Periph
Peripherals I/O in Go
periph is a Go library that unifies hardware I/O on single-board computers and embedded Linux devices, exposing clean interfaces for GPIO, I²C, SPI, UART, PWM, and more. Its philosophy is “no daemon, no codegen”—you link a Go package and speak directly to the hardware via stable abstractions, keeping deployments simple and auditable. The project auto-detects host capabilities at runtime and selects the best driver backend, smoothing over kernel and board differences across Raspberry Pi, BeagleBone, and other platforms. ... -

PyBitBanger
Python controlled hardware.
...The goal of this project is to use relatively simple hardware like an Arduino Nano and the Microchip MCP23S17 port expander as an extensible bit banger. Ideally, all hardware should be leaded and breadboard friendly for easy project prototyping. The ELEGOO Nano is used as an USB RS232 to SPI controller to control the port expander. This fits nicely on a breadboard and has sufficient resources to control a very large number of bits. The Nybble protocol, https://sourceforge.net/projects/nybbler, is used to communicate between Python and and port expander chips. Tkinter is used for both the GUI and as a thread manager for the serial port interface. ... -

EEPROM_editor
EEPROM programmer for the SST39SF040 chip.
...FPGAs are suitable for these applications, but the learning curve is steep, the tools are complex and for small one off projects, not worth the effort. An Arduino Nano will be used as an interposer between a Python script doing the programming and SPI connected port expander chips used for generating the required signals. This makes project development simple with relatively simple tools, simple hardware and a shallow learning curve. The chip is available as a leaded part so wire wrap can be used to quickly build the programmer. Current draw is also low enough that the Arduino can be used to power the programmer. -

ocapi
C-level driver collection for MSP430 and derivatives
...It provides a C language application programming interface (API) for deploying individual processor capabilities. Current modules support serial communication via UART, I2C and SPI, digital I/O (GPIO), analog-to-digital conversion (ADC), Timers and so on. ocapi aims at being independent of the development host platform. So it should work, no matter if you live in the Windows, Linux or Mac world. ocapi is used as the hardware abstraction layer for the MSP430 port of the Takatuka Java virtual machine (JVM). ... -

ESP32 Arduino Reflow Oven Controller
ESP32 Arduino Based Reflow Oven Controller Schematics and Firmware
This reflow oven controller was built to control a modified toaster oven for the purpose of doing reflow soldering of printed circuit boards. The controller was designed and built around an ESP32-DevKitC development board with ancillary electronics added to complete the controller. The schematic can be found in <files/hardware>. The code for the controller was modified extensively from existing Arduino sketches for reflow oven controllers and is PID-algorithm based. The firmware... -

rims-arduino-library
Recirculation infusion mash system library for Arduino
This library implement RIMS controls for home brewers. For definition of a RIMS, see https://tinyurl.com/j3lyuyc For me, an Arduino micro controller + a LCD Keypad shield was cheaper and a lot more customizable than a commercial PID controller. So, with this library, a commercial PID controller is unnecessary. Automatic PID tuning toolkit is also included. Temperature can be read with a thermistor, a resistance temperature detector (RTD) or any custom temperature probe. Heater is... -

stm32f7nucleo-eastrising-7inch-lcd-spi
STM32 Nucleo STM32F746ZG interface to East Rising 7 inch LCD Panel
An STM32 Nucleo-144 development board with Arduino Uno Rev3 connectivity is interfaced via an EastRising Technology Co Ltd Shield PCB to the East Rising 800x480 pixel 7 inch LCD panel with resistive touch screen. A set of functions has been developed to drive the panel via SPI, which uses the RAiO Technology Inc RA8875 TFT-LCD controller IC. Test firmware was developed that uses this function set to explore and demonstrate the many capabilities of the panel. The STM library is used along with FreeRTOS. Please see: LcdTest_ReadMe.pdf or LcdTest_ReadMe.odt. The project is simply a personal record of what has been done, and will not be developed further. -

EtherCard
EtherCard is an IPv4 driver for the ENC28J60 chip
...Non-AVR boards are NOT currently supported (101/Zero/Due) #211 Hardware: Depending on the size of the buffer for packets, this library uses about 1k of Arduino RAM. Large strings and other global variables can easily push the limits of smaller microcontrollers. This library uses the SPI interface of the microcontroller and will require at least one dedicated pin for CS, plus the SO, SI, and SCK pins of the SPI interface. An interrupt pin is not required. Any Arduino IDE >= 1.0.0 should be fine. EtherCard is available for installation in the Arduino Library Manager. Alternatively, it can be downloaded directly from GitHub. -

Heads
A minimal Linux that runs as a coreboot or LinuxBoot ROM payload
...Heads is not just another Linux distribution – it combines the physical hardening of specific hardware platforms and flash security features with custom coreboot firmware and a Linux boot loader in ROM. This moves the root of trust into the write-protected region of the SPI flash and prevents further software modifications to the bootup code (and on platforms that support it, Bootguard can protect against many hardware attacks as well). -

This is a small foot print, high performance, type safe device driver library, initially targeting Arduino Mega 2560 and MoteinoMega. The library is stand alone and only requires Avr GCC and avrlib. The design is based on the same ideas as were used for the Ddr-Z8E device driver library (see http://ddrz8e.sourceforge.net/). Heavy usage of hardcoded invariants, constant folding/propagation and inlining ensures both tight code and high performance. Type safe enums (C++11) provides an...
