Firmware revision 11

• Stall protection
• 15/16 degree timing resolution
• Configurable analog throttle setpoints
• Default duty_spup is reverted back to 15 with maximum capped removed
• Symmetric duty_rate

Changes to configuration parameters:

• timing is now in 15/16 (0.9375) degree increments (in order to convert an old value to a new value, multiply by 4)

Firmware revision 10

Technical release that brings improvements for high RPM applications, temperature protection improvements, minor bug fixes and support for STM32G431 MCUs.

Firmware revision 9

• New native bidirectional serial protocol
• Support for SBUS2/CRSF input and telemetry
• Support for multiple ESCs on iBUS telemetry bus via telem_chid
• Require power cycle for telem_mode to take effect
• Engage drag brake only after rotor has stopped
• Take lowest ramp point from duty_spup rather than fixed 25%
• Maximum duty_spup is 50 (was 25)
• Default duty_drag is 0 (was 75)

Bootloader revision 2 (patch 1)

• PA2 pass control faster on invalid signal

Firmware revision 8

• Music format extensions to better accommodate for RTTTL
• Fix bug when watchdog reset was delayed while playing music
• Fix brushed mode (broken in Rev7)
• Require power cycling for brushed mode

Firmware revision 7

• Maximum duty cycle ramp
• Fixed throttle mode

Changes to configuration parameters:

• duty_ramp is now maximum duty cycle RPM-based ramp
• duty_rate is now acceleration slew rate (formerly duty_ramp)

Changes to DSHOT commands:

• Command 42 now selects maximum duty cycle ramp value in tens of kERPM
• Commands 43/44 increase/decrease acceleration slew rate
