Lol of course not  . I've done so many changes trying to make this work that it's hard to find a file with correct code any more. Sorry for that. I don't even remember the reason why I switched to sp ... |

| I have too tried pins D1, D2, D3, G8, G7 with no luck (no compiler errors). I don't believe its a pin problem as pps works fine with the serial port. Also I've tried manually setting I/O direction. ... | |

| The loopback test failed as well. I still get zeros. And I've tried different pins too. :(
FvM could the fact that I'm using the internal osc have anything to do with it? Doesn't sound likely but I ... |

| But, you see the accelerometer is responding, so if it's a hardware issue it must be PIC's
The loopback is a very good idea! |

| What's going wrong then? It's driving me mad. Why doesn't it read a perfectly sent response? I really don't want to switch back to C30! I hate c30! | |

Thank you for your reply. Could you please clarify for me the following; What exactly SPI_CPHA_0 is doing? How did you find out that RPI45 was not working with pin_select? Did you get an ... |

I just happened to name my c file spi so spi.h was the file generated by the wizard. The reason I am used two spi_read is that if I tried with one write and one read (as it would be th ... |

| Are you working with an accelerometer too? I actually need to implement two spis (like one was not enough); one between the accelerometer and the gb106 one between the gb106 and another pic.

| Thank you.
In the meanwhile could you please post the version of your code that writes directly to the control registers to give it a go? cheers |
