    BNO055 Application board connection issue

    BNO055 Application board connection issue

    Hi guys,

     

    I want to connect "CJMCU-055(BNO055 Board)" to "Bno055 Application board 2.0" and use "DD 2.0(Development Desktop 2.0)".
     
     
    I connected VDD, VDDIO, GND, PS0, PS1, ADR_SEL, SCL, SDA of "Shuttle board or CJMCU-055" to Application board, 
    and connected "COD_GND, COD1, COD2, AMUX, AX, AY, AZ >> GND",  "COD0, COD3, COD4 >> VDD", and tested it
     
    1) BNO055 Application board + BNO055 Shuttle board -> DD 2.0 access OK, config mode -> ndof mode OK, sensor value output OK
    2) BNO055 Application board + CJMCU-055 -> DD 2.0 access OK, *config mode -> ndof mode NOK, *sensor value output NOK
     
    I checked pin of Shuttle board and CJMCU-055 with Logic Analyzer, but I could see that reset of CJMCU-055 to LOW.

    channel 1 : SCL, channel 2 : SDA, channel 3 : Reset

     

    Can you help me why reset is Low and how DD 2.0 can be used to CJMCU-055?
    (+ CJMCU-055 is OK in Arduino example)
     
     
    Thank you.

    Hello Jang_1,

    Every shuttle board had a shuttle ID as some pins of the 32 pin socket are set to the default level.

    After power on, DD2.00 identifies the shuttle ID according to the level of the pins.

    Your board can't be used directly in DD2.0. It is recommended that you buy shuttle board and use it with DD2.0.
