[SOLVED] Using SS in #USE SPI

How do I map the SS in the following code:

Code:

#pin_select SCK1IN=PIN_B4
#pin_select SDI1=PIN_B6
#pin_select SDO1=PIN_B5
#use spi(SLAVE, SPI1, MODE=3, BITS=8, ENABLE=PIN_B7, stream=SPI_PORT1)

or do I have to use setup_spi and what are the name of the SS pin for pin _select then.

The compiler gives an "Option invalid Wrong SS pin" error.

Regards

Remove the enable option and put in a pin_select for the SS: SS1IN=PIN_B7

Thanks jeremiah. That solved it, but I had to keep the ENABLE OPTION, for the compiler to set the register for SS. Regards Alan
