For when you need to quit an Eclipse running in a different X session:
#!/bin/sh
ECLIPSE_VERSION=46
ECLIPSE_HOME= ## path to the jar referenced in the next line ##
ECLIPSE_CMDLINE_MATCH="jar ${ECLIPSE_HOME}/plugins/org.eclipse.equinox.launcher"
# This just leaves an orphan
killall eclipse${ECLIPSE_VERSION} 2> /dev/null
# This still just leaves an orphan
killall eclipse 2> /dev/null

A script that turns a BDF bitmap font into a dictionary of bitmaps
#!/usr/bin/env node
const regrep = require('stream-replace');
/* Stream in, stream out.
The output will look something like this:
{ "${code_0}": ["${hex^0_0}", ..., "${hex^0_n}"],
"${code_1}": [...],

MP Select Mini USART Interface

MP Select Mini

The serial cable (that ordinarily connects to the LCD controller) has four wires: Red, White, Green, Black.

  • Red ➙ Ground
  • White ➙ TX USART1 - pin 42†
  • Green ➙ RX USART1 - pin 43†
  • Black ➙ +3.3V (yup, they're backwards)

†: on the STM32 processor
