From 75d57372115eb70ac22d16240c5c887df8ae1da8 Mon Sep 17 00:00:00 2001 From: Grigori Goronzy Date: Sat, 31 Mar 2018 15:34:59 +0200 Subject: Add STM32F103 port 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.
