Andrew Tridgell 6fb84cfa6b HAL_ChibiOS: support microSD slowdown 
allow use of BRD_SD_SLOWDOWN to slow down clock on microSD
 2019-01-11 09:48:16 +09:00
Andrew Tridgell 97dae1a03d HAL_ChibiOS: update to match plane 3.9.0beta6 2018-08-02 12:38:27 +09:00
Andrew Tridgell 0a5d287326 HAL_ChibiOS: support uartG 2018-06-29 08:17:38 +10:00
Andrew Tridgell 369ac5edd0 HAL_ChibiOS: save more space in the bootloader 2018-06-25 21:22:31 +10:00
Alexander Malishev 6b15b2f44f HAL_ChibiOS: Enable sdcard on spi bus 2018-05-27 19:10:24 +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 01e9c55721 HAL_ChibiOS: fixed SPI bus speed on SPI3 
and add optional bootup test of SPI bus speeds to help with porting to
new MCUs
 2018-04-07 09:10:29 +10:00
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

Andrew Tridgell 427e00dd41 HAL_ChibiOS: switched to system timer for AP_HAL::micros() 
this uses the ChibiOS system timer instead of a separate GPT timer for
the core ChibiOS timer. The advantage is it saves us a timer, plus it
changes ChibiOS to use a 1MHz clock on its timer, which gives us
higher resolution for delays.

This has a remarkable effect on timing jitter, reducing it greatly

Andrew Tridgell b7c4dea9d3 HAL_ChibiOS: gain back 250usec in loop time 
if we have already called delay_microseconds_boost() then we know
we've given up time to drivers, so we can avoid the extra delay in the
HAL

Andrew Tridgell aee6462deb HAL_ChibiOS: enable I2C clearing on F412 board only 
may be needed on other boards in the future, but for now we only know
its needed on an I2C 20789, which is rare
 2018-02-08 17:36:33 +11:00
Siddharth Purohit 40142e5aef ChibiOS: implement way to clear i2c bus by toggling clock line 2018-02-08 17:36:33 +11:00
Andrew Tridgell 23555f4c25 HAL_ChibiOS: allow for empty storage during bringup 
useful when storage backend driver isn't written yet
 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 468cadca45 HAL_ChibiOS: auto-generate UART driver declarations 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
bugobliterator 5feef04f5f HAL_ChibiOS: add support for CCM memory 
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 26d6947bf6 HAL_ChibiOS: fixed PWM output 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
