AFE4430 GUI + 3 diodes (OSRAM module)

Other Parts Discussed in Thread: AFE4403EVM, AFE4403

Hello.

Could anyone tell me is it possible to use 3 diodes while measuring pulsoxymetry in AFE4403EVM GUI application? I have SFH7050 module + AFE4430EVM board. All the time when I chose either Push-Pull Led Driver Mode or H-Bridge in TX stage tab and enable TX3 mode, one of the diodes is marked OFF. On the ADC measurements tab there is only charts for LED1 and LED2/3. I know that AFE4403 supports 3 diodes but the question is - does GUI application supports it also?

Mariusz,

The AFE4403 supports 3 LEDs, but only 2 at a time. You may choose between making LED2 or LED3 active.

Thanks Amy.

So I guess I'll have to manually program the chip and switch diodes during the measurement cycle. I had to be sure that I didn't miss anything on GUI.
