Re: float conversion

Did you rule out a hardware issue? I do not want to underestimate you, because we do not know eachother (yet) I might be asking silly questions. I was thinking maybe you do not have sufficiently low pullup resistors. Or a 5 V - 3.3 V conversion issue. Does your library check the I2C ACK? If it does ...

Re: Sleeping Z-Uno - Power consumption

Ah, the EEPROM, thanks for bringing that up. I see, so the usable range is 2.8 - 3.6 V. If someone wants to charge a cell in-circuit, you would have to do something to limit the upper voltage... Maybe use a low quiescent regulator, like XC6206 or equivalent.

Re: Z-UNO blocked after several hours of operation

I see. So you think the issue was introduced by upgrading the framework? I do not know how to test that hypothesis... In that case maybe other user have similar problems. Let us wait and see...

Re: Z-UNO blocked after several hours of operation

Fair enough! So when you connect pin 17 to ground, the green led stops blinking if you leave it powered for about one day?

If you exclude the Z-Uno, and ground that pin, does it still crash within a day?

What happens if you remove the oled code?

Re: Z-UNO blocked after several hours of operation

I've loaded your scene. No sensor or OLED attached. So it reports -327.67 °C as I expected, but that is not the issue here... The main thing is that the green LED keeps blinking, it does not crash... Another thing is that your interrupt routine violates a requirement mentioned on the reference pages...

Re: Z-UNO blocked after several hours of operation

Thank you for sharing your code. I am convinced that sharing code is always interesting, for educational purposes! I'll run your code on my Z-Uno and see if I can find something. At the moment, after a quick look, I'd say the green LED stops blinking if your code hangs in loop() or getter(). The onl...

Re: Z-UNO blocked after several hours of operation

I run a BH1750 sketch (an improved version of the version published on the forum) and it does not crash. It runs until I reboot the Z-Uno or change the sketch. The longest time between 2 reboots was about 24 hours.

If you could share your code, I'll see if I can find anything suspicious...

Re: Sleeping Z-Uno - Power consumption

The ZM5101 module on the Z-Uno requires a power supply 2.3-3.6V (reported on te spec sheet of this module). Usually a 3.3 V CMOS chip can survive a higher voltage for a short time, but it is not supposed to operate at higher voltages. Conclusion: this module can operate from any primary lithium cell...

No Arduino menu on OSX High Sierra: set language to English-US

Java based programs sometimes do not display a menu when running OSX High Sierra and your language is not English. Arduino is based on Java. The fastest workaround is to set your Mac to use English - US. After a reboot you can run Arduino 1.6.5 to program your Z-Uno. https://github.com/arduino/Ardui...

(...)We will soon release 2.1.1 with many internal changes
Thanks! That is good news. If you have a pre-release, I'll be happy to test it (BH1750 enhanced sketch, Neopixel 21-25 LED issue, FLIRS test, ...).
