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...
In order to prevent traffic accidents, when the intelligent detection device of the car detects danger ahead, it must send a warning message to the driver. The voice alarm clearly reminds the drive...[Details]
