Adafruit I2C Stemma QT Rotary Encoder/Quad Rotary Encoder Breakout

Adding support for Adafruit I2C Stemma QT Rotary Encoder Breakout

Adding support for Adafruit I2C Stemma QT Rotary Encoder Breakout (4991).

Please describe your use case for this integration and alternatives you've tried:

• I would use the rotary encoder and NeoPixel on board connected with a Stemma QT cable.
• Using the three on-board address jumpers, I would connect up to 8 of these rotary encoders to a single I2C port. The first will be at address 0x36, the last at 0x3D when all three jumpers are soldered.

Additional context

The onboard microcontroller is programmed with our seesaw firmware and will track all pulses and pins for you and then save the incremental value for querying at any time over I2C.

• Arduino library: Adafruit_Seesaw
• I2C address: 0x36 to 0x3D

If it's running seesaw, you could try my seesaw component: https://github.com/ssieb/custom_components/tree/master/components/seesaw You will need to set the i2c address.

Thank you. I'll try to adapt it to my needs.

I was thinking it would work right away. You can find me on discord if you need help using it.

Thanks. For the encoder module, the I2C address is 0x36 but for yours: https://github.com/ssieb/custom_components/blob/master/components/seesaw/__init__.py#L31 ).extend(i2c.i2c_device_schema(0x49))

Was it for this module Adafruit ATSAMD09 Breakout with seesaw?

[ssieb]

You really should ask about this on discord. For any i2c device, you specify the address using address: 0x36. Put that on the top-level seesaw: component. That's why I said you would need to set it. Don't continue this here.

The problem I'm facing is that the seesaw component only supports a single encoder, whereas it is possible to have a chain of 8 encoders. So it can't work also with Adafruit I2C Quad Rotary Encoder Breakout with NeoPixel.

Using the three on-board address jumpers, you can connect up to 8 of these rotary encoders to a single I2C port. The first will be at address 0x36, the last at 0x3D when all three jumpers are soldered.

Would it be possible to have this type of configuration instead?

Here is a test config for Adafruit I2C Quad Rotary Encoder Breakout with NeoPixel - STEMMA QT / Qwiic, Product ID: 5752 :

These are the pin names in the seesaw firmware for each rotary encoder:

Encoder #0
  Switch: pin 12
  Encoder A: pin 8
  Encoder B: pin 9
Encoder #1
  Switch: pin 14
  Encoder A: pin 10
  Encoder B: pin 11
Encoder #2
  Switch: pin 17
  Encoder A: pin 2
  Encoder B: pin 3
Encoder #3
  Switch: pin 9
  Encoder A: pin 4
  Encoder B: pin 5

I created this error : [pin] is an invalid option for [binary_sensor.seesaw] #72 to try and find out how to correct it.
