I don't understand, is it the problem of the quarters version? The official ones are all 925 but the frequency division is biased. In addition, the system I compiled has this problem: 34.056675] mmcbl...
A potentiometer is needed in the production of a voltage-regulating power supply. However, the shaft of the purchased potentiometer is too large and the existing knob cannot fit on it. So I had to use...
I used assembly language to develop a F28035 project. When calling a function in an interrupt, a fault occurred after programming (it seemed to be running away). After eliminating the problem of savin...
