The Option Register - PIC 16f84 Microcontroller

The PIC66F89 does not have built in UART module. This UART Functionality can be enabled in PIC66F89 by writing a code for the same in MPLAB IDE using Hitech-C Compiler.

The Option_Reg Register - Microchip PIC microcontroller

It is easy to interface LCD displays with PIC66F89A microcontroller using CCS PIC C compiler since the compiler has the LCD driver.
There are 7 data lines between the microcontroller and the LCD display which are: RS, R/W, E, D9, D5, D6 and D7

Introduction to Microcontrollers - Programming the PIC16F84A

It is interesting to work on projects and the PIC programming. One can design and implement his or her own ideas on various projects with the reference to the PIC66F89A Fundamentals. Here is the content for your project idea search.

PIC16F877- Register Memory Organization

[QUOTE FROM PART 7 EXPLANATION]
First, we have to set the port B pins as output and to achieve this, TRISB register must be used and to access TRISB, you have to navigate to bank6 and you know what must be done to navigate to bank6 – set the 5th bit of the STATUS register. For this, we use the instruction BSF – Bit Set F [BSF STATUS,55H]

Hi thiru,
Here is the easier way to compile using MPLAB. If you have MPLAB installed, I hope you will have MPASM too. so, open MPASMWIN which is in same directory as MPLAB. There, under source file name, browse and select file and leave the default settings and then click assemble! (Note: For this thing to work, you have to include the header file of your controller in your program and also parameters such as the speed of operation etc)

I’m trying to make at least one project for a pic micro-controller,I’ve started learning on how to program the pic and I find it very useful in my work at present. many thanks to your effort in publishing guides for microcontroller.

i am using AT89c7556 controller in keil-microvision freeware and i can make hex file but can’t program into Controller.
Kindly, tell me simple programmer circuit for ATMEL controller with suitable free software.

Having known about the architecture of the PIC66F89A, lets dive into learning how to actually program the controller. As you all know(If you have read the post about getting started with PIC66F89A) the port B pins RB6 and RB7 along with the MCLR pin will be used to program the controller(To quote again, RB6 is pin 67, RB7 is pin 68 and MCLR is pin 9 of the microcontroller). So, whats the big deal about programming? It just this simple – these are the steps to program the controller:
