Other Parts Discussed in Thread: DAC70508
Hello all!
I am having a little trouble setting the output of the DAC70508 DAC.
I think i have everything set up correctly as far as MSB, LSB etc... The CS line and SPI is looking good on the logic analyzer... but the output of the DAC is not changing.
I am using the standard settings for all config registers, i simply do not send any config commands to the DAC except for sending a test command to try to set the output of DAC1 to zero... but it just stays at the same value.
I am sending
0x09 0x00 0x00
Register address 0x09 is DAC1, then all zeros to set the output as zero... But it doesnt change ...
logic analyzer and schematic below.
Is it imperative to set the gain register before starting communication?
With default settings should the DAC update its output when CS goes back to HIGH?
What am i missing?
