I have no idea of which HTTPClient you are referring to but my suggestion is to

  1. Make sure that DM_BOARD_ETHERNET is enabled in dm_board_config.h
  2. Make sure that your HTTPClient is working without emWin
  3. Make sure that your emWin button is working without HTTPClient
  4. When all is working separately then try to combine it

Accepted Answer

The step 1 to 3 I've tried already, and all worked. But when I tried to combine them, it cloud'nt work. I don't know why.

I thought I found the problem. Now I want to ask the other question, how to change the MAC address by myself ?
