this allows for hwdef.dat lines like this:
PA8 MCO1 RCC
PC9 MCO2 RCC
you can control the scaling by defining the following:
- STM32_MCO1SEL
- STM32_MCO1PRE_VALUE
- STM32_MCO2SEL
- STM32_MCO2PRE_VALUE
not included in production versions, and baro is not generally a good
idea on a GPS due to impact of airflow
also disable unused IMU, SPI bus and 2nd I2C and re-enable 2nd CAN as
helical units have dual CAN
if Periph panics before we mark the scheduler as initialised then we don't watchdog, which we really need to do on periph nodes so they can be re-flashed conveniently.
add support for undef of STM32 lines and DMA_NOMAP
add support for F103 running at 24Mhz
add f103 variants of iofirmware
reduce memory usage in iomcu for new model
correct pwm output reporting
split iofirmware into config + mcu to allow f103 definition
don't enable non-existant timers on F103
enable TIM4 in shared mode on IOMCU for dshot
stop the PWM peripheral in rcout DMA swapping on IOMCU to prevent UART corruption
provide debugging options on iomcu dshot
support unshared DMA with iomcu dshot
optimize rcout on iomcu
tune iomcu stack for 8 channels
set timer counter size to be a byte wide
use HAL_DSHOT_ENABLED instead of DISABLE_DSHOT
build iomcu-dshot from existing iomcu
correct defines for DMAR size on iomcu
allow iomcu dshot rate to be configured from FMU
correct DMA allocation for dshot on iomcu
allow debug builds on iofirmware
ensure dshot is enabled on iomcu dshot
support proper iomcu dshot output thread triggered by FMU
allow selective disablement of serial LEDs and passthrough
disable serial LEDs and passthrough on iomcu-dshot
propagate ESC telemetry to iomcu
dshot_send_groups() for iomcu
remove use of ICU on iomcu for dshot. only allocate possible DMA channels
rename serial passthrough and dshot defines
update dshot docs
resize dshot iomcu main stack to minimum
correct dshot prescaler usage and bit_width_mul calculation
use ChibiOS in tickless mode on iomcu-dshot so that virtual timers can be used
propagate dshot commands to iomcu
passthrough oneshot125 to iomcu
