The STC10F10XE timer interrupts the output of a 10 kHz square wave program, and stc10f10xe10khz

The STC10F10XE timer interrupts the output of a 10 kHz square wave program, and stc10f10xe10khz

// The hardware is also used to test the program. In order to test the new motor drive board, a 51 board is found as a 10 k signal generator to test the time delay of the IGBT switch.
