  HI , thanks for your reply.
  i have tried the code in your link and the results are bellow

  i have removed all the other Arduino libraries from the libraries folder, leaving only the ones copied from your archive
  on first compilation i got the bellow

  i presumed that the fies should reference the ui_img_elecrow_logo_png, ui_img_humidity_png, ui_img_off_png, ui_img_temp_png
  which were included in the folder. i have modified the ui.c and ui.h to match the files and the program compiled , but with the same results. its shots down when the first temp/hum Mqtt message is sent .

  if Mqtt is not connected, it is no problem, it does not shut down.

  i hvae seen on the forum :I changed the frame rate from 16mhz to 8 and mqtt worked - but the display flickered
  I found that 12 mhz worked and 14 mhz does not work,
  When I first boot up the display it flickers a little then seems to stop or at least is not noticiable.
  Even at 16mhz there is some flicker on start up then it "goes away".
  where do i change the frame rate?

  Hello Adrian,
  You can change the frame rate at line 84 in 7.0-inch_Squareline_Demo.ino

  Hi, i thought it was somewhere else. i have tried changing the freq but the same
  but i believe i found where the program crashes.
  in async-mqtt-client/src
  /AsyncMqttClient.cpp
  if (_state != CONNECTED || GET_FREE_MEMORY() < MQTT_MIN_FREE_MEMORY) return 0;
  i have commented the line out and the program is working fine, Mqtt tested and working. i dont think this is the way to go, this memory check it is important somewhere but i do not have the knowledge to dig any deeper. can you have a look to see what to do next?

  best regards
