Hi, I have a non-profit (Smoky Mountain Scientific, smokymtsci.com) that develops and sells low cost instruments for science education. One of our instruments incorporates a Tiva-C launchpad that outputs a pwm voltage and measures voltage and current passed in electrochemical reactions. I recently purchased a fairly large batch of Tiva launchpads from Mouser and I am having trouble with noise in the analog read channels for about 1/4th of the boards. We have been building and selling these instruments for a couple of years now and have never had this problem before. To test the boards, I
So today I breadboarded an Adesto AT45Dxxxx DataFlash chip with an G2553 (TSSOP28 on a breadboard adapter) and wrote a quick test sketch in Energia using software SPI. The sketch queried the Manufacturer/Device id every second and communication was very spotty with a correct result in only about a fifth of the queries. At first I thought is was a software error so tried various things like adding delay(1-10) after pulling the CS low and stuff like that. Generally it got worse, at least not better. This got me quite confused for an hour or so but during lunch the penny dropped: what if I added
