BQ76PL455EVM: Is there any programmer technical document for BQ76PL455EVM module?

Part Number: BQ76PL455EVM

Hi. The BQ76PL455EVM module has a GUI version of control software, while, in my case, I need to code the commands by myself and sent through UART from a microcontroller (TMS570), is there any resources for programmer? The TI website only shares a simple sample code and a GUI user document, which is far not enough. For example, I maybe need to know some detailed internal software information of BQ76PL455EVM, so that I can access the register.

Thanks for any help.

    Hi Joe,

    The resource you are likely looking for is section 7.5 (command and response protocol) of the PL455 datasheet (datasheet link: www.ti.com/.../bq76pl455a.pdf). All of the UART communications with the PL455 will be based on reads and writes, as well as wake (and other) tones. The process of creating the UART frames is included in this section, and can be used for all communications with the device. Section 8.3 of the datasheet provides an overview of the initialization process. These two together should provide a great starting place for developing UART communications for the PL455!

    Let me know if you have any other questions!

    Thanks,
    Vince

    Also, in case you haven't used this document yet, the "Software Design Reference" for the PL455 is a fantastic resource for starting with UART communications from a microcontroller. Here's the link: www.ti.com/.../bq76pl455a.pdf

    Really thanks for the great resources. And, I have no idea why TI don't put datasheet and technical document of devices on the selling page, like here, www.ti.com/.../BQ76PL455EVM . I always need to find it somewhere else, same story with the TMS570 launchpad. Or is there already a place just for downloading the TI datasheet?

    Glad we can help with the information needed.

    thanks for the suggestion to add navigational easiness inside each of the product folder. Will pass your recommendation to the Digital marketing group.
