I made some investigations during the WE. The problem is caused by using the ZUNO_OLED_I2C library. If I don't use it, everything is working very well. In my device I want to display the temperature on a local OLED-display like shown in the ZUNO examples. This works, but a some hours the Z-UNO is bl...

Nice ideas.
But my problem is, that the code was working for days and days without any problems with the firmware 1.8.
And now with 2.1 I got this issue.
Strange....

Thank you for all your help.
But my problem ist not the interrupt or something.
The interrupt is used by a push button to switch my A/C device on or off. For the sketch it means, it's used nearly never.
But the Z-UNO hangs just processing the loop Methode without any influence from outside.

I don't think, that there is something strange in the code, because it was running several weeks without any problems under previous versions. But nevertheless, here it is: // Z-UNO used to connect a Mitsubishi A/C controller to Fibaro HC 2 // It provides the actual temperature and an ON/OFF switch....

I've created a sketch providing a temperature and a binary switch to my HC 2. In the first point of view everything seems to work smoothly. The temperature value is calculated via a DS18B20 which is read every 30 seconds. To my Z-UNO I've connected an OLED display which shows the temperature and the...

Hi! Today I had a look to the GPT sketch provided by you. In the fist Step I tried to find the missing modulation, and I found it. In your sketch there is a line which multiplies the value in the raw data by for. You have done this, because a tick of the GPT is 0.25 u seconds and the values in the r...

Thanks for your help!
At the moment I'm very busy also.
I will check it out later....

Thanks for the quick reply 8-) I don't know this word 'holidays' because I'm working as a freelancer. But of course I hope, you did enjoy yours... But back to IR: The length of marks and spaces are already described in the raw data variables in my code. But if it would help, here again a listing of ...

and by the way:
I failed also to use a 'normal' output for creating correct sequences

Hmmm, no reply is also a type of reply....
