adafruit-ssd1331-oled-driver-library-for-arduino

For 0.96" OLEDs in the Adafruit shop

arm_cortex_m_assembly

Various practical examples for getting started with developing on Cortex-M platforms using Thumb assembly. Work-in-progress as I learn

Cleaned-up version of a toy 3D engine that I had been writing for fun a couple of years ago. I removed unfinished and outdated features and added more explanatory comments, and I'm hoping to use it as a starting point for a Rust and/or Vulkan rewrite.

cortex-m-rt

Minimal startup / runtime for Cortex-M microcontrollers

cortex-m0_c_calling_thumb

A quick 'hello, world' example for mixing ARM Cortex-M Assembly code and C code. Assembly is nice for learning and for realtime applications, but C is nice for the standard peripheral libraries and for code brevity.

cortex_m0_c_calling_thumb

A quick 'hello, world' example for mixing ARM Cortex-M Assembly code and C code.

cp2102n_simple

Simple breakout board for a CP2102N USB / UART bridge.

crouton

Chromium OS Universal Chroot Environment

eeglogger

Program to log EEG data and recognize SSVEP signals. Created by the Washington University in St. Louis Brain Computing Interface club - we decided it wouldn't hurt to open source it.

esp32_minimal

Minimal code for a 'bare metal' ESP32 program which does not use ESP-IDF. Really just a learning exercise because the ESP-IDF is Apache-licensed and quite good; I just had trouble finding lower-level information about the chip.

flexible_plywood_generator

Script to generate flexible rectangular areas of plywood.

fpm-c_stm32_example

Adapted example code from the 'FPM-C' fingerprint sensor library for an STM32L4 core. The library does include an example for the cheap-and-cheerful 'blue pill' board, but I'm not sure what it uses as a build system: https://github.com/brianrho/FPM-C

game_and_watch_fun

Repository containing code to run on a Nintendo Game and Watch.

gd32vf103_templates

A few minimal bare-metal "hello, world" programs to help learn about the GD32VF103 RISC-V microcontroller without relying on a particular framework.

girih_tiles

CAD drawings of Girih tile shapes, with what I believe are accurate proportions

grid_box_pattern_gen

A script to generate simple 'grid box' patterns for a laser cutter.

heartbeat_asic

Example repository containing a simple counter, for use with the SiliconCompiler ASIC build system.

hello_msp430

Just a simple 'blink' program for an MSP430G2553 Launchpad.

holidaystarlights

Addressable RGB LEDs can be a fun and festive addition to any holiday!

ice40_blink

Simple "hello world" FPGA application to test running an nMigen design on an iCE40 chip.

ice40_tests

A couple of simple test programs for iCE40 FPGAs.

inkscape_purge_small_paths

Inkscape extension to remove small shapes from a vector image.

iup_intro

Minimal examples for various UI elements from the IUP library's Lua bindings. Largely derived from: http://webserver2.tecgraf.puc-rio.br/iup/en/building.html

kicad_stm32_example

Example project containing a KiCAD project for a basic STM32 breakout board.

magrat_v0

Design files and test firmwares for a single-core STM32H7 board with extra RAM and a side of Flash.

max31855_breakout

Simple OSHW breakout board for a MAX31855 thermocouple amplifier chip.

mcu_quickref

Not much right now, but I keep having trouble deciding what sort of chip to use for a project. It'd be nice to have an easy way to compare them, although some peripherals might be apples to oranges.

mcu_reference

This is intended to, eventually, be a quick reference for various types of microcontrollers and their capabilities. Peripherals, clock options, memory types, that sort of thing. Eventually, example code would be nice to include. But for now, it's just a mostly-empty project.

micropython

MicroPython - a lean and efficient Python implementation for microcontrollers and constrained systems

min_freertos_blink

An example FreeRTOS project for STM32 microcontrollers. I'm hoping this can be a simple starting point for learning about using a realtime operating system.
