BQ76PL455A-Q1: BQ76PL455A-Q1

Part Number: BQ76PL455A-Q1

Hello TI Family,

I started a project to read cell voltages on the BQ76PL455A-Q1 using the ATMEGA2560 processor.

I chose UART as the communication structure. However, I encountered a problem: Although I send the correct data packets, I cannot get the cell voltages pack from BQ.

I writecode  Arduino based, I get errors in the code. I am sending data to UART but how can I check if BQ is receiving the data?

    Hello User,

    Thanks for choosing TI's AFE.

    Firstly, make sure 455 is correctly waken up by driving wakeup pin 0-1-0.

    Secondly, MCU should issue a complete command frame to 455 otherwise a communication clear should be issues to recover UART engine,

    if not, then 455 UART engine will not respond UART command sending any more from MCU.

    If you can provide schematic of 455 and how does MCU connect 455, it will be great.

    Here is reference command frame to get VREF2 value.1460.slva617a_bq76PL455A Software Design Reference.pdf

    Thanks!
