I’m not sure how everyone prints debugging information during microcontroller development, but most likely, it’s done through serial debugging. In most cases, a serial port is reserved for debugging during board design and coding. But what if you haven’t reserved a serial port during actual development? Actually, our downloader can be used as a debugging … Read more
