How to Use SPI Communication in STM32 Microcontroller

Check the complete tutorial on STM32 SPI communication: circuitdigest....
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.

Really cool! I think you should correct "Salve" no "Slave" in display message, don't you?

Very interesting video. Would you kindly manage to make a video with the relay management via Blynk using stm32 and using a mcp23017 both in input through physical buttons and one in output to manage more relays? Thank you very much for the attention
