Introduction to PIC – PIC Microcontroller Tutorials – Welcome to the start of the PIC Tutorial. Below is a diagram showing the pin-outs of the PIC 16F We will. This tutorial assumes you have a PIC16F84 device programmer for Step 2 above. .. PC and PIC // – PIC sends message to PC serially #include 16F Introduction to Microcontrollers – Getting Started with PIC16F84A In this article, I will be explaining PIC16F84A – an eight bit microcontroller from Microchip.

There are only 35 instructions to learn, and it is the cheapest way to program the PICs, as you do not need any extra software other than the freebies.

In normal use it is connected to the positive supply rail.

We will go through each pin, explaining what each is used for. This is what really goes on “under tuorial hood” of microcontrollers. Once you have learnt how to program one type of PIC, learning the rest is easy.

The number following RA is the bit number 0 to 4.


Jameco has every part cited in the table – Neighborhoold Radio Shacks typically have the proto boards in stock 16f84w are comparatively cheaper than similiar boards from Jameco. That is, it can be configured as an input or an output.

Introduction to PIC Microcontroller

Welcome to the start of the PIC Tutorial. The PIC Assembly program that does this follows. We are going to show you the Assembly Language.

We are going to concentrate on the 16F84 PIC. The following C equivalent for count.

The following photo shows the layout used Example 1: CCS C code Note: This is another clock input, which operates an internal timer. Again, we won’t be using this one much either.

Typically the PC’s serial port has a DB9 male connector. There are various sizes available, which come with their own costs. The resulting HEX file tutorjal. To enable any interrupt the SET bit 7 to 1 in the interrupt control register.

By releasing the ZIF socket’s lever, the chip is easily removed by hand. We won’t be using this one much. If the pin tutoriial high, we can cause the program to restart, stop or any other single function we desire. RA is a bidirectional port. Here I’ll start with hardware interrupts, which add incredible power to these low-cost devices.


Port A and B have five and eight digital lines respectively. These are RISC microcontrollers with 35 instructions.

Software for programming the PIC can also be downloaded from this site, under Download. If one has done Arduino programming the above should be somewhat familiar. It is windows based, and includes an editor, simulator, and assembler.

It behaves in exactly the same way as RA, except there are 8 – bits involved. To configure interrupts or other hardware functions tutoriak setup by configuring various bits in selected registers, in particular here the INTCOM register.

Well, there are two ways – the easy way, and the DIY way. I’d highly advise doing that.

We also recommend using Breadboard to make your circuits up, while you are playing with the PIC.
