AFE4403EVM: AFE4403EVM Configuration for 3 LEDs

Part Number: AFE4403EVM

Hi,

Good day.

Our customer is trying to configure the AFE4403EVM with the SFH7050 sensor to read from the three LEDs (red, infrared, and green)
Can you please help with the configuration? The manual that comes with board only tells how to configure two LEDs..

Looking forward to your advise.


Regards,

Cedrick

    Hello Cedrick,

    The third LED can be selected  by enabling TX3 mode in the TX Stage tab. Refer to section 9 in the user guide for configuring the Osram SFH7050 sensor board for push-pull or common anode configuration.  

    Please note that the support for the third LED is a static mode selection as opposed to dynamic switching selection. The device does not support simultaneous 3 LED operation.
