Important Change from v3.7.0

Please have a look at HOWTO Fix Multiple Definitions Linker Error

From v3.7.2, you can use the new setUDP() function for auto-switching between WiFi and Ethernet UDP to update NTP time.

Check examples ESP_WiFi_ETH_NTPClient_Advanced and WT32_WiFi_ETH01_NTPClient_Advanced for a demo.

Why do we need this NTPClient_Generic library

Features

The NTPClient_Generic library is designed to work in conjunction with the Arduino Time library, which must also be installed on your system. This documentation assumes some familiarity with the Time library.

The primary goal of the NTPClient_Generic library is to enable the creation of an NTPClient to connect to NTP time-servers to get time and keep local time in sync. For ESP8266/ESP32, WT32_ETH01 (ESP32 + LAN8720), nRF52, SAMD21/SAMD51, STM32F/L/H/G/WB/MP1, Teensy, RP2040-based boards (Nano_RP2040_Connect, RASPBERRY_PI_PICO), etc. besides AVR, using ESP WiFi, WiFiNINA, Ethernet W5x00, ENC28J60, LAN8742A, ESP8266/ESP32 AT-command WiFi. But whether hardware RTC or another time-keeping source is present is not mandatory, since the Time library library can function as a software RTC without additional hardware (although its accuracy is dependent on the accuracy of the microcontroller's system clock.)

The examples will demonstrate how to get the UTC time from NTP server, then update the DS3231 RTC or local clock to make sure the time is perfectly correct.

In the examples, the interval to get perfect time from the NTP server to update RTC and/or local clock is configurable to ensure the RTC and/or local clock accuracy.

This NTPClient_Generic library is based on and modified from Fabrice Weinberg's NTPClient Library to add functions, features and as well as support to many boards and shields.

To use Serial1 on some STM32 boards without Serial1 definition (Nucleo-144 NUCLEO_F767ZI, Nucleo-64 NUCLEO_L053R8, etc.) boards, you have to copy the files STM32 variant.h into STM32 stm32 directory (~/.arduino15/packages/STM32/hardware/stm32/2.3.0). You have to modify the files corresponding to your boards, this is just an illustration how to do.

Supposing the STM32 stm32 core version is 2.3.0. These files must be copied into the directory:

~/.arduino15/packages/STM32/hardware/stm32/2.3.0/variants/STM32F7xx/F765Z(G-I)T_F767Z(G-I)T_F777ZIT/NUCLEO_F767ZI/variant.h for Nucleo-144 NUCLEO_F767ZI.
~/.arduino15/packages/STM32/hardware/stm32/2.3.0/variants/STM32L0xx/L052R(6-8)T_L053R(6-8)T_L063R8T/NUCLEO_L053R8/variant.h for Nucleo-64 NUCLEO_L053R8.

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz, these files must be copied into the corresponding directory:

~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/variants/STM32F7xx/F765Z(G-I)T_F767Z(G-I)T_F777ZIT/NUCLEO_F767ZI/variant.h
~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/variants/STM32L0xx/L052R(6-8)T_L053R(6-8)T_L063R8T/NUCLEO_L053R8/variant.h

8. For RP2040-based boards using Earle Philhower arduino-pico core

8.1 To use BOARD_NAME

To be able to automatically detect and display BOARD_NAME on RP2040-based boards (RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040, GENERIC_RP2040, etc) boards, you have to copy the file RP2040 platform.txt into rp2040 directory (~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0).

Supposing the rp2040 core version is 1.4.0. This file must be copied into the directory:

~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0/platform.txt

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz This file must be copied into the directory:

~/.arduino15/packages/rp2040/hardware/rp2040/x.yy.zz/platform.txt

With core after v1.5.0, this step is not necessary anymore thanks to the PR Add -DBOARD_NAME="{build.board}" #136.

8.2 To avoid compile error relating to microsecondsToClockCycles

Some libraries, such as Adafruit DHT-sensor-library, require the definition of microsecondsToClockCycles(). To be able to compile and run on RP2040-based boards, you have to copy the files in RP2040 Arduino.h into rp2040 directory (~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0).

Supposing the rp2040 core version is 1.4.0. This file must be copied to replace:

~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0/cores/rp2040/Arduino.h

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz This file must be copied to replace:

~/.arduino15/packages/rp2040/hardware/rp2040/x.yy.zz/cores/rp2040/Arduino.h

With core after v1.5.0, this step is not necessary anymore thanks to the PR Add defs for compatibility #142.

9. For Portenta_H7 boards using Arduino IDE in Linux

~/.arduino15/packages/realtek/hardware/AmebaD/x.yy.zz/cores/arduino/avr/pgmspace.h

11. For SAMD21 and SAMD51 boards using ArduinoCore-fab-sam core

To avoid compile error relating to SAMD21/SAMD51, you have to copy the file ArduinoCore-fab-sam core pgmspace.h into ArduinoCore-fab-sam samd directory (~/.arduino15/packages/Fab_SAM_Arduino/hardware/samd/1.7.0/boards.txt).

