Spi_Init_Advanced
Prototype
void Spi_Init_Advanced(char master, char data_sample, char
clock_idle, char transmit_edge);
Description Configures and initializes SPI.
before using other functions of SPI Library.
Parameter
The
Parameter
Parameter
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)
MikroElektronika: Development tools - Books - Compilers
determines the work mode for SPI; can have the values:
mast_slav
// Master clock=Fosc/4
MASTER_OSC_DIV4
// Master clock=Fosc/16
MASTER_OSC_DIV16
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
determines when data is sampled; can have the values:
data_sample
DATA_SAMPLE_MIDDLE // Input data sampled in middle of interval
DATA_SAMPLE_END // Input data sampled at the end of interva
determines idle state for clock; can have the following values:
clock_idle
CLK_IDLE_HIGH // Clock idle HIGH
CLK_IDLE_LOW // Clock idle LOW
transmit_edge
LOW_2_HIGH // Data transmit on low to high edge
HIGH_2_LOW // Data transmit on high to low edge
