 2018-08-28 08:50:50 +10:00
Francisco Ferreira 1b46104a98 AP_HAL_ChibiOS: fix warning when STDOUT is defined 
../../libraries/AP_HAL_ChibiOS/UARTDriver.cpp:118:12: warning: 'int hal_console_vprintf(const char*, va_list)' defined but not used [-Wunused-function]

            ^
 2018-08-14 10:17:38 +10:00

of memory
 2018-08-01 13:11:16 +10:00
Andrew Tridgell 83f38d536e HAL_ChibiOS: fixed flow control auto-detect without DMA

for TX
 2018-07-13 07:34:30 +10:00

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

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

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
 2018-04-12 11:50:44 +10:00
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!
 2018-04-07 09:10:29 +10:00
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 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

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
