PIC microcontroller | Flashing LED
In this article I will look at flashing an LED on/off using a external clock delay. If you have not already read my previous articles, Pre-coding preparation and LED On, please do so now. Many of the concepts I have discussed in earlier articles will come into play in this project. With this project, I will be using an external 20MHz clock instead of the built in 4MHz clock that comes with the PIC16F628A chip. To do this, I looked…
