Andrew Tridgell 4f9bd50038 HAL_ChibiOS: implement I2C bus masks 2018-07-10 15:39:47 +10:00
Andrew Tridgell a945c97ec6 HAL_ChibiOS: fixed 3-way DMA sharing bug 
when we have 3 way contention across two DMA streams we could get the
dma_deallocate function called in an object from two places at
once. This adds a mutex that prevents that scenario

mirkix c2eee2db23 AP_HAL_ChibiOS: add STM32F7 I2C support 2018-04-29 07:59:52 +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 9ab695b7ca HAL_ChibiOS: fixed namespace error 
thanks to Peter for noticing

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

Siddharth Purohit 40142e5aef ChibiOS: implement way to clear i2c bus by toggling clock line 2018-02-08 17:36:33 +11:00
Andrew Tridgell 23e1b2e271 HAL_ChibiOS: added paranoid state checking on I2C 
this is here just while debugging an issue with Mark

Andrew Tridgell 87389e0fdc HAL_ChibiOS: fixed double DMA allocation on i2c 2018-02-07 20:33:45 +11:00
Andrew Tridgell 36227aa126 HAL_ChibiOS: implement bus speed and smbus for I2C 
use the slowest speed of all devices on the bus

Andrew Tridgell 8b6bab7b17 HAL_Chibios: added ChibiOS HAL 
this is based on initial work by Sid, reset here for easier merging
