STM32F0 under Linux — Tutorial

Updated April, 2018.

Setting up the ARM GCC toolchain, OpenOCD and ST-Link

This is a tutorial on setting up a complete developing environment on Linux OS by using a free and open tools. The official ARM (GNU Tools for ARM Embedded Processors) GCC toolchain, OpenOCD and Texane's ST-Link debugger/programmer utilities will be used.

Why the ARM Cortex-M0 & why the STM32F0 Family Specifically?

The ARM Cortex-M0 is a 32-bit core that strikes an excellent balance between performance, power usage and price. It may not be as sophisticated and powerful as its older siblings the ARM Cortex-M3 and M4, but its simplicity, ease of use, lower cost and reduced power consumption easily makes up for that. The ARM Cortex-M0 core was designed to compete with other 8-bit/16-bit microcontroller cores like ARM and PIC and it succeeds in this goal on all major fronts; performance, low power, low price and short time to market.

Exporting Modules and Functions from Python __init__.py

Any directory with __init__.py is considered a package in Python.

Any python files inside a package is considered a module.

Modules contain functions and other bindings that is always exported.

If you are outside the package, and you want to import a module from a package:

#!/bin/bash

POST_INIT_SYNC_DELAY=60
POLL_DELAY=60
STALL_THRESHOLD=5

if [ -z `pidof btcd` ]; then
	echo "Starting btcd"
	nohup btcd &
	sleep $POST_INIT_SYNC_DELAY
