Hi everyone, I'm working on a project - just for learning - where I'm trying to send joystick position - analog data - from Arduino UNO to Raspberry Pi 3B+ (WiringPi Library) using SPI protocol. So far, I've managed to get both devices communicating using some example code from the internet (i.e.…

Thanks @Idahowalker I've managed to send 4 bytes from arduino slave to RPi master. I've changed the code in the RPi by adding a for loop. RPi Code #include <iostream> #include <wiringPiSPI.h> #include <unistd.h> //for sleep function #define SPI_CHANNEL 0 #define SPI_CLOCK_SPEED 1000000 unsigned…

Hi @Idahowalker
Sorry, breaking the bytes wasn't what I was looking for.
I was wondering how to use SPDR to send a different value to the RPi.
