Pneumatic Hub Firmware Changelog

  • Fixes USB compatibility for Mac

  • Fixes bug preventing updating downstream SPARK devices

  • Improves performance of USB bridging

Fixes bug preventing proper communication with downstream SPARKs

  • Updates the bootloader. This update must be done via DFU.

  • Switches the USB CAN bridging to use SLCan

    • Note: Devices that use SLCan are NOT compatible with REV Hardware Client when used over USB. Devices running v26.x.x+ can only be used via REVUI, or downstream of a REV CAN device running v25.x.x or lower with RHC.

    • Fixes issue where compressor channel does not turn on after updating to v23.0.0 without explicitly setting a compressor mode

    • Improves device brownout detection

    • Improves CAN fault detection

    • Improves robustness against soft-bricking

    • Reduces stutters in compressor and solenoids with high CAN utilization

    • Allows compressor test mode for the pressure relief valve without having to send a solenoid command first

    • Disallows actuation from REV Hardware Client if roboRIO was previously connected

    • Improves over current protection for larger compressors

    • Improves accuracy of various readings:

      • Analog sensor voltage

      • Battery voltage

      • Compressor current

    • Improves performance for larger compressors

    • Improves hardware fault reporting

    • Adds compressor test mode for the pressure relief valve which is activated via holding the MODE button for 7 seconds

    • Blinks the status LED blue when sticky faults are successfully cleared via the MODE button

    • Blinks the status LED orange and green when the compressor is over current

    • Fixes issue where the device would hang after receiving a malformed CAN frame

    • Fixes certain faults that were incorrectly triggered when the device was only powered via USB

    • Persists sticky faults across power cycles

    • Allows sticky faults to be cleared by holding down the device's button

    • Updates LED patterns

    • Improves accuracy when using the analog sensor to control the compressor
