Moderator, I have a question!I use the internal AD of 149, and the collected data is unstable. It is the same when the input is directly pulled down. The jump is about 15, and occasionally it will rea...
1. I always thought that the STC microcontroller could download programs after reset, but after remaking the board, I found that the STC can only download programs after each power-on. In this case, t...
