5.2.15 SPI Library

SPI (Serial Peripheral Interface) module is available with a number of PIC MCU models. You can easily communicate with other

devices via SPI - A/D converters, D/A converters, MAX7219, LTC1290 etc. You need PIC MCU with hardware integrated SPI

(for example, PIC16F877). Then, simply use the following functions and procedures.

5.2.15.1 SPI_Init – Standard initialization of SPI

Prototype sub procedure SPI_Init

Description Routine initializes SPI with default parameters:

● Master mode,

● clock Fosc/4,

● clock idle state low,

● data transmitted on low to high edge,

● input data sampled at the middle of interval.

Example
