Hello @Rusticus42

there is a solution: use a M5PbHub unit (which is an I2C unit) to read the button states of the Dual Button unit.

I created an example in the UIFlow2 Project Zone: M5AtomS3_RFID_PbHub_DualButton_Test_UIFlow2.3.7

Note: I do not have an M5AtomS3R so you probably need to adapt the example.

Thanks
Felix

You gotta push the download button to permanetly flash the code to the device:

Hello @Rusticus42

yes, it is possible to connect more than one I2C unit. However Dual Button unit is not an I2C unit. You can see that from the color of the connector.

• I2C units have a red connector
• I/O units have a black connector
• UART units have a blue connector

The connector on AtomS3R is white which meas it can be setup for I2C, I/O or UART mode, but only one at the time.

Thanks
Felix

What did you mean by nothing works?
This is a firmware for testing AtomS3R+Atomic Echo Base: https://drive.google.com/file/d/1WpkKjaky1qSQvfkpKsOvaeMFO-Kb1zPO/view?usp=drive_link

Hello @vsambur

I don't think this is supported (yet). See here.

Thanks

Hello @MCU1536

assuming you are using Arduino and the M5StamPLC library then it is clear as to why the date and time are not retained. There is no code in the M5StamPLC library to enable charging the RTC backup battery.

I created a PR which enables RTC backup battery charging.

Thanks

Hi! Could you please provide us your result for us to check?

EZData 2.0 for UiFlow2 is now on maintaining, we're adding exciting new features. Stay tuned!

Using this example is fine.

Hello @RPI25

hmm, I am afraid I am out of ideas, sorry.

Edit: BTW: I now tested with both, M5Core2 (original) and M5Core2 v1.1. RGB LED on port A work with both of them.

Thanks
Felix
