Soft_Spi_Init(PORTB, 6, 5, 7,

SOFT_SPI_PRESCALER_256, SOFT_SPI_LO_2_HI_IDLE_LO, SOFT_SPI_MODE_8) ---what is it?

and for AT90S2313 PORTB.6 is miso_do
portb.5 is mosi_di
portb.7 is sck
in help
Soft_Spi_Init(PORTB, 6, 5, 7 ) === Soft_Spi_Init(PORTB,sdi,sdo,sck)
its true?
and i dont see Soft_Spi_Init, only
Soft_Spi_Config ??

SOFT_SPI_PRESCALER_256, SOFT_SPI_LO_2_HI_IDLE_LO, SOFT_SPI_MODE_8

These are the parameters for the SPI communication. After compiling your project, select the parameter and use Ctrl+Space to see all of the constants available or Ctrl+Shift+Space to see the description of the parameter. Here 's the list of the constants you will find that way:

Code: Select all

  SOFT_SPI_HI_2_LO_IDLE_HI = 0;
  SOFT_SPI_HI_2_LO_IDLE_LO = 1;
  SOFT_SPI_LO_2_HI_IDLE_HI = 2;
  SOFT_SPI_LO_2_HI_IDLE_LO = 3;

  SOFT_SPI_PRESCALER_2   = 1;
  SOFT_SPI_PRESCALER_4   = 2;
  SOFT_SPI_PRESCALER_8   = 3;
  SOFT_SPI_PRESCALER_16  = 4;
  SOFT_SPI_PRESCALER_32  = 5;
  SOFT_SPI_PRESCALER_64  = 6;
  SOFT_SPI_PRESCALER_128 = 7;
  SOFT_SPI_PRESCALER_256 = 8;

  SOFT_SPI_MODE_8  = 8;
  SOFT_SPI_MODE_16 = 16;

The library configures SPI to master mode, so MISO (Master In Slave Output) is the same as SDI and MOSI (Master Output Slave In) is the same as SDO.
