Prototype

sub procedure Soft_SPI_Config(dim byref Port as byte, const SDI, const

SD0, const SCK)

Description Routine configures and initializes software SPI with the following defaults:

● Set MCU to master mode,

● Clock = 50kHz,

● Data sampled at the middle of interval,

● Clock idle state low

● Data transmitted at low to high edge.

SDI pin, SDO pin, and SCK pin are specified by the appropriate parameters.

Example

Soft_SPI_Config(PORTB, 1, 2, 3)

' SDI pin is RB1, SDO pin is RB2, and SCK pin is RB3.

5.2.19.2 Soft_SPI_Read – Reads the received data

Prototype sub function Soft_SPI_read(dim Buffer as byte) as byte

Description Routine provides clock by sending <Buffer> and reads the received data at the end of the period.
