Я пытался запустить код в MPLAB для сопряжения сканера отпечатков пальцев с PIC16F877A и ЖК-дисплеем, но код выдает ошибки
Вот код

Предполагается, что код связывает PIC16F877A с ЖК-дисплеем и сканером отпечатков пальцев для имитации proteus, но в коде, похоже, есть ошибка, которую я не могу понять при запуске на MPLAB.
