How to Use SPI Communication in STM32

In this STM32 SPI Example, we will use Arduino UNO as Slave and STM32F103C8 as Master with Two 16X2 LCD display attached to each other separately. Two Potentiometers are also connected with STM32 (PA0) and Arduino (A0) to determine the sending values (0 to 255) from master to slave and slave to master by varying the potentiometer.

Arduino SPI Tutorial

In this tutorial we learn about SPI protocol and how to use it in Arduino. We will use SPI Protocol for communication between two Arduinos. Here one Arduino will act as Master and another one will act as Slave, two LEDs and push buttons will be connected to both the arduinos. To demonstrate SPI communication, we will control master side LED by the push button at slave side and vice versa using the SPI Serial communication protocol.
