Does anyone have a LabVIEW GUI for the ADAR1000 they would be willing to share? First time trying to program a chip via SPI and have not gotten anything to work. Any help would be greatly appreciated. Thanks.
Sort of. I was able to get it to output some commands on the daisy chain SPI output (P3), but when I tried to read specific registers it was just reading back FF for every one. I will post the waveforms I am sending over the P6 pinout later today to see what you think.
The timing diagrams are not consistent in the datasheet so I am not sure as to which SPI scheme I should be using. However, I decided to try all of them and still nothing worked. Here are my waveforms for Clk pol = 0 and Cpha = 0. These commands still didn't result in a read back with the other three combinations.
I followed your command instructions from my last post
Write 0x00 81
Write 0x00 3C
