changing the code to automatically inlcude the correct Little-filesystem library ESP8266 <LittleFS.h> / ESP32)<LITTLEFS.h> #12
Description
Hi I made a small change to the code so that the correct littl-flsesystem-library is included on compiling
here is my modified version
I have tested it with an ESP32 and an ESP8266-board and it does compile and run as expected
the modification is here
#ifdef ESP8266
#include <LittleFS.h>
#define FILESYSTEM LittleFS
ESP8266WebServer server(80);
#elif defined(ESP32)
#include <LITTLEFS.h>
#define FILESYSTEM LITTLEFS
WebServer server(80);
#endif
full code is this
#include <esp-fs-webserver.h> // https://github.com/cotestatnt/esp-fs-webserver
#include <FS.h>
#ifndef LED_BUILTIN
#define LED_BUILTIN 2
#endif
// Test "options" values
bool boolVar = true;
uint32_t longVar = 1234567890;
String stringVar = "Test option String";
uint8_t ledPin = LED_BUILTIN;
int myTestVar1;
int myTestVar2;
int myTestVar3;
// Timezone definition to get properly time from NTP server
#define MYTZ "CET-1CEST,M3.5.0,M10.5.0/3"
struct tm Time;
#ifdef ESP8266
#include <LittleFS.h>
#define FILESYSTEM LittleFS
ESP8266WebServer server(80);
#elif defined(ESP32)
#include <LITTLEFS.h>
#define FILESYSTEM LITTLEFS
WebServer server(80);
#endif
