Andrew Tridgell c6879c679a HAL_ChibiOS: re-enable USART1 on revo-mini 2018-02-14 18:27:00 +11:00
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

Andrew Tridgell 30e4323c6d HAL_ChibiOS: disable USART1 till USB problem solved 
using USART1 causes USB disconnects. The behaviour is like CTS/RTS is
enabled on USART1, but it is disabled.
