Andrew Tridgell	f732a482fe	HAL_ChibiOS: support wider range of clock frequencies	5 years ago
Andrew Tridgell	4f429e6c5a	HAL_ChibiOS: fixed handling of 16bit timer wrap this fixes #12948	5 years ago
Andrew Tridgell	4674a1c68d	HAL_ChibiOS: fixed system time for clocks other than 1MHz needed for IOMCU	6 years ago
Andrew Tridgell	33076be585	HAL_ChibiOS: fixed handling of 16 bit timers when we have a 16 bit timer then systime_t is 16 bit, and we need to handle wrap of get_systime_us32()	7 years ago
Andrew Tridgell	385f735799	HAL_ChibiOS: avoid 64 bit maths in AP_HAL::micros() this saves a few cycles	7 years ago
Siddharth Purohit	395c48933c	HAL_ChibiOS: move tto using updated time conversion API	7 years ago
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	7 years ago
Andrew Tridgell	8b6bab7b17	HAL_Chibios: added ChibiOS HAL this is based on initial work by Sid, reset here for easier merging	7 years ago
