ESP8266

Hi have problem in ESP8266, open return false:
Serial.println(ini_open ("/setup.ini"));
ClientSSID = ini_read ("network", "ClientSSID","prova");
Serial.println(ClientSSID);
ClientPassword = ini_read ("network", "ClientPassword"," ");
Serial.println(ClientPassword);
HostSSID = ini_read ("network", "HostSSID","CV19Archimede");
HostPassword = ini_read ("network", "HostPassword","cv19");
HostIp = ini_read ("network", "HostIp","192.168.1.1");
ini_close();

ini file:
[network]
ClientSSID = sadad
ClientPassword = 25399
HostSSID = dfsdd
HostPassword = 123
HostIp = 192.168.1.1

Hi !
Just did some tests yesterday. Works very well on ESP8266 and ESP32.
This was my testcode for both chips:

#include <Arduino.h>
//#include "LittleFS.h"
#include "LITTLEFS.h"
#define LittleFS LITTLEFS
#include "SPIFFS_ini.h"

void setup() {
    Serial.begin(115200);

    if (!LittleFS.begin()) {
        Serial.println("An Error has occurred while mounting LittleFS");
        return;
    }

    //LittleFS.format();

    File file = LittleFS.open("/setup.ini", "r");
    if (!file) {
        Serial.println("Failed to open file for reading");
        return;
    }

    Serial.println("File Content:");
    while (file.available()) {
        Serial.write(file.read());
    }
    file.close();

    Serial.println(ini_open("/setup.ini"));
    Serial.println(ini_write("Test", "Key", String(123.33)));
    Serial.println(ini_write("Device_3", "Pin_Mode", "NIX"));
    Serial.println(ini_close());

    for (size_t i = 0; i < 10; i++)
    {


        Serial.println(ESP.getFreeHeap());

        Serial.println(ini_open("/setup.ini"));
        Serial.println(ESP.getFreeHeap());
        String ClientSSID = ini_read("Wifi", "SSID", "N/A");
        Serial.println(ClientSSID);
        Serial.println(ESP.getFreeHeap());
        String ClientPassword = ini_read("Device_1", "Description", " ");
        Serial.println(ClientPassword);
        ini_close();
        Serial.println(ESP.getFreeHeap());

        delay(400);
    }
}

void loop() {

}

The only problem where the slightly different LittleFS Libs ...

And I made a small fix in the cpp file (Typecast p_ini_file). Otherwise it won´t compile for ESP32:

bool ini_close() {
  if (ini) ini.close();
  ini = LittleFS.open(ini_fname, "w");
  ini.write((const uint8_t*)p_ini_file, size_ini_file);

Maybe your filesystem is not formatted correctly with LittleFS ?
