@NickMaddock Hi Nick, sorry that i do not have a direct answer to your question. I have a question about the Roller Unit and did not get any response from the M5 Team yet. But it should be easy to answer for your: Is the Position resolution in Position mode restricked to the encoders incremental resolution or interpolated to a finer level? I'm interested in the product but would like to use is for some kind of gimbal application (mirror steering). Therefore the resolution of the encoder might be too coarse. The datasheet of the sensor states 12bit for incremental output but 15 bit using the serial interface. Unfortunately the videos from the roller unit seem to show 12bit resolution. The question is: what is the minimal achievable setting resolution in position mode?

@ChrisFSB Any ideas here folks? Thx!

@Arn_8 Problem fixed ! Thanks !

@Elliptic3612 @matthewchan @SB12345 @sqbaczek We have fixed this problem, please wait for the next version of UiFlow2 firmware

@HappyUser is there a way to operate them bot? I'm using it with platformio so maybe is easier to achieve that micropython?

@kuriko Ohhhh, what a pity! Thanks

I was also struggling with drift and negative values. I also receive a traceback error when I invoke tare(). The function works, when I go in and edit the python code (removing the parathesis). I suggested an update to the GitHub. I found the miniscale.py definitions in the firmware uiflow-micropython project. It has more details on the implementation of object class. https://github.com/m5stack/uiflow-micropython/blob/master/m5stack/libs/unit/miniscale.py

Thanks a lot for the fast reply. Very helpful.

@teastain Thank you - I had misunderstood what the Z was for. Because on the ky040 the middle pin is for the "switch" functionality (i.e. pushing down on the encoder) I assumed it was for this. I realise now that I need to treat that as a button and take it off to a different pin, which I know how to do. Thanks for your help!

@anzolin have you chose the correct model macro? have you tried this userdemo: https://github.com/m5stack/UnitCamS3-UserDemo/tree/main

@PharkieB Here you go M5Dial v6.f3d

@tspycher AFAIK: this are very simple transmitter/receiver modules. No protocol, no encryption, no guarantee for transmit/receive the correct data. You have to make your own protocol and data integrity functions. Try to send something out from UART (not faster than 10kbps) and receive it on the other side. Be aware that disturbance could be possible as 433.92MHz is used in a wide range of applications like wireless thermometers, garage door opener, car keys, wireless doorbells, wireless power switches... As you get the raw pulses out of the receiver it should be possible to receive and decode data from e.g. the thermometer oder switches. There are several protocol descriptions in the web. If you want to send simple data from one to the other device, ESPnow could be the better option.

@armilke no way https://www.ti.com/product/ADS1115
