...

SPI_Read(rec)

5.2.15.4 SPI_Write – Sends data via SPI

Prototype sub procedure SPI_Write(dim Data as byte)

Description Routine writes <Data> to SSPBUF and immediately starts the transmission.

Example

SPI_Write(7)

5.2.16 USART Library

USART (Universal Synchronous Asynchronous Receiver Transmitter) hardware module is available with a number of PIC MCU

models. You can easily communicate with other devices via RS232 protocol (for example with PC, see the figure at the end of this

chapter - RS232 HW connection). You need a PIC MCU with hardware integrated USART (for example, PIC16F877). Then,

simply use the functions and procedures described below.

Note: Some PIC micros that have two USART modules, such as P18F8520, require you to specify the module you want to use.

Simply append the number 1 or 2 to procedure or function name, e.g. USART_Write2(Dat).
