In this video, I show you how to make a 10-channel voltage logger that can not only show the measurement data on a display, but it can also log it on an SD card.

The system is driven by a STM32F401CCU6 microcontroller. It has a 1.8" TFT LCD with an SD card slot and a button.

This demonstration and code are a perfect base for building a more complicated logger where you both want to see the data and save it on an SD card.
