BQ79616EVM-021: BQ79616EVM-021

Part Number: BQ79616EVM-021
Other Parts Discussed in Thread: BQ79616-Q1

we are  interfacing microcontroller to evaluation board through tx and rx pins on J3

connector what should be baud rate for cor sending auto addressing commands to bq79616-q

is 9600 ok ?

  • Hi Yogesh,

    The bq79616-Q1 device expects UART at 1Mbps per datasheet and software design recommendations app note.

    Regards,

    Taylor

  • we are sending following command sequence to bq79616-021 evaluation board

    at 100000 baud rate with 8 data bits parity none and one stop bit
