1 Introduction Recently, I’ve been working on my graduation project. The second board has arrived, and I’ve basically debugged all the components, with a few chips still having test code written for them. One of the chips is the BMP280 barometric sensor, which worked perfectly on the first board, so I can rule out issues … Read more
