LTC5594 - DC2465A and DC590B

Are you connecting to DC2645A through our DC590 or DC2026 controller? Please make sure the I/O voltage is set to 3.3V (JP6 on DC590, and JP3 on DC2026). Please also verify that jumpers are installed on JP1 and JP3 on DC2645A. Manuals for the 3 evaluation boards are linked below:

Hi Shsiao

Thank you for your anwser.

Yes i have verified the i/o voltage on 3,3V.and the jumper on DC2645A are at the right position.

I have allready all documentation.

i have and spi connection with linduino board, but i can't used the demo soft for ltc5599 because the bit r/w was not at the same place (MSB for one and LSB for the other device). i have writing an little and simple soft with arduino SPI librairie.

But now, i must working for few day's on another project and , i think i will doing the first test next week. 

regards.
