Hallo ich brauche für mein Projekt 4 GPIO-Pins und will RX und TX als GPIO verwenden. Leider komme ich nicht mehr weiter.
#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
#include <ESP8266mDNS.h>
// wireless network credentials:
const char* ssid = "xxxxx";
const char* password = "xxxxx";
// hostname for this system:
const char* host = "webcontrol";
// define GPIO pins:
const int output1 = 0; //GPIO0
const int output2 = 2; //GPIO2
const int output3 = 1; //TX GPIO1
const int output4 = 3; //RX GPIO3
// output status variables:
boolean output1_state = false;
boolean output2_state = false;
boolean output3_state = false;
boolean output4_state = false;
// web server on port 80:
ESP8266WebServer server(80);
String getContent()
{
// create content for the website:
String content = "<html><head><title>ESP8266 WebControl</title></head><body>";
content += "Home Control!
";
if (output1_state)

Serial.print('\n');
