I’m using an ADPD188GG with both photodiodes summed and connected to channel 1 (as in figure 16 of the data sheet), which works well. I would like experiment with reading the two PDs separately off channel 3 and 4 (as in figure 15), but can’t get that working. Does someone have a resource for the registry values that might get this to work or a .dcfg file that does this? I suspect I’m overlooking something in my values. I’m currently doing this testing on the eval board and the included software – though we may eventually move to our own hardware.
