Hello, I am a newcomer to the motorola chips. i have a DSP56F826EVM and am trying to get the SPI port to write. My code is based on an example (5.1) in the codewarrior documentation. #include "port.h" #include "io.h" #include "fcntl.h" #include "bsp.h" #include "spi.h" void main (void) { spi_sParams SpiParams; int SPIMaster; UWord16 Data = 0x1234; int i; SpiParams.bSetAsMaster = 1; SPIMaster = open(BSP_DEVICE_NAME_SPI_0, 0, &SpiParams); for(i=0;i<500;i++) { write(SPIMaster, &Data, sizeof(Data)); } close(SPIMaster); } My problem is that whenever open() is called, it completes (it does not return a -1) so it completes successfully. however, when it exits, the entire program finishes, the for loop is skipped, the close () function is skipped, it just goes to the closing bracket and stays there. can anyone help?? thanks a lot |
