Andrew Tridgell 30e4323c6d HAL_ChibiOS: disable USART1 till USB problem solved
using USART1 causes USB disconnects. The behaviour is like CTS/RTS is
enabled on USART1, but it is disabled.

this uses DMA bounce buffers for bus transfers, and falls back to CCM
ram in allocations if the type is unspecified
2018-01-15 11:46:02 +11:00
Andrew Tridgell 36227aa126 HAL_ChibiOS: implement bus speed and smbus for I2C
use the slowest speed of all devices on the bus
2018-01-15 11:46:02 +11:00
Andrew Tridgell 4b5e617673 HAL_ChibiOS: added missing DMA table for STM32F405 2018-01-15 11:46:02 +11:00

Andrew Tridgell 755eca31c2 HAL_Chibios: don't unregister shared DMA
the shared DMA handle is a property of the bus, not the device, so
should not be unregistered when the device is removed

Andrew Tridgell 9812fc9574 HAL_Chibios: prevent creation of i2c devices on invalid bus 2018-01-15 11:46:02 +11:00
Andrew Tridgell b62773bbad HAL_ChibiOS: improved auto-config of ADC pins
ADC config now based on pin_scaling array
2018-01-15 11:46:02 +11:00
Andrew Tridgell 1cc4b92b76 HAL_ChibiOS: added additional FMUv3 analog pins 2018-01-15 11:46:02 +11:00
Andrew Tridgell aa2175ec0c HAL_ChibiOS: show ADC1 channels in hwdef.h 2018-01-15 11:46:02 +11:00
Andrew Tridgell 5a7e2f75d1 HAL_ChibiOS: added ADC1_Map to STM32 tables 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 b57f8f01c6 HAL_Chibios: fixed return for read on invalid gpio pin 2018-01-15 11:46:02 +11:00
Andrew Tridgell 7971f03bde Hal_Chibios: fixed F412 SPI config 2018-01-15 11:46:02 +11:00
Andrew Tridgell 21f40da510 HAL_Chibios: align GPIO pins with px4 build 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 c742543565 HAL_Chibios: align SPI device IDs with px4 IDs
this makes for easier update to ChibiOS without redoing accelcal
2018-01-15 11:46:02 +11:00
Andrew Tridgell 6dbab450a5 Hal_Chibios: use AP_BoardConfig::io_enabled() 2018-01-15 11:46:02 +11:00
