Other Parts Discussed in Thread: DAC81408, AM2634
Tool/software:
Hi,
I have got a DAC81408EVM, and I try to control it by the SPI from my Arduino.
Here's my setting
VCC = 10V
VSS = 0V
VDD/VAA and VIO is 5V (J10 selection = VIO)
1. I have tried to read 0x03 and I can get the correct value 0x0A24
2. following initial process
Write SPI_CONFIG(0x03) 0x0A84
Write DEV_PWDOWN(0x09) 0xF00F
Write GENCONFIG(0x04). 0x7F00
3. Write DAC0(0x14) 0x00FF
but the output(measure at R6) is still 0V
I also read each register after I program it. I found that 0x04 becomes 0x0400. Is it correct?
I read similar question in old thread, but discussion moved to mail.
best,
Daniel
