connecting LMP91000 with the cc2541

Other Parts Discussed in Thread: LMP91000, CC2541

Hi there. Im trying to connect the LMP91000 potentiostat to the CC2541 for a blood sugar sensor response, using the IAR embedded workbench to debug the code and the Smart RF Flash programmer to flash the MCU. The example code SimpleBLEPeripheal code form TI is my point of origin, which is only an example, not containing the include for the LMP91000 unit. I want to include he code for the LMP91000 but I'm not sure how to do it in the IAR workbench. Any clues on how to approach this? 

Thanks for all help in advance!

    Brittan,

    I'd start with the TI design Gas Sensor Bluetooth Reference design http://www.ti.com/tool/gassensorevm.

    Best regards,

    Hi Matthew

    Thanks so much for your reply! In my question I forgot to write that I do use the gas sensor platform for my project. 

    Guess I was not being thorough when writing my question, I'm sorry about that. 

    However, my challenge is how to configure the LMP91000 with the right settings. I want to enable the temperature sensor on the LMP to check if I can get a readout and to do some noise cancelling in the circuit. As long as the temp sensor is not enabled I got a readout from the transamplifier and from the vref. But when Im enabling the temp sensor I cant get a readout from the temp sensor. 

    Any thoughts? 

    Thanks in advance!!

    Best regards

    To simplify:
    I want to connect a 3-electrode sensor to the lmp91000 and connect to the cc2541, sending the output via bluetooth to the gas sensor app. I use the iar workbench 30-day trial. The code is executed, the app graph timeline is posting, but there is no readout from the sensor. And I suspect the lmp91000 is not configured right.
    Any thoughts of where in the software code I can configure this?
