Hi @felmue and thanks. This helps a lot.

Hi @felmue and thank for you're quick respond

I was wondering about the framework. To the best of my understanding do I use the 1.8.19 framework. It is what the upper left corner tells at least. Should M5ez not work for me?

Do I have to reinstall Arduino IDE to "downgrade" to a framework that works?

Thanks again for you're time

Hi, I am a relative beginner to arduino, M5Stack and M5ez. I was trying to use M5ez in a test project however if I use #include <M5ez.h> then the sketch won't compile. Even the basic Hellow_World example included with the M5ez won't compile for me.

I have follow all steps in https://github.com/M5ez/M5ez
and installed both M5ez and ezTime library
I have selected the correct board.

Now, I turn to you, the masters of M5ez. What did I do wrong?

Hi @felmue and thanks for the help. I changed GPIO and it works now. Strange as input port 2 worked when the temperature sensor were implemented separably.

However I have spend enough time trying to make it work. So I will not conplain now that it is working.

Thanks again

EricR

Hi and thanks for you're time

I am a relative beginner to M5Stack and have made 2 test programs. One that displays weekday, date and time and one that use a Dallas 18B2D temperature sensor to display the room temperature. Both works interdependent.

However a strange interaction between the two setups occur when I try to implement them both on the same time.

If the sensor is connected to M5Stack during start up, then the internet setup won't connect, resulting in the weekday, date and time not working but the sensor value is displayed correctly.

If the sensor is disconnected from M5Stack during start up, then the internet setup will connect and weekday, date and time displays... But the sensor will not setup correctly and the sensor value is not displayed correctly.

I can't find the reason why the internet setup wont work when an analog input is connected to my M5Stack. Do you, masters of the M5Stack have any idea what could be the cause?
