Hi,
Is the code you are showing the only initialization commands you are doing for the device?
Can you capture the SPI communication on an oscilloscope or logic analyzer? Usually, this is an issue with incorrect formating of the SPI command.
Thanks,
Paul
Hello,
Were you able to try out Paul's suggestions? Did you confirm if the DAC was first configured through the control register (addr 0x55) before attempting to write to the DAC data register?
