Arduino library for SX1276 using LoRA and PyQt

This PyQt code sends to Arduino payload binary information prepended by two bytes. 1st byte is function mode and 2nd byte is payload length. This code is able to receive binary information, to add CRC at the end or request a CRC calculation from Arduino. It is attached an example inside loraIno library for Arduino. Hardware is based on… Continueu llegint Arduino library for SX1276 using LoRA and PyQt

How to run in Linux (it has been tested on Debian… Continueu llegint How to deal with binary data between Python and Arduino

SPI – Sample of master and slave using two Arduino

Sample of SPI communication using two Arduino on S4A Programming Learning Board : Arduino’s SPI master code (mirror) Arduino’s SPI slave code (mirror) How it works: When at master board is pressed button attached at pin 2 (zero level), it is immediately received by slave and lits led at pin 3 on. Afterwards, master is reading slave and updates… Continueu llegint SPI – Sample of master and slave using two Arduino
