I don't believe setup_spi() is needed since I have a static configuration that does not need to be setup at runtime... although, I will try it.. It can't hurt.

I have some code that executes SPI commands based upon user input from the UART (so I can peek and poke at a SPI device from Windows Hyperterm). The problem is that reads always read "FF". ... |

setup_spi() was not used but rather..
#use spi(MASTER, MODE=1, FORCE_HW, BAUD=1000000, BITS=8, stream=SPI_STREAM)

Is there a clear screen funtion(clrscr) for the CCS compiler?
If you want to "clear screen" when on a RS-232 UART port. Just print a "form feed"
printf("\f"); |

In the following code snipet, the 2nd SPI write hangs everytime. What in the spi_write routine might cause this? Something I'm doing?
Thx.

BYTE address;
BYTE value;
