I have searched many previous articles, but still can't solve my problem of reading the serial number of the SD card. To be honest, I haven't done it yet. I don't know why. I hope the following code c...
I made a single-chip minimum system, but when I use the P0 port (with a pull-up resistor) to control the LED light, #includereg52.h sbit feng=P0^1; int i; void main() {i=10000; while(1){feng=0;while(i...
The efficiency of using MC34063 for step-down is indeed lower than that of professional IC, but it is still a good solution as a low-cost solution.
If the requirements are higher, you can use PT4115 o...
