Hi,
I'm using the ADPD 1080 on own custom board, but utilize the microcontroller board that the interfaces with the wave tool software. For my application, I'm trying to make a measurement of oxygenation across a tube of blood (hence a transmission measurement) using two LEDs (one red one IR) and a large pin photodiode (1cm^2). I have gotten the board to communicate with the software and have attempting the make measurements of the light intensity for the leds and the configured the software such that each LED is in its own time slot. When I try to make a background measurement (no LED light), I keep seeing that the ADC output is larger than when the LEDs are turned on. I thought it could be a saturation but the problem still occurs even when I place the board in a black box. Is there an issue with my register settings below? Any help would be appreciated.
Thank you,
Osama
