Static display is a commonly used display method in digital tube displays. Its core concept is to control each segment of the digital tube through fixed signal levels, thereby achieving the display of numbers or characters. In static display mode, each segment is directly controlled by an I/O port of the microcontroller, eliminating the need for additional refresh operations, as the displayed content remains unchanged until the input signal changes.Simple wiring diagram (for simulation purposes only):
Code:
#include<reg51.h>void main(void) { P0=0x92; // Send the segment code for number 5 to port P0 P1=0x90; // Send the segment code for number 9 to port P1 while(1) // Infinite loop, simulation program runs indefinitely. ; }
