Greetings, sir. Before I ask, I would like to thank you for all the tutorials you’ve created and posted in this website.

I have a few question to ask regarding to my circuit in proteus. I’ve constructed the circuit you gave in the picture above. I also built the program using the hitech C compiler using Mplab software. And then, when I try to run the simulation in the proteus using the program i built, it didnt even say error or something like that, instead the led in the circuit itself wont light up. I tried to reinstall all my programming software (mplab, proteus, hitech c). it doesnt work. What should I do. This is really stressing me out. Your tutorials are the only source I have to learn about embedded programming.

Thank you.

Above example is 100% working ? Make sure that your oscillator frequency is 8MHz and Pull up resistor for the switch is there.

In reply to edwin. You can you MPLAB IDE for that. No need of any compilers like Hi-Tech C or XC8.

In reply to adityaukey. It is very simple. Declare a char variable and increment it during each key press. Write that character to PORTD. PORTD = a;
