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.

An effort was made to find a single source supplier of all parts. Jameco has every part cited in the table – Neighborhoold Radio Shacks typically have the proto boards in stock and are comparatively cheaper than similiar boards from Jameco.

116f84a Part connection methods and part locations are not critical. The left photo below shows a part layout that works well. You will need Adobe’s free Acrobat reader to view it.


The schematic and constructing the circuit are relatively straight-forward. Some highlights and clarifications towards circuit construction are given next. By releasing the ZIF socket’s lever, the chip is easily removed by hand.

Closing the lever securely fixes the chip in the socket. Port A and B have five and eight digital lines respectively. The PIC circuit features 0. Although only tuotrial DIP positions are used because Port A has only five digital linesall eight were wired.

The following photo shows the layout used Example 1: The resulting HEX file helloLed. At first glance, the book can appear difficult to read but it really isn’t and I totally recommend it for understanding the assembly language statements given in the above program.

You should see the appropriate LEDs light up. A loop can be implemented to increment a counter. The PIC16F84 assembly code for this follows. The resulting HEX file count. Count to at 1 second intervals and display on LED in ; binary. The following C equivalent for count.


PIC16F84 Fundamentals

CCS C code Note: The resulting HEX file syLed. Successful compiles will generate syLed.

For example setting the first five DIP positions high places in binary 31 in decimal 16g84a Port A. The PIC Assembly program that does this follows. The resulting HEX file hellodip. The ASM code follows: Typically the PC’s serial port has a DB9 male connector.

The PC run a terminal program like Windows’ Hyperterminal.

The PIC can send or receive 8-bit values at prescribed intervals baud rate.
