Thanks. This seems like a much simpler way to set this up. All pins are configured as inputs including the LED? What are the actual `pinMode()` calls for this? >...

That looks like a proposed example sketch?
Thanks. Good catch. Want to PR an update?
Maybe? The current base class is fairly specific to the push/pull variant registers. The differences seem small, but may require some more refactoring.
FWIW, the CircuitPython library apparently "just works" with the caveat of needing to explicitly enable pull ups: https://github.com/adafruit/Adafruit_CircuitPython_MCP230xx/issues/54

Asking the GPS module manufacturer for clarification. The datasheet says this in section 1.9.2.1: > The host can then wake up the module from Standby mode to Full Power mode...
Recreated behavior using a QT PY M0 with GPS module attached via STEMMA connector. **Test Sketch:** ```cpp #include Adafruit_GPS GPS(&Wire); void setup() { Serial.begin(115200); while (!Serial); Serial.println("Adafruit I2C GPS library...
