Hi everyone I have a small gap in a program
I'm still in good beginner programmtion but I want improved my knowledge.
I want to set the 16F84A with mikroC for it illuminates the LEDs at specific requirement I will explain my purpose
* two LED lights in the PORTB when I press a Button (entered the port A) I want LED1 port B is extinguished when I release either on, and the same principle for the second led2 except when both botton are supporting a 3 rd lED should be lit means;
is a0, a1 of the input b0, b1 and b2 outputs
** a0 = 0 and a1 = 0 => b0 = 1 and b1 = 0
** a0 = 1 and a1 = 0 => b0 = 0 and b1 = 1
** a0 = 0 and a1 = 1 => b0 = 1 and b1 = 0
* a0 = 0 and a1 = 0 => b0 = 0 and b1 = 0 and b2 = 1
I realized a small program and I simulate it on proteus isis it works with a small defect in the program when I press the botton LED 1 is off and that I release it remains extinguished!
