Schematic diagram:
Keywords：Drive
Reference address：Drive four LEDs to flash
Keilc51 Program:
#include
void main(void)
{
long int i,j;
while(1)
for(i=0;i<9;i++)
{
P2=0x00+i;
for(j=0;j<10000;j++)
{
}
}
}
After joint debugging, you will find that the lights of four different LEDs flash regularly; and the voltage value of ABCD can be measured by the oscilloscope. When the LED is on, the voltage at the test point is 502.6mv, which is a low level, so the diode is turned on; when the LED is off, the voltage is 4.995V, which is a high level, and the diode will not be turned on; VCC is 5V voltage; a certain position of P2 port in the C51 program is a high level;
