I'm sorry, I simply can't record a video under 10 minutes.
But in this one, I show you how to control a MCP23017 GPIO expander (yeah, not the boring BMP280 sensor again!) with a Raspberry Pi and I2C by using the programming language C. We will only use some standard Linux function calls and no libraries! Enjoy!
If you need the source code, just let me know and I will upload it to my github repository.
Here is a link to the datasheet of the MCP23017 from Microchip:
