Can't get ESP8266 to be AP Mode.. #82

Hi MD, im clueless how to change your library example of Parola Scrolling ESP8266 to make it WifiAP Mode.

this is my code.

`// Use the Parola library to scroll text on the display // // Demonstrates receiving and displaying text received from a web interface. // // User can enter text through a web browser and this will display as a // scrolling message on the display. Some parameters for the text can also // be controlled from the web page. // // IP address for the ESP8266 is displayed on the scrolling display // after startup initialization and connection to the WiFi network. // // Connections for ESP8266 hardware SPI are: // Vcc 3v3 LED matrices seem to work at 3.3V // GND GND GND // DIN D7 HSPID or HMOSI // CS or LD D8 HSPICS or HCS // CLK D5 CLK or HCLK // // MD_MAX72XX library can be found at https://github.com/MajicDesigns/MD_MAX72XX //

Sorry, I can't help you yet. I'm still learning too

MajicDesigns commented 3 years ago

This does not seem to be a bug in the library, rather a request for specific help. Your best bet is to go to the Arduino forum (Arduino.cc) and ask for help there, either in the programming section (https://forum.arduino.cc/c/using-arduino/programming-questions/20) or the Parola support thread (https://forum.arduino.cc/t/led-matrix-display-md_parola-md_max72xx-and-md_maxpanel/167082/1714) where others with experience in what you are doing may be able to help.

thanks for the suggestion, i will try later
