Hi @suba83
You might need to specify more details on this, for example:

  • How you setup the physical connection between VIM1 and the device over I2C?
  • How you setup the software/driver to let the device work out?

Good day!

Hellow, i use open source Home Assistant for smart home und i need connect MCP23017 I/O Expander to Khadas VIM1. It’s standart integration. I connect MCP23017 to I2C und has detect it. But mcp23017 implementation depends upon and external adafruit-circuitpython-mcp230xx package that depends itself upon Adafruit_Blinka package that includes the board module. Khadas doesn’t support.
I’d like add Khadas to support Adafruit_Blinka/

For me is very difficult.
