The device enters the programming mode by applying a set of signals to the programming pins.įor example, for PIC16F88X the programming mode can be activated by holding ICSPDAT (PGD) and ICSPCLK (PGC) low while raising MCLR pin from VIL to VIHH (13V), then applying VDD and data. How does the microcontroller know that it is in programming mode? This means that the pins used to program the microcontroller can also be used as a GPIO pin after programming is completed. ICSP is a technique where a device is programmed even after the device is placed in a circuit board.

The disadvantage of this method is that an extra program space is used for the Bootloader. This technique is used when there are frequent firmware updates in the system. This technique uses a special program known as a Bootloader to write the code into the controller’s program memory via different interfaces such as UART, SPI etc. In general, there are two methods for programming PIC devices. So let’s get into these topics one by one.

In order to learn how to burn programs into a PIC microcontroller, you need to understand the following topics: One important note before we start, is that if you plan on buying a PICkit3 programmer/debugger, make sure you buy it from Microchip or Microchip authorized dealers only, otherwise there’s no guarantee that the programmer will work, in fact we had to buy a second PICkit3 because the first one we bought was a Chinese clone and didn’t work. There are several programmers available out there but we will be using PICkit3 for this example due to its versatility. For programming PIC microcontrollers we require a piece of hardware that can communicate between the computer and the microcontroller known as a programmer.
