Previous Firmware Change Log - Version 1.5.0

Version 1.5.0 Changes

Adds a unique hash key to the firmware. This key is a hashed value based on the unique 96-bit device ID guaranteed to be unique for every STM32 device. The hash value itself is 32-bits to make transmission/reception and on-board comparison easier. It is unlikely for a key collision especially since most buses have only a small number of devices.
Adds ID Query command to have all devices which match the CAN ID sent to return their unique hash key. This is typically used to identify all devices with CAN ID 0 but can be used to identify devices with conflicting CAN IDs.
Adds ID Assign command, which sends a unique hash key and a CAN ID, which is received by any device whose CAN ID matches the ID field. The device whose unique hash matches has their own CAN ID set to the desired value. This is for initial or automatic provisioning, or to re-address devices with the same CAN ID.
Adds identify command which flashes the LED blue/magenta. This command uses the CAN ID, or the unique hash if CAN ID = 0.
Complete overhaul of USB interface, creating a generic USB-to-CAN driver connection to act as the bridge to the interface.
Adds Alternate Encoder Mode for BLDC external encoder support.
Adds device manufacturing info to firmware frame.
Adds retry frame to CAN bootloader if there is an issue.

Version 1.4.1 Changes

Fixes issue where creating a CANSparkMax object would cause the SensorType parameter to be set to NoSensor.

Previous Firmware Change Log - Version 1.4.0

Version 1.4.0 Changes

Adds non-competition heartbeat command when not used with a roboRIO.
Adds Raspbian support using official WPILib tools.
Adds locking mechanism to prevent simultaneous USB and CAN commands.
Proportional blink codes now match inversion settings (i.e. positive input is always green, and negative input is always red).
Limit switch and soft limits now follow inversion settings.
Motor controller inversion now in the firmware instead of the API.
Adds a configurable range for absolute feedback devices (currently only applicable to an absolute mode analog sensor), which also prevents users from setting a setpoint out of range.
Adds ability to use both absolute and relative analog sensors as feedback devices
Adds filtering for Analog sensor with settings for velocity moving average filter
Adds ability to configure how errors are tracked and handled by the user.

Calls can be automatically registered and tracked, with any errors displayed to the DriverStation or users can use the GetLastError() after calls to determine if an error has been thrown. This is done by changing the error timeout through SetCANTimeout(), where a timeout of 0 means that the calls are non-blocking, and errors are checked in a separate thread and sent through to the driver station.

Other minor improvements and bug fixes.

Version 1.3.0 Changes

Ability to configure the feedback device for the PIDController.
Addition of CANAnalog which will function as a possible feedback device.
Added API for using encoders with brushed DC motors.
Adds API to enable and set soft limits.
All control modes now reset integrator on limit switch activation for long as the limit switch is held.
Smart Motion now honors acceleration rate after limit switch changes from triggered to not triggered.
Fixes issue where sticky faults can be cleared incorrectly when a new fault is set and the old fault is no longer present.
Adds status 3 periodic frame for analog sensor.
Other minor improvements and bug fixes.

Version 1.2.1 Changes

Adds initial CAN bootloading functionality.

Requires continuous power during update and requires USB recovery if the update fails after erasing the flash (i.e. power is lost during update).
This is not yet integrated into a formal tool, but is exposed in the API. Future versions will allow recovery over CAN.

Fix to bus voltage measurement, previous version reported a lower value.
Additional accuracy improvements to all ADC measurements.
Adds additional filtering to bus voltage.
Fix for Follow settings not being reapplied after power cycle.
Adds ability to change units for arbFF between voltage and percent bus voltage (or percent compensated voltage).

Previous Firmware Change Log - Version 1.1.33

Fixes issue that causes a Gate Driver Fault if the NEO is spinning at a certain speed during power up.

e.g. while still moving after a breaker trips for more than ~1.4s after breaker recovery.

Fixes issue where configuration data can be corrupted under a unique set of conditions, including loss of power while configuration settings are being saved to flash memory.

Issue symptoms: Controller cannot be controlled by a normal address and would report a firmware version of 0.0.0 in the Client, even after a successful firmware update. Updating a controller that is in this state to 1.1.33 will recover the controller.

Previous Firmware Change Log - Version 1.1.31

Adds new Smart Velocity mode - uses same constrains as the Smart Motion mode but outputs velocity instead of position. This is not a motion profiling mode, but rather provides acceleration limiting as opposed to simple ramp rates.
Improvements to heartbeat implementation.
CAN ID of 0 now considered 'unconfigured' and will not be enabled.
Changes the default output range for all PID slots to be [-1,1] instead of [0,0]
Changes setpoint commands to 'stick' instead of relying on periodic frames from the controller.
Follow mode can now persists through a power-cycle.
Periodic Status 2 (position data) frame rate default changed from 50ms to 20ms.
Watchdog changed to 220ms.
Proportional blink codes while driving now have a minimum blink rate (minimum is same as 10% applied output blink rate).
Fault flag 'over voltage' replaced with 'IWDT Reset'.
Velocity and Position conversion factors are now used for all internal PID calculations.

