Overhauls the DShot driver with per-timer BDShot selection, multi-timer
sequential capture, Extended DShot Telemetry (EDT), and AM32 ESC EEPROM
read/write via MAVLink. Expands ESC support from 8 to 12 channels.
BDShot:
- Per-timer BDShot protocol selection via actuator config UI
- Multi-timer sequential burst/capture on any DMA-capable timer
- Adaptive per-channel GCR bitstream decoding
- Per-channel online/offline detection with hysteresis
Extended DShot Telemetry (EDT):
- Temperature, voltage, current from BDShot frames (no serial wire)
- New DSHOT_BIDIR_EDT parameter
- EDT data merged with serial telemetry when both available
AM32 EEPROM:
- Read/write AM32 ESC settings via MAVLink ESC_EEPROM message
- ESCSettingsInterface abstraction for future ESC firmware types
- New DSHOT_ESC_TYPE parameter
Other changes:
- Per-motor pole count params DSHOT_MOT_POL1–12 (replaces MOT_POLE_COUNT)
- EscStatus/EscReport expanded to 12 ESCs with uint16 bitmasks
- Numerous bounds-check, overflow, and concurrency fixes
- Updated DShot documentation
I don't think we have a way to explicitly detect if BAT1 or BAT2
"bricks" are correct, so we have to assume they are, and rely on the
voltage/current shown.
Additionally, we can now power cycle sensor power.
* hrt: Fix PPM input on channel 2
The CCMR1_PPM define for PPM input on channel 2 was incorrectly set to 2,
which was setting bits for channel 1 instead of channel 2. This prevented
PPM input from functioning properly on channel 2.
Changed CCMR1_PPM for channel 2 from 2 to (1 << 8), which correctly
configures the CC2S bits for input capture mode on TI2.
This fixes an issue noted in the existing code comment:
"FIXME! There is an interaction in the CCMR registers that prevents
using Chan 1 as the timer and chan 2 as the PPM"
Tested on STM32H743 with PPM input on PC7 (TIM8_CH2).
* rc_input: enable sharing serial and PPM pin
By setting RC_SERIAL_PORT_SHARED_PPM_PIN_GPIO_RX it is now possible to
use the same pin on the STM32 for PPM input as well as serial input.
* boards: Add support for Holybro KakuteH7-Wing
