ARghH....

Having played endlessly with pin congfurations on several of my DSP PCBs (both previously working fine) and 4 different versions of SigmaStudio, I have managed to get the SPI_MOSI to do it's thing with data to the EEPROM, but it still doesn't work properly.

No idea. Answers on a postcard please....

I shall dig out my original test rig that is in my wardrobe and if that doesn't work; having not been used for a year since it worked flawlessly; then I give up!
