Hello everyone: I am a microcontroller beginner. I used a 51 microcontroller to write a digital tube dynamic program. The purpose of the program is to use the dynamic scanning method and timer 1 to di...
As shown in the figure, I converted +5V to -5V through MAX735, and then supplied the positive and negative 5V to the dual power amplifier. Once powered on, -5V was pulled down to 0V. After disconnecti...
