| #use SPI issue on PIC16F18855 |

Anyone see why the two lines below would generate a compiler (PCWH 5.088) error for a PIC16F18855 ? Thanks!
| Code: |
#use SPI(SPI1, MODE = 0, BITS = 8, STREAM = Encoder_SPI)
#use SPI(SPI2, MODE = 0, BITS = 8, STREAM = DDS_SPI)

*** Error 99 "J:\AAA_PROJECTS\CCT 70K2 DDS PTO\C Code\70K2_DDS.h" Line 12(5,57): Option invalid Not valid for H/W
*** Error 99 "J:\AAA_PROJECTS\CCT 70K2 DDS PTO\C Code\70K2_DDS.h" Line 13(5,53): Option invalid Not valid for H/W |

Have you got #PIN_SELECT statements for the SPI pins?.
Needed. The comipiler does not know about the 'default' selections. |

It's one of those things where the manual could definitely be 'improved'...
The PIN_SELECT 'sticky' here in the forum may help. 
Have fun. |
