For electronic systems with microprocessors, anti-interference and electromagnetic compatibility are issues that must be considered during the design process, especially for systems with high clock fr...
I am a beginner in AVR and I have learned about digital tubes. I learned that the digital tube bit selection on the board is controlled by 74ls138, and the segment selection is controlled by 74hc595. ...
I got a mini2440 a few days ago. It's a very nice board. It has a 400M main frequency. When I run uCos2, I find that the speed is very slow, but I don't know why. I suspect that the cache is not used,...
