v1.7.4 Firmware + GUI

Note:
You must manually run full calibration once after changing TMC board or encoder to calibrate the ADC and encoder settings with power!

General changes:

• F407 reboots correctly after exiting DFU bootloader
• Added I2C helper classes and support for PCF8574 button sources
• More efficient task activation using notifications instead of semaphores where possible
• Fixed hex parsing in commands (xFF equivalent to 255 shortening commands for very long values)
• Option to forward SPI encoders to TMC for commutation or combining TMC and axis position sources
• Improved linux compatibility
• Fixed effect envelope handling
• Updated to tinyusb 0.13
• Reports 64 buttons in descriptor

Changes for TMC:

• TMC saves ADC offsets in flash and checks if they are valid
• TMC calibration sequence to measure adc offsets and encoder settings
• Partial rewrite of encoder alignment routines minimizing movement
• Automatic index search and position offset reloading for TMC w. ABN encoders (Autohoming for wheels)
• Flux reported in current readout
• Experimental external encoder support for tmc (no absolute encoder benefits yet but possible to add)
• Faster startup
• Allowed combining TMC encoder for commutation and externally in axis selected encoder for gamepad positioning for higher precision in gamepad and better speed for commutation

v1.6.2 Firmware + GUI

Changes:

• Additional buffer checks for command interfaces
• Improves stability of HID command interface while broadcasting changes
• Reset to factory defaults/erasing flash if major version differs or flash seems locked (experimental. might fix writing issues)
• Smaller bug fixes regarding odrive & vesc & encoders

v1.6.0 Firmware + GUI

Changes since last release:

VESC CAN id selection added

GUI updated to Qt6
pyqtgraph replaced with Qt-Charts

v1.5.2 Firmware + GUI

Warning: New command system and syntax. MUST update GUI in order to use this firmware

From this version on the firmware can be fully controlled via HID.

Commands can be sent via UART with a 500000 baud on the primary uart.
In the F407 version this is enabled by default but it will not broadcast on this interface to limit the rate.
CDC and HID will broadcast changes as read value replies.

Changes:

• Completely new command system
• Stability improvements for communication
• Classes and instances if multiple are active are addressed directly instead of requiring globally unique command names
• Support for HID commands with new reports
• Effect tuning
• Removed old HID handler and reports
• Experimental support for commands via UART
• Removed separate normalized axis class
• MT6825 encoder support
• Experimental speed limiter available via commands
• TMC hardware type selection for features and scaling of constants
• Unique command handler ID assigned for every instance
• Larger FreeRTOS heap
• Updated HAL
• Commands can be locked behind a debug mode to prevent accidential dangerous settings
• ODrive connection detection
• Many bug fixes.....
