Hi and sorry for the delay...i only just saw this comment. I found a sevensegment.ttf true type font online (eg Krafti Lab or other) which i then downloaded and installed into Windows. In the Nextion Editor, use the Font generator tool from inside the Tools menu. You may have to experiment with font height setting but I used 16 pixel. If you require different font styles or different sizes in your nextion project you will need to repeat the font creation process for each required Font & size. Name the created nextion Fonts as say SevenSeg16 , Arial 22 etc Cheers Steve

Really cool project, Im using this command to send the 3 (0xFF) // ------ Nextion Document ------// const byte ndt[3] = {255,255,255}; Serial.write(ndt,3);

Great content! I'd like to suggest a comparison between Nextion displays with Proculus LCD Modules. I think it would be a interesting fight :) https://www.proculustech.com/

Those displays look interesting, a bit more expensive and perhaps not so widespread use at the moment.
