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.
