Three Ways to Make Arduino Works As A USB/TTL Converter
https://www.electronics-lab.com/three-ways-make-arduino-works-usbttl-converter/
Even if you have years working with electronics, you will still find some simple hacks that you never thought about before. Personally and to save money, when I was a student with a very limited budget I knew that my Arduino UNO can work as a USB/TTL(serial) converter. I used to remove the Atmega328P from […]
Robust C Library and Utility for GPIO sysfs Interface in Linux

Iolinker is a cheap 64 FPGA board with a MachXO FPGA that functions as a dynamically configurable IO matrix. Its main functionality, besides IO extension, is to dynamically set up a matrix of GPIO connections, that allow direct pass-through of high-frequency signals. Circuits can thereby be configured and programmed on the fly. There are UART […]
