Prototype void Spi_Init_Advanced(char master, char data_sample, char
clock_idle, char transmit_edge);
Description Configures and initializes SPI.
Spi_Init_Advanced
or
SPI_Init
needs to be called
before using other functions of SPI Library.
Parameter
mast_slav
determines the work mode for SPI; can have the values:
MASTER_OSC_DIV4 // Master clock=Fosc/4
MASTER_OSC_DIV16 // Master clock=Fosc/16
MASTER_OSC_DIV64 // Master clock=Fosc/64
MASTER_TMR2 // Master clock source TMR2
SLAVE_SS_ENABLE // Master Slave select enabled
SLAVE_SS_DIS // Master Slave select disabled
The
data_sample
determines when data is sampled; can have the values:
DATA_SAMPLE_MIDDLE // Input data sampled in middle of interval
DATA_SAMPLE_END // Input data sampled at the end of interva
l
Parameter
clock_idle
determines idle state for clock; can have the following values:
CLK_IDLE_HIGH // Clock idle HIGH
CLK_IDLE_LOW // Clock idle LOW
Parameter
transmit_edge
can have the following values:
LOW_2_HIGH // Data transmit on low to high edge
HIGH_2_LOW // Data transmit on high to low edge
Requires You need PIC MCU with hardware integrated SPI.
Example This will set SPI to master mode, clock = Fosc/4, data sampled at the middle of interval,
clock idle state low and data transmitted at low to high edge:
Spi_Init_Advanced(MASTER_OSC_DIV4, DATA_SAMPLE_MIDDLE,
CLK_IDLE_LOW, LOW_2_HIGH)
