What do you need to develop with a PIC microcontroller?

　　PIC microcontroller, manufactured by Microchip. At present, it has many types of microcontrollers, and domestic microcontrollers with the same alternatives include Yingruien's EN series. But here only PIC18F452 is taken as an example, so let's make some brief introduction to PIC18F452.

　　PIC18F452 is a 40-pin microcontroller. Each pin has its own function, which will not be described here.

　　So let's say I want to create a project about blinking an LED. This is one of the simplest projects for PIC microcontrollers, so it might be a very simple and straightforward way to introduce the PIC18F452.

　　First, I need the following so that I can use them to work with the PIC. In another article, the engineers at Inruien Microcontroller discussed some other features available in the PIC18F452 microcontroller, which you can check out.

　　1. MPLAB

　　MPLAB is a software that you can download from the official website of Microsoft, it is an open source software. In MPLAB, you will use assembly and C language for programming.

　　PIC Programmer

　　There are many PIC programmers available in the market. You have to connect this programmer with the PC through the serial port (Parallel port and USB port PIC programmers are also available) and put the PIC microcontroller in the 40 pin socket.

　　3. PICpgm software and PICKit software

　　This software is used to burn programs in PIC microcontrollers, just like burning movies on DVD. You can open the software and browse to the program you made in MPLAB, and then burn the PIC program to the chip.

　　4. PIC basic circuit

　　To get the PIC microcontroller running, we have to add a simple circuit to make it work. The following figure shows a simple PIC circuit. This is not difficult to do and you can solder it on a simple soldering board. The circuit is as follows:

　　Now remove the PIC microcontroller from the programmer and add it to the hardware circuit. You can check the result of programming the PIC microcontroller.
