FAQ: When I use an I2C device, I'm getting a i2c_writeBufferRaw: symbol not found error

  • administrators

    If you're using an I2C device and you're getting a message saying i2c_writeBufferRaw: symbol not found
    Don't panic, it's a very easy fix.

    All that's wrong is that your I2C library is out of date and does not have a specific function that allows I2C writes without specifying an address. To update your I2C library, run following commands:

    opkg update
    opkg upgrade libonioni2c pyOnionI2C
