khoih-prog / EthernetWebServer

This is simple yet complete WebServer library for AVR, AVR Dx, Portenta_H7, Teensy, SAM DUE, SAMD21/SAMD51, nRF52, STM32, RP2040-based, etc. boards running Ethernet shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32. Coexisting now with `ESP32 WebServer` and `ESP8266 ESP8266WebServer` libraries. Ethernet_Generic library is used as default for W5x00 with custom SPI

ESP32 keeps rebooting when trying to use pointers. #52

Closed Vitor1827 closed 2 years ago

Hello,

It's possible to use pointers when creating the EthernetWebServer class object, to change port number on setup?

I can compile the code using sometihng like this...

EthernetWebServer *server

void setup() {
  server = new EthernetWebServer(desiredPortNumber);
  server->begin();

But when I turn on the board, it keeps rebooting non stop.

Rebooting...

That's what happens when I turn on the board...

Can you give me some advice about what to do to solve this, or, any other way to change port number on another part of the code?

You must have done something wrong in your code.

Try the new AdvancedWebServer_Ptr example and learn how to use pointer.
