Jens Chr Brynildsen's Projects
Monochrome OLED library (does not support grayscale)
This is a Arduino library for the Adafruit VS1053 Codec Breakout and Music Maker Shields
Particle Photon/Electron library for the ADS124S08
Various libraries that I either have updated or created myself
MQTT library for Arduino
Particle Photon library for the ST7789 IPS SPI display.
Barebones example of how to show data from a microcontroller (such as an Arduino) on a webpage, hosted locally. Uses Socket.io to send data from the local server to the browser.
This library provides simple usage of the DACx311 ICs from TI. These are single- channel, voltage output digital-to-analog converter and great for setting a voltage reference. DAC5311, DAC3311 and DAC7311 are supported, but only DAC7311 is tested.
Documentation for Particle
Code from lectures in the Edge To App elective at Kristiania University (PGR212)
A Tiny but very functional DevBoard with Temperature/Moisture sensor and 5 programmable LEDs
Kidad files from my two-day workshop on creating an ESP32 based IoT device from scratch.
Resources for the ESP8266
Wifi and MQTT handling for ESP8266 and ESP32
A bare Feather Wing project for Kicad
Firmware for Particle Devices
OS collection of classes that I use for convenience
Little bits of information that you may find useful when interacting with Expo tools and service. Append the markdown filename to https://expo.fyi/ to get a quick link to it.
An open source, embedded, high performance g-code-parser and CNC milling controller written in optimized C that will run on a straight Arduino
Basic Arduino code to control the K750 RFID card reader/writer/dispenser
Schematics, footprints and scripts I've made and tested for KiCad
An Arduino library for the Hi-Link LD2410 24Ghz FMCW radar sensor.
A Feather dev board based on ESP32-S2
Simple library for controlling linear actuators (and anything similar) using forward & backward pins
LiquidCrystal Arduino library for the DFRobot I2C LCD displays
