Andrew Tridgell e3b68876a9 HAL_ChibiOS: fixed tx_len on tx DMA timeout 2018-06-19 09:08:45 +10:00
Andrew Tridgell 8431a677d9 HAL_ChibiOS: added a timeout to DMA UART TX
this prevents a shared DMA channel being held for a long time if a CTS
pin is held either by not being connected or by a radio
2018-06-19 09:08:45 +10:00
Andrew Tridgell 2493cdbcb6 HAL_ChibiOS: switch to new bouncebuffer system
this removes the dma_flush and dma_invalidate methods and uses a
common bouncebuffer system for all CPU types. This enables microSD
support on STM32F7
2018-06-06 07:15:41 +10:00
Andrew Tridgell 0fade4eb9e HAL_ChibiOS: make sure the UART bounce buffers are DMA safe 2018-06-06 07:15:41 +10:00
Andrew Tridgell edb831653f HAL_ChibiOS: added dma_flush and dma_invalidate operations
these are needed to manage the data cache on the STM32F7
2018-06-06 07:15:41 +10:00
Andrew Tridgell 7b720aae46 HAL_ChibiOS: allow printf() to work on systems without debug console
map to hal.console once initialised
2018-05-26 19:06:25 +10:00
Andrew Tridgell 89898bae1d HAL_ChibiOS: take account of available bytes in receive_time_constraint_us 2018-05-21 14:53:18 +10:00
Andrew Tridgell 7005383f82 HAL_ChibiOS: implement uart receive timestamp API 2018-05-16 18:49:22 +10:00
mirkix cb50639e27 AP_HAL_ChibiOS: add STM32F7 UART support 2018-05-15 07:23:56 +10:00
Andrew Tridgell 5854ccbb4c HAL_ChibiOS: removed stray debug code
thanks to @alielectric for noticing
2018-05-03 17:04:14 +10:00
Andrew Tridgell e4ce2f532b HAL_ChibiOS: make smaller builds possible
this allows for much smaller builds when you disable a lot of
options. This is part of an effort to create a bootloader of less than
16k using ChibiOS

Andrew Tridgell e448b5d069 HAL_ChibiOS: implement UART port locking 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 a64819cbf2 HAL_ChibiOS: minimise DMA TX latency on contended UARTs
try to prevent long delays on other users of a DMA channel
2018-04-07 09:10:29 +10:00
Andrew Tridgell 556f3ba53f HAL_ChibiOS: make UARTs non-blocking by default
we never want blocking ports any more with ArduPilot, so defaulting to
blocking makes no sense
2018-03-02 21:39:38 +11:00
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 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 d0eb2970c7 HAL_ChibiOS: ensure RTS and CTS are both disabled for no flow control 2018-02-07 20:33:45 +11:00
Andrew Tridgell 82f1f462ae HAL_ChibiOS: ensure we don't init a uart driver twice 2018-02-07 20:33:45 +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 dce4c90467 HAL_ChibiOS: moved UART thread to UART driver
use an event model for triggering sends from tx complete DMA handler
for unbuffered uarts
2018-02-07 20:33:45 +11:00
Andrew Tridgell 4d018cf5e2 HAL_ChibiOS: take lock on DMA allocate/deallocate
this is required for the stm32_dma_stream bitmask manipulation
2018-02-07 20:33:45 +11:00
Andrew Tridgell e002fbdb8d HAL_ChibiOS: fixed a build warning 2018-02-07 20:33:45 +11:00
Andrew Tridgell 85acbcb21d HAL_ChibiOS: fixed UART send from TX complete IRQ 2018-02-07 20:33:45 +11:00
Andrew Tridgell 979a2a4796 HAL_ChibiOS: removed debug code 2018-02-07 20:33:45 +11:00
Siddharth Purohit 538af2a58a HAL_ChibiOS: fix parity and stop bit setting 2018-02-07 20:33:45 +11:00
Siddharth Purohit df4bf7e476 HAL_ChibiOS: fix irq clash with unnecessary access to readbuf ring buffer 2018-02-07 20:33:45 +11:00
Siddharth Purohit 02696882e9 HAL_ChibiOS: if unbuffered write, do continue to invoke DMA writes
adds higher latency to device sharing DMA
2018-02-07 20:33:45 +11:00
Andrew Tridgell 3dacbd1b36 HAL_ChibiOS: hold write lock for unbuffered writes 2018-02-07 20:33:45 +11:00
Andrew Tridgell ad26ca4a27 HAL_ChibiOS: implement parity and stop bits controls 2018-02-07 20:33:45 +11:00
Andrew Tridgell 2e15285c51 HAL_ChibiOS: refuse unbuffered writes without DMA
we would need much more complex code to handle this
2018-02-07 20:33:45 +11:00
Andrew Tridgell 3f2cc2c9d6 HAL_ChibiOS: implement low latency UART writes
this implements the set_unbuffered_writes() API by performing writes
directly in the write() call and not from a timer
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 d1f93cd66c HAL_Chibios: auto-generate I2C, SPI and UART device lists
this is less error prone and make a port faster as more information is
in hwdef.dat
2018-01-15 11:46:02 +11:00
Andrew Tridgell 280140bf25 HAL_ChibiOS: added support for MindPX-v2 2018-01-15 11:46:02 +11:00
Andrew Tridgell 41be81af34 HAL_Chibios: added hardware flow control for UARTs
implement RTS in software and CTS in hardware
2018-01-15 11:46:02 +11:00
Andrew Tridgell c3435e45c5 HAL_ChibiOS: initial port to FMUv4 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
