The question about the OLED libraries still stand howiever. Where are these .h files located?
located in the lib directory - as sample at Windows:
C:\Users\[user name]\AppData\Local\Arduino15\packages\Z-Uno\hardware\zw8051\2.1.5\libraries\ZUNO_OLED_I2C\

Re: SSD1306 library/OLED screen

I can't get my oled to work. It should work - without problem. You are sure that you have SSD1306 controller on display? Some boards are working with SH1106 chip. I have got the same "wrong"... If SH1106 - checkk my lib, it is working but need 1024bytes of RAM (because needed buffer usage) Wired - ...

Re: OLED 128x32 - library modification?

Hi, attached my modified lib with sample sketch. Use oled.begin(32) for the 128x32 pixel OLED. There are no major changes in the lib - only the fillRect() function and parameter settings were modified. For 128x64 oled.begin() or oled.begin(64) can be used. @PoltoS: the update you told of the Arduino...

OLED 128x64 lib for SH1106 chip for testing

Hi, I have got a "wrong" sample of the 128x64 I2C OLED display with an other chip (SH1106 instead of SSD1306). So I had to make a new lib for it - maybe somebody else can need it ;) Major difference - this chip can not address the lines directly and will not receive all bytes for a line. So the only...

Re: Reported values got stuck sometimes

Have you a chance to make a log file?
I mean from Z-Uno - with Serial.print as sample to log the reported values (in the getter procedure - and maybe at other place before).
Only to be sure that here is all ok.

Re: Library for CCS811 CO2/VOC sensor for testing.

I just have tested the different modes and they are working fine. If you change the sample sketch - please note about the requirements (regarding documentation) When a sensor operating mode is changed to a new mode with a lower sample rate (e.g. from Mode 1 to Mode 3), it should be placed in Mode 0 ...

Re: Reported values got stuck sometimes

Why you need polling at all?
The sensor (Z-Uno) will send the values to the HC2 - this is enough, right? In best case the sensor will send values only if a value was changed, or after any defined time (for the case that not changes). This will optimize the network traffic.

Re: Reported values got stuck sometimes

Try to send every 5 minutes an average value - and reduce the polling time - and check it .....
