+### Note for Platform IO using ESP32 LittleFS
+
+In Platform IO, to fix the error when using [`LittleFS_esp32 v1.0`](https://github.com/lorol/LITTLEFS) for ESP32-based boards with ESP32 core v1.0.4- (ESP-IDF v3.2-), uncomment the following line
+
+from
+
+```
+//#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */
+```
+
+to
+
+```
+#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */
+```
+
+It's advisable to use the latest [`LittleFS_esp32 v1.0.5+`](https://github.com/lorol/LITTLEFS) to avoid the issue.
+
+Thanks to [Roshan](https://github.com/solroshan) to report the issue in [Error esp_littlefs.c 'utime_p'](https://github.com/khoih-prog/ESPAsync_WiFiManager/issues/28)

+
+### HOWTO Fix `Multiple Definitions` Linker Error
+
+The current library implementation, using xyz-Impl.h instead of standard xyz.cpp, possibly creates certain `Multiple Definitions` Linker error in certain use cases. Although it's simple to just modify several lines of code, either in the library or in the application, the library is adding a separate source directory, named src_cpp, besides the standard src directory.
+
+To use the old standard cpp way, just 
+
+1. **Rename the h-only src directory into src_h.**
+2. **Then rename the cpp src_cpp directory into src.**
+3. Close then reopen the application code in Arduino IDE, etc. to recompile from scratch.

+
+### HOWTO Use analogRead() with ESP32 running WiFi and/or BlueTooth (BT/BLE)
+
+Please have a look at [**ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example**](https://github.com/khoih-prog/ESP_WiFiManager/issues/39) to have more detailed description and solution of the issue.
+
+#### 1.  ESP32 has 2 ADCs, named ADC1 and ADC2
+
+#### 2. ESP32 ADCs functions
+
+- ADC1 controls ADC function for pins **GPIO32-GPIO39**
+- ADC2 controls ADC function for pins **GPIO0, 2, 4, 12-15, 25-27**
+
+#### 3.. ESP32 WiFi uses ADC2 for WiFi functions
+
+Look in file [**adc_common.c**](https://github.com/espressif/esp-idf/blob/master/components/driver/adc_common.c#L61)
+
+> In ADC2, there're two locks used for different cases:
+> 1. lock shared with app and Wi-Fi:
+>    ESP32:
+>         When Wi-Fi using the ADC2, we assume it will never stop, so app checks the lock and returns immediately if failed.
+>    ESP32S2:
+>         The controller's control over the ADC is determined by the arbiter. There is no need to control by lock.
+> 
+> 2. lock shared between tasks:
+>    when several tasks sharing the ADC2, we want to guarantee
+>    all the requests will be handled.
+>    Since conversions are short (about 31us), app returns the lock very soon,
+>    we use a spinlock to stand there waiting to do conversions one by one.
+> 
+> adc2_spinlock should be acquired first, then adc2_wifi_lock or rtc_spinlock.
+
+
+- In order to use ADC2 for other functions, we have to **acquire complicated firmware locks and very difficult to do**
+- So, it's not advisable to use ADC2 with WiFi/BlueTooth (BT/BLE).
+- Use ADC1, and pins GPIO32-GPIO39
+- If somehow it's a must to use those pins serviced by ADC2 (**GPIO0, 2, 4, 12, 13, 14, 15, 25, 26 and 27**), use the **fix mentioned at the end** of [**ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example**](https://github.com/khoih-prog/ESP_WiFiManager/issues/39) to work with ESP32 WiFi/BlueTooth (BT/BLE).
