The libmaple libraries, on which STM32duino is based, provides access to registers by the syntax:

GPIOA-&gt;regs-&gt;REG

Some useful YARD Stick One notes

This thing is a bit of a beast. People don't give it NEARLY the credit, or the documentation it deserves.

Two ways of using this thing: rfcat directly, or write a python script for it.

Basically, writing a python script is easier. Using rfcat directly is great but often, there are just too many silly settings to configure

Stop all containers

$ docker stop $(docker ps -q)

Build docker image

$ cd /path/to/Dockerfile

Gnuk Token on ST Dongle with STM32F103CBU6

Based on Daniel Kucera's implementation of the confirmation button, adapted for a different ST Dongle using an STM32F103CBU6 microcontroller.

Order of the 4 SWD interface holes from left to right:

It's not immediately obvious how to pull down the code for a PR and test it locally. But it's pretty easy. (This assumes you have a remote for the main repo named upstream.)

Getting the PR code

Make note of the PR number. For example, Rod's latest is PR #37: Psiphon-Labs/psiphon-tunnel-core#37
Fetch the PR's pseudo-branch (or bookmark or rev pointer whatever the word is), and give it a local branch name. Here we'll name it pr37:

$ git fetch upstream pull/37/head:pr37
