Good.

However I have to say if you want speed use the spi_read and spi_write.

I will bear that in mind for the future. In this particular project, speed isn't that much of a major limitation, ...

Dang frustating to say the least.
Mighty happy you're 'up and running' though !! Got ANY hair left ??

My hair is rapidly dissapearing, soon I will have more forehead than humpty dumpty. I would n ...

So I think I have found the issue, it has taken many hours but hopefully this helps somebody else in the future.

#use spi(SLAVE, FORCE_HW, ENABLE=PIN_B0, SPI1, BITS=8, stream=SPI_STREAM,) ...

This is a great find, and I really seriously appreciate you trying it out.

Unfortunately (if I have understood correctly) even with this implemented it still doesn't work.

I had a look at the da ...

I forgot to mention earlier that I also did try the suggestion about the primary/secondary prescale.

I tried running:
#use delay(clock=40M, crystal=20M)

It makes no difference. Slave se ...

I then tried a bit of a hack, more as a sense check than anything else. Back to using SPI1, I just ran a pair of while loops continuously checking the status of the SS pin. When its high it just disab ...

1) Use the stream name in your spi_xfer.
2) You don't need the clear_interrupt in the ISR, the compiler does this
automatically.
3) Your clear_interrupt after enabling the interrupt is again poin ...

First of all thank you all for your suggestions. It really is appreciated.

First, check the FRMEN bit. If this is enabled, SSEN does not work.
Then check the ANSEL registers. All the SPI bits have ...

I'm having some issues with SPI on the DSPIC33EV256GM102, specifically slave select.

I have two DSPIC33EV256GM102's connected to a PIC18F as slaves, with the 18F as master.

A single master and ...
