SparkFun Qwiic Single Relay

Notes

• Existing Driver

Tested on XRP, the driver appears to work fine with a single relay. Don't have any quad relays to test right now.

Examples need work. They're only written for quad relays, so it's not obvious how to use a single relay. The examples also redefine the I2C addresses that are already present in the library.

The library imports enum which is not included in MicroPython. However it looks like the library doesn't actually use it, so it's safe to remove.

Just discovered this uses a mix of 0-indexing and 1-indexing...

Turning relays on/off uses 1-indexing:

https://github.com/sparkfun/Qwiic_Relay_Py/blob/e9fa0b7f66f320fefd1ac4b1911118221b16b766/examples/qwiic_relay_ex1.py#L79-L82

Getting the state of each relay uses 0-indexing:

Edit: Grabbed a quad relay and tested. Looks like the example is the problem, the state functions actually require 1-indexing. I don't like it, but it's consistent with the markings on the board, so will update to use 1-indexing.

Tested on XBee as well, all good!
