BQ76PL455EVM-GUI-SW: BQ76PL455A-Q1

Part Number: BQ76PL455EVM-GUI-SW
Other Parts Discussed in Thread: BQ76PL455EVM

Hi,

I am Using BQ76PL455EVM-GUI-SW to evaluate the BQ76PL455EVM. I am able to see all the faults like (UV, OV, etc.) in GUI. But my question is:

Q- If I am observing a UV fault in the GUI, how can I use GPIO to turn HIGH on occurrence of the fault?

I want to use GPIO as output of the faults occurring.

Anyone who has worked on it, is requested to help me out.

thanks

Ritul

    Fault pin to flag fault conditions not GPIO.
    There is no setting in the GUI or device to have GPIO to flag fault condition.

    Why do you want to do that?
    You already have FAULT pin already

    The sample software code for BQ76PL455EVM says that Hexadecimal code to configure the board.
    Now, if I want to connect a Micro controller MSP430 and program it. Can I use Embedded C for configuring and programming the BMS EVM?
    If yes, can I get a sample code for it?

    Yes, you can use C to program  an MCU. Typically we use something like the TMS570 or the C2000, since they are made for similar applications as the bq76PL455. If you download the example code (found on this page:www.ti.com/.../toolssoftware ), this gives an example API that can be used to  communicate with the PL455. Just please be aware that the example code is not a functional demo, and only demonstrates the API. The software design reference actually walks through this code.

    If you use this API, the example code was made with the TMS570. If you port it to the MSP430, C2000, or other MCU you will need to configure  the underlying MCU registers appropriately.
