You can develop for STM32 using the Arduino IDE. Here are the steps: What you need: STM32F103C8T6 module (ARM32 Cortex-M3, 72 Mhz, 64K flash, 20K SRAM, 33 I/O pins, 3.3V), you can find cheap modules on eBay Serial-to-USB-module (3.3V level, e.g. CH340) Steps: 1. Wire STM32 module and Serial-to-USB module as shown below:        2. … Continue reading Arduino goes STM32
