* Add STM32F103 portGrigori Goronzy2018-04-09164-0/+266623
| | | | | | | | | | | | Add a fully functional STM32F1 port, currently mostly targeting STM32F103 microcontrollers. This requires an 8 MHz XTAL. The maximum possible step rate is around 282K steps per second. This uses stm32flash to burn the firmware. The bootloader needs to be started by setting BOOT0 to 1 and resetting the MCU. There is no automatic bootloader, unlike on Arduino. Signed-off-by: Grigori Goronzy <greg@kinoho.net>
* sched: Introduce sched_wake_tasks() function to wake up tasksKevin O'Connor2017-08-083-6/+49
