Pic16f628a led projects circuits
You will need to use a suitable DC power supply rated between 9 and 12 volts and able to supply at least mA. If the condition is satisfied we call our function with the parameters 1, 3, 7 and Helena St. The best way to understand any program is to start from the main void main function, so let's do that. A function can have more than one parameter. This specifically deals with the bit 7 leaving the other bits to its default values.
This simple circuit functions as a 12 LED chaser. A single illuminated LED 'walks' left and right in a repeating sequence, similar to the effect seen on KITT, the.

Once the function is called, the below lines in the function definition will be executed.

I've also written a version for the PIC16FA which is a pin compatible replacement for the 16F84A and I would recommend that if you intend to develop your interest in PIC microcontrollers you start using this device rather than the 16F84A. As noted elsewherethe code above will not work with the non 'A' suffix parts.

Once you've done this, program the 16FA with the new ledchaser16FA. Diode D1 protects the circuit from accidental reverse polarity of the input voltage.
We will dump the program to our PIC microcontroller.

Log in or register to post Comment. Practical PIC Projects. I have also attached the simulation and program files here. Related Content. Diode D1 protects the circuit from accidental reverse polarity of the input voltage.
The first few lines are for setting up configuration bits which were explained in the previous tutorial so I am skipping them for now.

|All MCU mostly use weak pull up resistors.
Helena St. Now you can tweak around the code to get your different sequence of LED blinking. The board includes a 5 volt regulator and reverse polarity protection diode on board. Capacitor C3 is used to decouple the 5 volt power supply rail.
