Cara program ic pic16f84

Here is the code — you will learn it as you progress. What the above program does is that, it delivers a high output on RB7 and can be checked with a multimeter or by connecting a LED. To achieve the aforementioned result, these are the steps.

Because, It considers all the words that appears without a space as labels. After writing the program, in the assembler window, goto tools and select assemble and load option. This option will assemble the program and load it into the simulator. Then select the microcontroller view from tools menu in the simulator main window.

When you select simulation — start, you must see the result in the microcontroller view. This is the software verification part. Having built the programmer, now, load the controller into the programmer and then connect it to the serial port of your PC or to your USB port if it is a USB programmer. Now, the file you need to write into the controller is the. You can find this file in the directory in which you saved the.

Now, open and browse to the. Below is a very simple setup in order to check your programming. Just pop out the PIC from the programmer and wire it in a solderless breadboard as show below.

Regarding crystal. You add an external crystal to pic as shown on circuit. There, under source file name, browse and select your. 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. Kanniyappan: No! To program PIC16F, buy a pickit 2 programmer or build for yourself a pickit 2 clone. I am having a problem when looking at the sample code and your detailed code explanation.

I am refering to the register file map image for the PIC16F84 as was shown on part one of the tutorial and getting somewhat confused. If not, then take a look at it. Author Anish Website. July 10, The most useful feature of this microcontroller is that it's flash based so it can be re-programmed many times. Warning the 16F84 is obsolete. In fact the 16F88 is a good PIC micro to progress onto after starting out on the 16F84 as the 16F88 is backwards compatible with the 16F84 -it has the same number of pins and same pin functions.

Some pins are more flexible but still backwards compatible with the 16F Note: You can't easily go from a 16F88 back to a 16F84A, as the 16F88 lets you use pins in a more flexible manner e.

You'll also need to download the C compiler for source code re-compilation if you want the re-compile code. The compiler is free for the small amounts of code used here. Jump to Circuit diagram. Before you start have a look at the following for background info:. The 16F84 is packaged in an 18 pin chip and although it has limited peripherals it is usable in many circuits.

Here are its features and a short comparison. The following bubble diagram shows the major peripherals and features of the 16F84 in a visual format:. Note: You can compare this chip using bubble diagrams to some others used on this site by clicking here. If you don't have a bench power supply then you can use this circuit. All you will need is a power supply block with dc output greater than 8V and no more than 35V or a 9V battery to plug into CN1.

Note: It is best to use the 5V power supply circuit as it not only correctly regulates the dc voltage but it protects your PIC chip. The input voltage can go up to 35V without damaging the although the power dissipated by the will increase for higher input voltages i. Note: The LED current limiter resistor 1k is not ideal it just lets you see the led you don't need maximum current to see it - Replace the 1k with a if you want brighter output.

The following code flashes the LED. Download the source file and hex files here. You can use the hex file directly to program the 16F84 then it will flash the led on and off or you can re-compile the files using the Mikroelectronika compiler MikroC.

Setting a bit in the TRIS register to zero sets the pin direction to an output. This gives you the basis for using the PIC16F84 so that you can move on to more complex projects. Read more. One common problem: Programming a sketch into the chip without a reset control - solved here.
