In today's video, I go over the process involved when using DMA and Timer Channels in the STM32CUBEIDE. Both DMA and Timer Channels were needed for an ongoing project I am working on involving an MQ2 gas sensor.

If you haven't seen the previous video regarding this project, check it out here: https://www.youtube.com/watch/yeCud.... A video of the PCB along with fully implemented code for the project will be coming out shortly.

Leave a comment below and let me know your thoughts on how I implemented this code and any improvements that can be made to my content.
