My microcontroller is STC89C516RD+ (crystal oscillator 24MHZ). After D/A (8-bit) conversion, I get a fixed frequency sinusoidal signal, but I want it to achieve stepping. My idea is to change the dela...
I have simulated this circuit, and it is basically consistent with the actual test, but the problem is that the expressions of the voltage output Vo and voltage Vi that I calculated now do not seem to...
There are two ways to implement firmware update: burning in system program and resident update program; System program burning is the tool used by managers to directly update the firmware. Flash burni...
