I have a library I wrote. The API is different: https://github.com/dhalbert/CircuitPython_LCD. There are two branches available: master and minimal. The latter has a lot of functionality removed: I needed it to make it fit on a SAMD21.

Is it an Adafruit backpack? There are different kinds of I2C backpacks with different protocols. The Adafruit backpack uses an MCP23008. Common cheap backpacks use a PCF8574.

Ah that would be it. It's a generic from the local electronic store. PCF8574T chip on the back. Are drivers available for that chip? I can't see it in the library bundle.
