Heatpump + remote controller

Edoardo Macrì

Hello,
happy xmas to all,
I'm Edoardo and I'm playing with MySensors a lot since the last year.
Today I decided to make a sensor that can turn on and off a heatpump from a relay (not implemented yet) with a remote controller with an 0.96" OLED I2C Display.
Since I was making the code to work without mysensors the display work showing the temperature (obtained by a bme280), controls and display work flawlessly, but when I implemented the MySensrors part the display was stuck and didn't show up the loading splash screen.
At the second attempt the Nano was rebooting itself (only on MySensors code).
Can anyone explain me what I'm doing wrong?

here are my sketches:

Useful data:
– Clone Arduino Nano
– MySensors Library 2.3.1
– Working NRF24L04+
– Working OLED Display

tsjoender

Perhaps the 3.3V voltage regulator on the Nano does not provide enough current to power both the radio module and the OLED display? You could test the setup first with the display disconnected. If that works then you can try and find a way to power the display from a different source.

bjacobse

Maybe its some memory issues, I would try to test the sketch without the display, and remove all display code inclusive removing the declarations #include <Adafruit_GFX.h> #include <Adafruit_SSD1306.h>
You have already successfully tested that code with display is working fine, now you need to test the Mysensors code without display code.

If this is successfully, I would combine the codes, but remove debug, remove all code for Serial.print, and remove #define MY_DEBUG
