sfr ldata = 0x90; sbit rs = P2^0; sbit rw = P2^1; sbit en = P2^2;
void main(){
LcdCmd(0x38); Delay(250); LcdCmd(0x0E); Delay(250); LcdCmd(0x01); Delay(250); LcdCmd(0x06); Delay(250); LcdCmd(0x86); Delay(250); LcdData('M'); Delay(250); LcdData('B'); Delay(250); LcdData('D'); } void LcdCmd(unsigned char value){ ldata = value; rs = 0; rw = 0; en = 1; Delay(1); en = 0; return;
} void LcdData(unsigned char value){ ldata = value; rs = 1; rw = 0; en = 1; Delay(1); en = 0; return;
} void Delay(unsigned int itime){ unsigned int i, j; for(i=0;i<itime;i++) for(j=0;j<itime;j++);
}
please help me
Hey guys. SO..... I was just wondering.. what would be the simplest way to control a floppy drive motor to the 80c517a? Simplest to connect aswell as program? well written code and examples?
Another posting genius.
The motor is typically controlled by an open-collector driver arrangement. Drive it low, motor starts.
Presumably you want to do more than start the motor. If you want to utilize the floppy you will need an FDC (Floppy Disc Controller) chip, like an 756, 8272, 82077
