ESP32 Bit Pirate
A Hardware Hacking Tool with Web-Based CLI That Speaks Every Protocol
ESP32 Bit Pirate is open-source firmware that turns supported ESP32 devices into portable hardware development and analysis tools. Inspired by the Bus Pirate, it communicates with digital buses such as I2C, SPI, UART, 1-Wire, CAN, and direct GPIO. It also supports wireless and radio technologies including Wi-Fi, Bluetooth, Sub-GHz, RFID, infrared, and RF24. Users can interact through a USB serial terminal, a Wi-Fi web command line, or a standalone screen and keyboard on compatible hardware. The firmware can sniff traffic, send data, read memory devices, scan interfaces, manipulate pins, and automate operations with scripts. ... -

TFT_eSPI
Arduino and PlatformIO IDE compatible TFT library
...The library can be loaded using the Arduino IDE's Library Manager. Direct Memory Access (DMA) can be used with the ESP32, RP2040, and STM32 processors to improve rendering performance. "Four wire" SPI and 8 bit parallel interfaces are supported. Due to the lack of GPIO pins, the 8-bit parallel interface is NOT supported on the ESP8266. 8 bit parallel interface TFTs (e.g. UNO format mcufriend shields) can use with the STM32 Nucleo 64/144 range or the UNO format ESP32. ILI9341 and ST7796 SPI-based displays are recommended as starting points for experimenting with this library. ... -

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). -
