Andrew Tridgell	765e00faf1	HAL_ChibiOS: reduce memory used by serial buffers ... this does not appear to affect log download speed. It saves about 27k of memory	2018-08-16 17:01:01 +10:00
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	2018-02-14 18:27:00 +11:00
Andrew Tridgell	daa9eec836	HAL_ChibiOS: auto-configure timer channels ... allow for one marked PPMIN for input	2018-01-15 11:46:02 +11:00
Andrew Tridgell	d65ec2ada7	HAL_ChibiOS: moved more headers to common ... allow customisation, but don't require every port to copy the defaults	2018-01-15 11:46:02 +11:00
