PIC16F877 Feature Tutorials

The PIC16F877 is a very powerful and versatile microcontroller. This series of tutorials covers the features of microcontroller describing how to access the features of the micro.

If it isn't tested it probably doesn't work.  The following are not yet fully implemented

The I2C doesn't support all modes

SSP is not implemented yet

Reset is not fully supported

USART does not yet support 9 bit addressing

NOTE: This tutorial series, is for advanced users. You should be fluent with MPLAB and the PIC16F877 instruction set. If you are a beginner you should refer to the Tutorial series for the PIC16C55 which introduces in more detail microcontroller concepts and the MPLAB development environment.
