Hello friends! In this tutorial, we will learn how to program a PIC microcontroller with code compiled in mikroC PRO for PIC, using a PICkit 3 programmer. The useful idea is simple: mikroC builds the firmware, and Microchip's programming software loads the resulting HEX file into the selected device. The original project behind this lesson required mikroC, while the available programmer was a USB-connected PICkit 3. Moving from a serial-port programmer to PICkit 3 made the laptop connection easier, but the compiler and programmer still needed a common file format. The HEX file provides that connection without requiring us to compile the project again in another C compiler. We will preserve the original MPLAB IDE screenshot sequence, explain what each step does, and cover the important chec ...
