The IDE is an environment which integrates different simulation tools and compilers to provide a single window solution to development and debugging. Two values stored in file register locations 0x20 and 0x21 are to be added and the result stored in register 0x Writing a 1 into the corresponding TRIS bit configure the port pin as an input pin, and the data comming in throught the port pin will be latched into the corresponding PORT bit in the immediatly next execution cycle.

Consider a laundry with one washing and one drying machine. The individual port pins are named 0 throug n.

The programs written using these basic instructions are called assembly language programs and is the most primitive not exactly, but close [: Thereforewhen we are referring to switching a port pin on as in tha air conditioner, it is actually writing data into the corresponding port register.

Most of the device vendors provide a free asembler for their parts. To activate the colour coding that will highlight keywords, type in something and save the file with the. Leave a Comment Your email address will not be published. It is also easier for us to keep track of our files this way.


Before the transfer the appropriate bank is also to be selected. I hope you have also gone through the instruction set summary Section 15 of datasheet as instructed. The working register, commonly referred to as the W reg, is the only scratchpad memory register accessible to the user in the PIC 16Fa. A micro-controller, in simple words, is a miniature computer with a central processing unit and some peripherals integrated into a single integrated circuit package.

A detailed explanation if the instruction set will follow later on in the tutorial, but for easy understanding of many of the concepts, it is advised to thoroughly go through the instruction set summary given in section 15 of the datasheet 6pages before proceeding further.

This will be mainly my taking simple examples and running it in the simulator in the initial stage and later on using the hardware itself.


Once the code is entered, it needs to be compiled. Every data transfer in or out of the RAM register has to go through the W reg. When converted to time, it will be a delay of x1us assuming a oscillator frequency of 4Mhz. This new location is used by the execution unit to fetch the next instruction.

The second form is easier to understand and manipulate from a programmers point of view. The later step is to keep the animation steps visible. After the first program, we are now all set to try out more interesting stuff. A complete list of instructions and their encoding is given in page of the datasheet.

This is dome by the assembler software.

In the above code snippet, the PC increments by one until the execution unit receives the call instruction at Now, we are ready to start the simulation and watch the internal operations of the microcontroller.

Scratch pad memory registers are high speed memory registers which are integral to the processing center architecture. We can use this pause to make required readings and continue with the simulation. But we need to have a control as to in which step of the execution, we need to pause to read out the register values from the watch window. The table of selection values is given below.

It resides outside the RAM register block. These instructions are stored in the program memory in an encoded fashion.

Dafasheet and optimized form of programming. In case any of the components are not correctly pointed correctly, a red cross mark appears near the component. It provides working space for the data manipulation during the command execution.

Other methods are also available, which will be discussed later.
