I am working on making a digital thermometer using MPLAB and XC8 compiler and PIC16f1829 microprocessor and LM35 temp sensor. So far I have the developed the code below. I need help with the rest of the code for the ADC anlogue to digital converter and display the result on a 16x2 LCD display thanks.
