Thank you for reporting back! Great to see you are using a HC too ;-) For what it is worth: I think printing the temperature like that is a good workaround! Now this is solved... Did you say need an Arduino because the Z-Uno cannot send 288 IR codes? I think I have read somewhere that the IR buffer ...

Thank you for confirming our suspicion. As user schmidmi pointed out, he has "worked around the problem" and this is his topic, but I am still interested in one more thing... As you say, disabling interrupts might fix the issue... I wonder, what is the impact on the operation of the Z-Uno. For insta...

Under 2.1.1 I can compile one time. The next time I compile, I get: "?ASlink-Warning-Undefined Global '_Timer' referenced by module 'LLCore_arduino" I can make it work by applying this dirty hack: I add "extern void Timer();" to the source code, like this: extern void Timer(); // Makes linker happy ...

On my Mac I can compile and upload both under Arduino 1.6.5 and 1.8.5, so I definitely have an issue on my Windows laptop.

I have a specific issue with my BH1750 sketch, I'll post the details in that topic:

viewtopic.php?f=3427&t=25521

Any sketch seems to end in the same error: ERROR [2017-10-02 09:34:20,589] [Errno 22] invalid mode ('w') or filename: '\\C:\\Users\\peter\\AppData\\Local\\Temp\\arduino_build_582937Custom.ast' I guess a \\ is missing between "arduino_build_582937" (the build directory) and "Custom.ast" For instance,...

@coco82 I recognize that type of display, I "bitbang" it on my arduino :-) Regarding injecting current into the pin of a microprocessor, if it is high enough the chip might latch-up and get destroyed. I have a certain Microchip mcu, and if you inject 1 mA on a digital pin then the ADC gets less accu...

I agree... I have been delving in the source code of the Wire, ZUNO_OneWire and ZUNO_OLED_I2C libraries and lst files and it has not become any clearer to me. :? I'll try again later. Maybe it is a stack issue like you said and in that case it might be worth waiting for firmware 2.1.1 because that w...

New observation: if you convert to int, the sketch does not crash. But I only let it run for one minute, the test time is a bit short oled.print(int(counter)); conversion to long and doing math does not crash it within one minute either: oled.print(long(counter*1000)); But printing a float with 0 pr...

Thanks, your information is helpful. Together we will solve this mistery! ;-) I think I have made some progress. I reduced the code and now it crashes randomly in less than 1 minute. Tell me what you think... // OLED test by petergebruers, based on DS18B20 sketch // by Michael Schmidt #include <ZUNO...

I am running this sketch right now, I want to share it so you do not have to run the same test as me. I do not see any flickering. I wonder if it makes a difference if you put zunoSendReport after the oled update... My minimalistic sketch does not have zunoSendReport right now, I'll add it if this t...