This firmware update requires an API update. Please see the API Information section for the latest updates. The table below outlines the compatibility between firmware versions and API versions:

API
LabVIEW - 1.0.0-26 Java - 1.0.28 C++ - 1.0.27	LabVIEW - 1.1.8 Java - 1.1.8 (or newer) C++ - 1.1.8 (or newer)
Firmware	1.1.26 (or newer)	Not Compatible	Compatible
Firmware	1.0.385 (or older)	Compatible	Not Compatible

Adds ability to set the stored sensor position
Adds ability to set the maximum PID integral accumulator value to prevent integral windup
Adds ability to set the PID I accumulator value
Adds filter function to PID derivative value
Adds closed-loop current control
Adds closed-loop ramp rate separate from open-loop
Adds ability to follow Phoenix 4.11 motor controllers

Note: This feature depends on the firmware of the Phoenix controllers, and is not controlled by REV. We will do our best to build this functionality, but this is not an officially supported feature.

Adds ability to set a unit conversion for both velocity and position units
Adds ability to reset to factory defaults
Improvements to smart current limits
Improvements to current data sent over CAN

Improvements to brownout behavior.

Firmware Update Instructions

Follow the steps below to update the firmware on your SPARK MAX:

Connect your SPARK MAX Motor Controller to your computer with a USB C cable.
Open the REV SPARK MAX Client application.
The Client should automatically scan and connect to your SPARK MAX. If your SPARK MAX is running outdated firmware, you will be notified with a pop-up window like the one pictured below:
Click Open Network Tab & Scan Bus and proceed to the next step.
If your SPARK MAX is running firmware older than 1.4.0, you may not see a pop-up and will need to proceed directly to the Network tab and click Scan Bus manually. If your SPARK MAX is listed and you are unable to click the checkbox next to it, you must put your SPARK MAX into Recovery Mode.
Once in recovery mode, click Scan Bus in the Network tab and proceed on to the next step.
Your SPARK MAX should now be listed in the device list. Click the checkbox next to the SPARK MAX you wish to update, and click Load Firmware.
Select the latest firmware file in the firmware directory that the client created on startup. If there isn't a firmware directory, you can also navigate to a file that was downloaded manually. Click Open once the appropriate firmware file is selected:
Click Yes to confirm the update.
Once complete, the Client will rescan the bus and display the updated controllers.

Updating Multiple Devices with the USB-to-CAN Bridge

SPARK MAX Firmware Version 1.5.0 includes a USB-to-CAN Bridge feature that allows a single USB-connected SPARK MAX to act as a bridge to the entire CAN bus it is connected to. This allows for configuration and simultaneous updating of multiple SPARK MAX controllers without having to connect to each one individually. Using this feature requires the following:

A USB-connected SPARK MAX that is updated to firmware version 1.5.0 or newer to act as the Bridge.
Other SPARK MAXs connected on the CAN bus must be individually updated to firmware version 1.4.0 before they are able to receive mass-updates from the Bridging SPARK MAX.

Once these requirements are satisfied, navigate to the Network tab, select the controllers you wish to update, and follow the same firmware update procedure described above starting at Step 4.

When complete, the Client will display the number of successfully updated controllers.

If a controller fails to update it is usually due to the process being interrupted by a bad power or CAN connection. Severe interruptions can cause the firmware update to be corrupted. A corrupted controller can no longer be updated over the USB-to-CAN Bridge, however, it can be recovered by connecting to the controller directly over USB and putting it in Recovery Mode.

Factory Images

When updating the SPARK MAX Firmware we recommend using the SPARK MAX Client and the latest firmware file listed above. When updating normally, key configuration parameters, such as the CAN ID, will be preserved through an update, preventing the need to reconfigure every time you update. In some rare instances it may be beneficial to completely reinstall the factory firmware and reset all configuration parameters. Factory images can be found below:

Previous Firmware Change Log - Version 1.1.26 (beta)

Adds new Smart Motion mode utilizing trapezoidal motion profiling
Improvements to velocity decoding for low speeds and associated PID control loops requiring control at low speeds
Improvements to gate driver fault handling
Adds voltage compensation mode
Adds ability to set the stored sensor position
Adds ability to set the maximum PID integral accumulator value to prevent integral windup
Adds ability to set the PID I accumulator value
Adds filter function to PID derivative value
Adds closed-loop current control
Adds closed-loop ramp rate separate from open-loop
Adds ability to follow Phoenix 4.11 motor controllers

Note: This feature depends on the firmware of the Phoenix controllers, and is not controlled by REV. We will do our best to build this functionality, but this is not an officially supported feature.

