AsyncWebClientRepeating_STM32.ino - Dead simple AsyncHTTPRequest for ESP8266, ESP32 and currently STM32 with built-in LAN8742A Ethernet
|
|
|
|
For ESP8266, ESP32 and STM32 with built-in LAN8742A Ethernet (Nucleo-144, DISCOVERY, etc)
|
|
|
|
AsyncHTTPRequest_Generic is a library for the ESP8266, ESP32 and currently STM32 run built-in Ethernet WebServer
|
|
|
|
Based on and modified from asyncHTTPrequest Library (https://github.com/boblemaire/asyncHTTPrequest)
