Andrew Tridgell 71cd58cc7e HAL_ChibiOS: run rc serial thread at top priority 
this maximises reliability for serial IO to ESCs, increasing flashing
reliability

Andrew Tridgell 3cd4f2a002 AP_ChibiOS: handle oneshot125 separately 
this sets up oneshot125 with the full 1000 steps of throttle
resolution, using a 8MHz clock. This matches the behaviour of modern
ESCs that measure PWM values with high accuracy

Andrew Tridgell 8e59f6aad6 HAL_ChibiOS: implement get_esc_scaling() 2018-04-07 09:10:29 +10:00
Andrew Tridgell 6fd0af11ef HAL_ChibiOS: implement telem request API 2018-04-07 09:10:29 +10:00
Andrew Tridgell 6bdb523630 HAL_ChibiOS: guarantee 1kHz output for DShot 2018-04-07 09:10:29 +10:00
Andrew Tridgell 382772d999 HAL_ChibiOS: initial support for ESC serial output 2018-04-07 09:10:29 +10:00
Andrew Tridgell 26d279e165 HAL_ChibiOS: improve DShot timing accuracy 2018-04-07 09:10:29 +10:00
Andrew Tridgell bc32276966 HAL_ChibiOS: support DShot output 
use DMAR burst DMA to minimise number of DMA channels needed

thanks to betaflight for the great reference implementation!

Andrew Tridgell 306d35655e HAL_ChibiOS: allow for bare board builds 
this allows for a build with no UARTs, no SPI, no I2C, no PWM. Great
for initial board bringup with just USB
 2018-03-02 12:52:50 +11:00
Andrew Tridgell 0cf104f2f3 HAL_ChibiOS: added scale_esc_to_unity() 
needed for per-motor compass cal
 2018-03-02 12:52:50 +11:00
Andrew Tridgell 7c23e33775 HAL_Chibios: set min output rate for oneshot to 100Hz 
this will keep ESCs happy during gyro cal
 2018-01-20 17:40:07 +11:00
Andrew Tridgell 880a84294e HAL_ChibiOS: support oneshot mode 
supports oneshot 125 and oneshot
 2018-01-20 17:40:07 +11:00
Andrew Tridgell f14a847b97 HAL_ChibiOS: rename classes to remove 'Chibi' 
it is redundent as all classes are in ChibiOS namespace, and makes the
code harder to read
 2018-01-15 11:46:02 +11:00
Andrew Tridgell 25b68dc150 HAL_ChibiOS: switch base freq when needed 
timers can't do below 123 Hz with a clock of 8MHz, so we need to
change clock frequency based on the target period
 2018-01-15 11:46:02 +11:00
Andrew Tridgell d17e9f321a HAL_ChibOS: fixed mixture of brushed and normal PWM 
allow non-brushed PWM servos with brushed main motors
 2018-01-15 11:46:02 +11:00
Andrew Tridgell c639708e22 HAL_ChibOS: auto-generate full PWM config 
use PWM markers in hwdef.dat to mark each PWM channel
 2018-01-15 11:46:02 +11:00
Andrew Tridgell 3a004adbd4 HAL_Chibios: use macro for NUM_GROUPS 2018-01-15 11:46:02 +11:00
Andrew Tridgell 26d6947bf6 HAL_ChibiOS: fixed PWM output 2018-01-15 11:46:02 +11:00
Andrew Tridgell 8b6bab7b17 HAL_Chibios: added ChibiOS HAL 
this is based on initial work by Sid, reset here for easier merging
