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
