SPI Write is breaking my head!

Hi all! I got a device conected at the SPI port.

At the same register the transfer() function in READ mode returns all the default values from the device.

At the device PDF saids that the address's D7 bit is the RW control. So i only do a OR with a variable with that bit in true.

But nothing happends...suggestions?

Best Regards Frank

What an amazing coincidence. I too have a device connected to the SPI port.
