Use this code for LCD Data, IRP problem will gone... void Lcd_COut(char row, char col, const char *cptr) { char chr = 0; //first, it is used as empty string Lcd_Out(row, col, &chr); //nothing to write but set position. for ( ; chr = *cptr ; ++cptr ) Lcd_Chr_CP(chr); //out in loop } write in code... ...

I was trying to generate the 50Hz PWM signal. But it dosen't work. Here is my code: void interrupt() { if(CCP1IF_bit) { CCP1IF_bit = 0;// clear flag Clock1 = 0; } if(TMR2IF_bit) { Clock1 = 0; TMR2IF_bit = 0;//clear flag } } // ISR... void PORT_Init(void) { TRISA = 0xFF; // PORTA input TRISB = 0b0000...

Hi, I've solved the problem myself. The problem was I'm taken the variable with a fixed determined value in the first. So each time the power resets, MCU is taking the value from that first declared value. That is why the EEPROM was not working.

Now its ok.

Thanks

How to use EEPROM of pic16f877A? I tried this program. But it doesn't work. This is just a part of the program. The main calculation is done here. int i=0,cnt=0; long tlong, value, askvalue, recentvalue=0; int flag,ss = 0; void display() { ch = (tlong / 10000) % 10; //Lcd_Out(1,3,"Tmp"); Lcd_Out(1,3...
