Catherine,
Thank you for the suggestions again. I'm writing 8 bits at a time, which is 4 bytes for each instruction. Doesn't this mean that I'm writing 8-bit words?
We had it set for that low frequency for an accelerometer that we were using previously. What frequency would you suggest I use for the SCLK? The uProc can only send either 8-bit or 16-bit words. Thank you.
Yes, I verified that the IOVDD and AVDD measure 3.3V. I pulled up the PDb pin, and the signal looks much cleaner now, on the scope. I still can only see a 0x00002000 when I try to read one of the registers with 0x20, 0x21, 0x22, 0x23, 0x24 etc or 0x30, but only 0x00000000 when I try to read the 0x01 -0x0F. Any idea why that is?