Adds ability to set a unit conversion for both velocity and position units
Adds ability to reset to factory defaults
Improvements to smart current limits
Improvements to current data sent over CAN
Improvements to internal settings table implementation
Calling the constructor no longer resets the encoder count. This must be done manually by running CANEncoder.setPosition()

Previous Firmware Change Log - Version 1.0.385

Fixes PWM control issue introduced by version 1.0.384.

Previous Firmware Change Log - Version 1.0.384

Fixes GetPostition() randomly returning 0.
Fixes momentary velocity spike when accelerating from 0 speed.
Fixes issue related to rapid control mode switching by the user.
Fixes issue related to extreme low voltage CAN bus operation.
Adds conversion for motor temperature.
Improvement to 'Has Reset' flag.
Improvements to brownout fault indicator.
Improvements to brownout behavior.

Firmware Update Instructions

Follow the steps below to update the firmware on your SPARK MAX:

Connect your SPARK MAX Motor Controller to your computer with a USB C cable.
Open the REV SPARK MAX Client application.
The Client should automatically scan and connect to your SPARK MAX. If your SPARK MAX is running outdated firmware, you will be notified with a pop-up window like the one pictured below:
Click Open Network Tab & Scan Bus and proceed to the next step.
If your SPARK MAX is running firmware older than 1.4.0, you may not see a pop-up and will need to proceed directly to the Network tab and click Scan Bus manually. If your SPARK MAX is listed and you are unable to click the checkbox next to it, you must put your SPARK MAX into Recovery Mode.
Once in recovery mode, click Scan Bus in the Network tab and proceed on to the next step.
Your SPARK MAX should now be listed in the device list. Click the checkbox next to the SPARK MAX you wish to update, and click Load Firmware.
Select the latest firmware file in the firmware directory that the client created on startup. If there isn't a firmware directory, you can also navigate to a file that was downloaded manually. Click Open once the appropriate firmware file is selected:
Click Yes to confirm the update.
Once complete, the Client will rescan the bus and display the updated controllers.

Updating Multiple Devices with the USB-to-CAN Bridge

A USB-connected SPARK MAX that is updated to firmware version 1.5.0 or newer to act as the Bridge.
Other SPARK MAXs connected on the CAN bus must be individually updated to firmware version 1.4.0 before they are able to receive mass-updates from the Bridging SPARK MAX.

Once these requirements are satisfied, navigate to the Network tab, select the controllers you wish to update, and follow the same firmware update procedure described above starting at Step 4.

When complete, the Client will display the number of successfully updated controllers.

Factory Images

Below you will find information on how to download and install the SPARK MAX APIs for LabVIEW, Java, and C++.

Current API version by Language
LabVIEW	1.5.2
Java	1.5.2
C++	1.5.2

Latest API Change Log - Version 1.5.2 - Java/C++ Only

Fixes possible crash when no CAN bus connected when code is first run.
Adds the CAN ID of the device to every error message.
Reduces the timing for error messages, and removes repeated messages to make error diagnostics more clear.
Makes the base class rev::CANSensor object public to help with some Kotlin wrappers.
Sends an error to the console if two CANSparkMax objects are created with the same CAN ID.

Latest API Change Log - Version 1.5.2 - LabVIEW Only

Fixes issue with Follow.vi not deploying correctly.

Previous API Change Log - Version 1.5.1 - Java/C++

Updated dependencies for WPILib 2020.1.2
Removed extra thread for setpoint calls.

Set calls now directly call CAN, reducing CAN latency.

Adds SetVoltage() override for the WPILib SpeedController class.

Previous API Change Log - Version 1.5.1 - LabVIEW

Update to LabVIEW 2019 (FRC 2020)

Previous API Change Log - Version 1.5.0 - All Languages

Adds the ability to use an alternate encoder as a feedback device when connected to the SPARK MAX Data Port. When using an alternate encoder, Hard Limit Switches cannot be used on that SPARK MAX.
Adds the ability to send telemetry data back from a SPARK MAX. This is done by opening a Telemetry Stream for a particular subset of telemetry data (categorized by TelemetryIDs). A TelemetryMessage contains the ID, value, timestamp, name, units, and bounds of a particular TelemetryID. Additionally, users can list what subset of telemetry data is available for each SPARK MAX.
Adds a DeviceScanner that will scan the CANBus for other CAN Devices. Will filter what devices to look for, and users can specify filters to let through different devices.
Addresses bug with CANEncoder backwards compatibility.
Addresses bug with the Java Control Frame Period not being properly set.
