This is first part of new softserial code. Main timer code is changed, changes to rest of code are kept to minimum.
macros for BASEPRI based synchronization are added to project (atomic.h)
TIMER_PERIOD fixed in pwm_rx.c
All msp ports are now re-initialised when disarming.
Bug wa introduced by c06fd78b83 - see
#144.
Runtime serial port scenario should not have been erased.
Fixes#144 and #155. Cleanup #125.
- NVIC priorities are moved to separate file, all values are replaced wit symbolic names. Priorities should be the same.
- tiny change in DMA initialization
This has highlighted that the existing codebase is quite targeted
towards systems that use USART1 and 2. Annoyingly the inverter is on
USART1 and the sbus code requires callbacks so still won't work yet.
