8-Angle Unit does not respond to read_status call through I2C



  • My 8-Angle Unit only responds to I2C communication for register addresses 0xFE (Version) and 0xFF (Address) with values “1” and “0x43” respectively.
    “read_status” calls to all the other register addresses (0x00 – 0x17, 0x20, 0x30 – 0x53) respond “None”.

    Please help me to read values from 8-Angle unit.

    Output from my test python script as well as the script:

    from unit8angle_read_status import *

  • Additional information:
    I am using ATOM Lite to communicate with 8-angle and I flashed ATOM Lite with ATOM Lite firmware v1.11.0, by using M5Burner-v3-beta-win-x64.
    When I connect to ATOM through Terminal in UIFlow, it says “MicroPython 3a9581b5a-dirty on 2022-12-08; M5Stack with ESP32.”
    MicroPython on the ATOM Lite is perfectly working with other units, such as CardKBCardKB V1.1 (I2C) and ATOM GPS kit (UART).

    If anyone can give me valid MicroPython scripts to test the 8-angle unit response that I can try with my ATOM Lite, I would appreciate very much.
