Andrew Tridgell	c12d14d7a4	HAL_ChibiOS: check for ChibiOS features	2018-06-22 08:00:31 +10:00
Andrew Tridgell	e3b68876a9	HAL_ChibiOS: fixed tx_len on tx DMA timeout	2018-06-19 09:08:45 +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!	2018-04-07 09:10:29 +10:00
Andrew Tridgell	a86e85c6b2	HAL_ChibiOS: enable checking for DMA contention	2018-04-07 09:10:29 +10:00
Andrew Tridgell	91c741ef07	HAL_ChibiOS: use a non-blocking lock for UART shared DMA ... we can have multiple UARTs on the same thread sharing the same DMA TX channel. That can lead to deadlock with blocking locks on DMA. This makes UART requests for DMA locks non-blocking to fix the issue	2018-03-02 21:39:38 +11:00
Andrew Tridgell	875008f2a6	HAL_ChibiOS: lock all DMA channels on reboot ... this fixes a problem with the ICM-20789 on I2C where a reboot while the bus is active leaves the IMU in a dead state where it can't be recovered without a power cycle.	2018-02-08 17:36:33 +11:00
Andrew Tridgell	41758348e5	HAL_ChibiOS: added checking of lock state in shared_dma ... and use lock around check for tx completion in UART handler	2018-02-07 20:33:45 +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	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	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	2018-01-15 11:46:02 +11:00
