mikoPascal PRO for dsPIC30/33 and PIC24
MikroElektronika
Requires Global variables:
- CanSpi_CS: Chip Select line
- CanSpi_Rst: Reset line
- CanSpi_CS_Direction: Direction of the Chip Select pin
- CanSpi_Rst_Direction: Direction of the Reset pin
must be dened before using this function.
The CANSPI routines are supported only by MCUs with the SPI module.
The SPI module needs to be initialized. See the SPIx_Init and SPIx_Init_Advanced routines.
MCU has to be properly connected to mikroElektronika’s CANSPI Extra Board or similar hardware.
See connection example at the bottom of this page.
Example
// CANSPI module connections
var CanSpi_CS : sbit at LATF0_bit;
CanSpi_CS_Direction : sbit at TRISF0_bit;
CanSpi_Rst : sbit at LATF1_bit;
CanSpi_Rst_Direction : sbit at TRISF1_bit;
// End CANSPI module connections
var CANSPI_Init_Flags: word;
...
CANSPI_Init_Flags := _CANSPI_CONFIG_SAMPLE_THRICE and
_CANSPI_CONFIG_PHSEG2_PRG_ON and
_CANSPI_CONFIG_STD_MSG and
_CANSPI_CONFIG_DBL_BUFFER_ON and
_CANSPI_CONFIG_VALID_XTD_MSG and
_CANSPI_CONFIG_LINE_FILTER_OFF;
...
SPI1_Init(); // initialize SPI1 module
CANSPIInit(1,3,3,3,1,CANSPI_Init_Flags); // initialize CANSPI
Notes - CANSPI mode NORMAL will be set on exit.
