Proteus simulation of MCU driving 4-phase stepper motor-EEWORLD

Collect

The IO driving capability of the microcontroller is not enough, so the ULN2003 driver is used.

It adopts 4-phase 8-beat drive mode. The stepper motor is motor-stepper in proteus. The connection method is: the middle lead is connected to the power supply, and the other legs can be connected clockwise or counterclockwise.

The procedure is as follows:

#include
#define uchar unsigned char
#define uint unsigned int
void delay(uint a);
const uchar step_table[]={0x04,0x0c,0x08,0x18,0x10,0x30,0x20,0x24};//4相8拍方式
void main()
{
uint i,j;
j=300;
while(j--)
{
for(i=0;i<8;i++)
{
P0=step_table[i];
delay(1);
}
}
while(1);
}
void delay(uint a)
{
uint i,j;
for(i=a;i>0;i--)
for(j=122;j>0;j--);
}
