Dear Friends, Right now I am using 4 key to perform the operation like UP, DOWN, OK & EXIT in my project. But Now I want to perform EXIT operation by remaining three keys. How can I prepare the code??? I mean I want to reduce the keypad from 4 keys to 3 keys.... I am using pic16f877 with hi-tech C compiler.. Thank you,
Dear Friends, I am working on TImer 2 of pic16f877. Code is given below. void main() { TRISB0 = 0; RB0 = 0; inittimer2(); while(1) { } } void inittimer2(void) { TMR2 = 0x00; T2CON = 0x75; // Prescaler 4, Postscaler TMR2IF = 0; TMR2IE = 1; PR2 = 0xFF; } void interrupt ISR(void) { if(TMR2I
Hi guys. I'm new to this C programming language. is it possible to display the temperature that measured by LM35DZ to led DOT matrix display? i cant find the tutorials everywhere. Attached the led dot matrix datasheet.
hi ! I'm trying to to make a led light on when i push the button ! here is the situation : - when I push it for the first time, the led lights and switch off after a delay ! but if I push it the second time and she's still lights ( in the delay ) it should turn off I made this prog ! but it didn't work ! I forgot to mention I'm working on p

Simple short code for led Chaser in MikroC : Also you can easily get assembler code in MikroC if you need. The code is the same for pic16f877, just choose that uC in project settings and adjust oscillator. Best regards, Peter
