AFE10004EVM: Remote Temp Sense Selection

Part Number: AFE10004EVM

I am working with the AFE10004EVM board and software to read a remote temperature sensor but am running into a few issues with what I think is the software but could be the hardware. When I'm in the software and try to switch over the sensor for DAC drop down to remote but it will not let me save or enable the LUT without switching back to the local temp. Is there anything specific I need to do for setup to allow the remote sense to be selected? Also, could there be something I hooked up or jumped incorrectly on the board that would be not allowing this to be selected?

    Hi Christopher,

    After testing it on my own setup, it looks like it's a software error. It looks like the GUI resets when the Enable/Disable LUT button is press, or if you change tabs. It looks like the correct bit still writes to the AFE, though.

    To confirm that the correct bits are written for remote temperature, you can go to the Low Level Configuration tab and read the LUT Configuration Register (Register 0x0A). Some info on the bits in this register:
    LUTDIS is 0 when the LUT is on, and 1 when the LUT is off.
    LUTSEL1 / 2 is the selection for which temperature sensor is being used for each LUT. 0 = Local, 1 = Remote.

    If you read back this register after setting the Remote Temperature Sensor and the LUT Enable/Disable, you can see if the bits have been properly written. 

    Thank you for bringing this bug to our attention, we'll push an update to My Secure Software to fix it.

    Thanks,
    Erin
