Hello,
I am having some trouble setting up the AD9910/PCBZ evaluation board via external control from an Atmel XMEGA. I think my main problem is the IO update. I would like to use the automatic IO update so that I don't have to rely on an external signal on the line to sync command. Any help with control register setup and wiring would be appreciated. I have the xmega SPI pins setup correctly (as far as I know). I removed jumpers W5, W6, and W3 and changed W1, W2, and W4 to disable. Below are the commands I have sent.
CFR1 = {0x00, 0x00, 0x00, 0x00, 0x00};
CFR2 = {0x01, 0x00, 0xC0, 0x08, 0x20};
CFR3 = {0x02, 0x1C, 0x3F, 0x41, 0x18};
SingleToneProfile_1 = {0x0E, 0x08, 0xB5, 0x00, 0x00, 0x00, 0x07, 0x7F, 0x27};
Thanks.
