=Hello, the source code "ST7SCR-Demo_Sources" of the "Smart Card Reader ST7SCR Evaluation Board" downloaded from the ST website failed to compile. I did not make any changes. The error message is as f...
Basically, matrix keyboard scanning is written like this. The key is to master this idea. Scan the rows first, then scan the columns. You can use it directly, and the effect will be better with softwa...
What is the reason? I know it's hard to say, but I connected it according to the datasheet. The effect is not good when using opa694 as the pre-stage follower input. It is not good when using opa690. ...
