Dashboard with ESP32 and Nextion 7" and CAN bus

Switchable CAN bus, i'm trying the rpm with arduino(mcp2515)
If i'm switching on or off the CAN bus, then i'm resarting the esp32.
Temperature measurement: if the sensors unconnected, the display shows - 99. 9 degree celsius
Temperature calibration with Steinhart Hart equal. Three resistance values and three temperature values, and i can calculation the steinhart coefficients with excel calculator

Hello Tamas!
Nice work in general with all this displays and stuff. Keep it up!
I'm kinda curious on how did you managed to change the gauge needle? I can't find a way to make it look different in my nextion editor. Did you used pictures for it? Thanks

Clearly you have an Arduino Mega2560 connected to your Nextion Display. Not the ESP32.

Link to the files for us that have the hardware. I'd like to make an English version?

How to send data from esp32 to nextion display???

[@Thomas10100]

via uart2, serial communication

[@idramirezs]

que buen video, seria maravilloso el nos enseñara como hacerlo o el codigo para poder analizarlo
y poder aprender

Lot of development is in this project, sorry, that i can't share my code. I have begun this project since more than one year.

Sharing isn't cost you any money, instead you’ll won hearts of lots. So keep sharing!
