Logarithmically Controlled Dimming with 64 Steps. Built-in 1. Smart Phones Portable Media Players. STM32 has more features than Arduino board. It requires only two wires.
These values are sent via I2C communication bus. The programming is similar to the Arduino code. This tutorial has two programs one for master STM32 and other for slave Arduino.
Complete programs for both the sides are given at the end of this project with a demonstration Video. First of all we need to include the Wire library for using I2C communication functions. Next we need to call Wire. When Master STM32 request value from slave this function will execute. This function does take input value from the Slave Arduino push button and send a byte 1 or 0 to Master STM32 according to push button value by using Wire.
When Master sends data to slave with slave address 8 , this function will execute.
