RF Powermeter - Uploading HMI file

The Nextion display needs the content defined in the file PowerMeter.HMI. You can either upload it with the Nextion editor via a serial link to the display or you can copy the TFT file to an SD card and put this into the socket on the Nextion display.

I assume the simplest way is to copy the TFT file on an SD card.

  • The TFT file can be found if you open the HMI file in the Nexion editor and then select "File - Open build folder" from the menu bar.
  • In the latest Nextion-Editor the tft-file must be exported via an exta entry in the "File" menu. It is no longer created during compilation.
