Hello everyone
I am trying to write program using the PIC18F45K80 microcontroller that controls a set of LEDs connected to PORTB pins. The LEDs should exhibit three states: OFF, ON, and BLINKING. The program should , turning off the LEDs in the OFF state, turning them on in the ON state, and making them blink five times in the BLINKING state.
I have written simple program on tested on PC
PC program
Output
ALL Lights ON
This program should turning ON all LEDs using a switch-case structure and an enum but I don't understand why LEDs are not turning on the state "ON" ?. I am sure there is no problem in connection.
