Can anyone help? We need to use special function of the microcontroller like watchdog timer, timer, and interrupt for our project.
We are using assembly language, we are going to use those in LED, 7 segment and LCD.
I have here a sample program of our running lights of LED.
Can anyone help us? 1 watchdog for that program, interrupt and timer, Can anyone help me
