Andy Piper f6b1e15b0e AP_HAL_ChibiOS: optimize bdshot ISRs 2021-04-06 10:24:04 +10:00
Andy Piper 74d4af9ac9 AP_HAL_ChibiOS: reset bdshot IC correctly
don't allow dshot rates below 800Hz.
set pin speed to MID1 to avoid glitching
don't run receive pulses on a timer
2021-04-06 10:24:04 +10:00
Andy Piper 477ff72214 AP_HAL_ChibiOS: allow dshot rate to be set so as to both regularize the output as well as
allow faster rates synchronized to the loop rate
synchronize 1Khz and use Betaflight definition for prescaler
adjust dshot bitrates
don't allocate IC DMA if already allocated
cancel DMA pulses correctly
try really hard to align pulses with push() by making each dshot pulse event driven

Andy Piper f9c5f9be00 AP_HAL_ChibiOS: make dshot DMA unlock event driven in order to allow unlocking from rcout thread
refactor rcout into separate thread and process all dshot requests there
move uart DMA completion to event model
process dshot locks in strick reverse order when unlocking
convert Shared_DMA to use mutexes
move UART transmit to a thread-per-uart
do blocking UART DMA transactions
do blocking dshot DMA transactions
trim stack sizes
cancel dma transactions on dshot when timeout occurs
support contention stats on blocking locking
move thread supression into chibios_hwdef.py

separate UART initialisation into two halves
cleanup UART transaction timeouts
add @SYS/uarts.txt
move half-duplex handling to TX thread
correct thread statistics after use of ExpandingString
set unbuffered TX thread priority owner + 1
correctly unlock serial_led_send()
don't share IMU RX on KakuteF7Mini
observe dshot pulse time more accurately.
set TRBUFF bit for UART DMA transfers
deal with UART DMA timeouts correctly
don't deadlock on reverse ordered DMA locks
change PORT_INT_REQUIRED_STACK to 128

Andy Piper 3a9107245c AP_HAL_ChibiOS: allocate DMA and LED buffers correctly when the length changes
calculate DMAR pulse times correctly
ensure 50us pulse separation for LED
make sure the LEDs are signalled for output
only allow LED length to be set once

Andy Piper 401e5c2073 AP_HAL_ChibiOS: add support for bidir DShot support in RCOutput
add support for sampling GPIO pins using timer
don't restart pwm group when not doing bi-dir
fix hwdef generation preproc for TIM DMA
decode telemetry at the start of the dshot cycle
calculate dshot pulse separation correctly and ensure we output rapidly enough
calculate dshot min periods and timeouts correctly
refactor dshot_send() into dshot_send_groups()
use bi-dir dshot channel mask
selectively enable bi-dir RC Channels
