I promise to use it only to send you MicroZine. A tutorial on the 12F PIC microcontroller which shows you how to program and use it with a series of projects starting out with a simple LED flasher and progressing on to more advanced projects.

Although the 12F is an older device it is still a useful one and has many peripehrals built into it including the standard 10bit ADC. In fact it has two timers and analogue comparator and the ADC which can read analogue values from 4 pins. With its 1k of programming memory you can make this device do many different tasks. If you do want to re-compile the source code the compiler is free for the small amounts of code used here as they all generate hex output files that are below the 2k limit.

So learning about this peripheral is also useful for these other parts. The following bubble diagram shows the major peripherals and features of the 12F in a visual format:.

ICSP connections are shown in the diagram below. Other views:. All you will need is a wall 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 You would not want to use that high voltage for very long if using reasonable current as the would have to get rid of the excess power as heat. Before Programming it with your hex file make a note of the oscillator calibration value which is factory set by Microchip.

If overwritten you have to re-calculate it yourself. Click here for m ore detailed information in a further tutorial and then come back here. If you use ICPROG then it warns you that you are about to overwrite the oscillator calibration value and asks if you use the value from the hex file - you should answer No to keep the original value. Note: Each oscillator calibration value will be different so you have to note down each value for each chip and not muddle them up!

If you loose it you can recalculate it but you will need a frequency counter. This is a tip I have seen on the web for storing your calibration value on the device itself - it's so good I thought I would include it here. All you do is think of the pins of the 8 pin device as a binary number and mark those pins with the value you read out using the programmer in read mode All you need is the last hex number as the 1st is always So lets say you read your device and get C.

Just use the 8C part. As with the 16F88 the 12F microcontroller has eight oscillator modes but unlike the 16F88 the internal oscillator is fixed at 4Mhz. You can use an external oscillator either a resistor capacitor pair, an external clock signal or a crystal or resonator.

You can even operate the crystal to 20Mhz if you need extra performance. The first program is a flashing LED - it always is! The reason is that there is the least hardware to go wrong so it gives a good test of your system setup.

This project also uses the 12F's internal oscillator and you don't need a crystal so there is even less to go wrong! Use the solderless breadboard to construct the following circuit: Note: Double check your connections on the breadboard. Note: the plus sign on the 10u electrolytic capacitor which must connect to the positive input voltage and have a voltage rating stamped on it of greater than 35V or greater than your maximum dc power block output. The LED must be connected with the flat side to ground.

The following diagram shows the above Plugblock circuit in schematic form. It is exactly the same circuit but lets you view the circuit in an easier way and shows the layout of the circuit from the point of view of the circuit block functions rather than how you have to place the components using the Plugblock.

Note: The LED current limiter resistor 1k is not the ideal one it just lets you see the led you don't need the maximum current to see the light from the LED - to use the LED at higher output replace it with R. Remember to note down the contents of address 0x3FF. You can use the hex file directly to program the 12F then it will flash the led on and off or you can re-compile the files using the free compiler from Mikroelectronika.

You can find a very brief compiler tutorial here. Some of the C source code is :. Here all bits are zero so all GPIO bits are set as outputs. Comments Have your say about what you just read!

Learn about the tool used for creating this diagram. Note: Using the above programmer circuit sometimes you need to remove the ICSP connector this is easier than removing the whole chip.

I have used a 4 pin molex with wires soldered to the base these go into the solderless breadboard making removal trivial. Sometimes you need to remove it as the programmer does not release Vpp PC software operation and at other times you will need to remove it as you will want to read the analogue voltage at the ICSP pin see temperature logger in a further tutorial.
