| #use spi (FORCE_HW on dspic33F devices |

Hi All
I have used
| Code: |
#use spi(FORCE_HW, BITS =8,stream=multi_spi)
|
in the other 8 bit devices successfully but I am not able to compile this option on dspic33F.
I have use the following code:
| Code: |
#pin_select SDO1 = PIN_B13
#pin_select SDI1 = PIN_B11
#pin_select SCK1IN = PIN_B10
#use spi(FORCE_HW, BITS =8,stream=multi_spi)
|
How can I force CCS to use the hardware spi (not software spi) to perform the spi transfers?
Thank you |

I'm using:
| Code: | | #use spi(MASTER, SPI2, STREAM=VIDEO, mode=0, BITS=8) |
just fine EXCEPT that barely PCD pre-4.100, transfers with spi_xfer() didn't work quite right - so I had to do them by hand.
You are using PCD, right?
What version are you at?
