Hi ,

First off all , thank you for this awesome library :)

Now im blocked on an implementation of the currentPageIdCallback I have no idea how to implement that... Should i give a pointer of function ?

Can you give me an exemple of implementation ?

Many thanks for you help

hi,

first initialize the nextion instance: SoftwareSerial nexSerial(D2, D1); // RX, TX Nextion *nextion = Nextion::GetInstance(nexSerial);

-CurrentPageId is callback function that you need initialize: // functional callbacks nextion->currentPageIdCallback = currentPageCallback;

And callback function definition e.g... void currentPageCallback(uint8_t pageId) { if(currentPageId==pageId) { return; } currentPageId=pageId; }