Supposing the ArduinoCore-fab-sam samd core version is 1.7.0. This file must be copied into the directory:

~/.arduino15/packages/Fab_SAM_Arduino/hardware/samd/1.7.0/boards.txt

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz This file must be copied into the directory:

~/.arduino15/packages/Fab_SAM_Arduino/hardware/samd/x.yy.zz/boards.txt

12. For Seeeduino RP2040 boards

To be able to compile, run and automatically detect and display BOARD_NAME on Seeeduino RP2040 (XIAO RP2040, Wio RP2040 Mini) boards, you have to copy the whole Seeeduino RP2040 Packages_Patches directory into Seeeduino samd directory (~/.arduino15/packages/Seeeduino/hardware/rp2040/2.7.2).

Supposing the Seeeduino SAMD core version is 2.7.2. This file must be copied into the directory:

Libraries' Patches

1. For application requiring 2K+ HTML page

If your application requires 2K+ HTML page, the current Ethernet library must be modified if you are using W5200/W5500 Ethernet shields. W5100 is not supported for 2K+ buffer. If you use boards requiring different CS/SS pin for W5x00 Ethernet shield, for example ESP32, ESP8266, nRF52, etc., you also have to modify the following libraries to be able to specify the CS/SS pin correctly.

2. For Ethernet library

To fix Ethernet library, just copy these following files into the Ethernet library directory to overwrite the old files:

3. For EthernetLarge library

To fix EthernetLarge library, just copy these following files into the EthernetLarge library directory to overwrite the old files:

4. For Ethernet2 library

To fix Ethernet2 library, just copy these following files into the Ethernet2 library directory to overwrite the old files:

To add UDP Multicast support, necessary for the UPnP_Generic library:

5. For Ethernet3 library

To fix Ethernet3 library, just copy these following files into the Ethernet3 library directory to overwrite the old files:
- Ethernet3.h
- Ethernet3.cpp

6. For UIPEthernet library

To be able to compile and run on nRF52 boards with ENC28J60 using UIPEthernet library, you have to copy these following files into the UIPEthernet utility directory to overwrite the old files:

7. For fixing ESP32 compile error

To fix ESP32 compile error, just copy the following file into the ESP32 cores/esp32 directory (e.g. ./arduino-1.8.13/hardware/espressif/cores/esp32) to overwrite the old file:

Server.h

8. For fixing ESP8266 compile error

To fix ESP8266 compile error such as

error: 'class EthernetClass' has no member named 'init'
Ethernet.init (USE_THIS_SS_PIN);

just rename the following file in ./arduino-1.8.13/hardware/esp8266com/esp8266/libraries/Ethernet directory

From Ethernet.h to Ethernet_ESP8266.h

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.

You can use

#include <NTPClient_Generic.hpp>               //https://github.com/khoih-prog/NTPClient_Generic

in many files. But be sure to use the following #include <NTPClient_Generic.h> in just 1 .h, .cpp or .ino file, which must not be included in any other file, to avoid Multiple Definitions Linker Error

// To be included only in main(), .ino with setup() to avoid `Multiple Definitions` Linker Error
#include <NTPClient_Generic.h>                //https://github.com/khoih-prog/NTPClient_Generic

Check multiFileProject for a demo how to avoid multiple-definitions linker error for multiple-file project

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 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

In ADC2, there're two locks used for different cases:

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.

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 to work with ESP32 WiFi/BlueTooth (BT/BLE).

Important Notes

Code is restructured to provide flexibility to make it easy to support many more WiFi/Ethernet modules/shields in the future. Please delete the .cpp files, replaced by .hpp files, in the src directory, if *.cpp files still exist after installing new version.
For Adafruit nRF52, use the SPI's pin as follows:
- SS/CS = 10
- SPI_MOSI = MO(SI)
- SPI_MISO = MI(SO)
- SPI_SCK = SCK
For Adafruit SAMD21/SAMD51, use the SPI's CS/SS pin as follows:
- Itsy-Bitsy M0/M4, Feather M0 (Express), Hallowing M0 Express, Zero, Metro M0 => use CS = 16 = pin A2
- Feather M4 (SAMD51) => use SS/CS = 9
- Grand Central M4 => use SS/CS = 53
- Hallowing M4 => use SS/CS = 10
- Metro M4 AirLift => use SS/CS = 36

To know the default CS/SS pins of not listed boards, check the related variant.h files in

~/.arduino15/packages/adafruit/hardware/samd/x.y.zz/variants/board_name/variant.h

For Arduino SAM DUE, use the SPI's pin as follows:
- SS/CS = 10
- SPI_MOSI = 75 ( pin 4 @ ICSP connector )
- SPI_MISO = 74 ( pin 1 @ ICSP connector )
- SPI_SCK = 76 ( pin 3 @ ICSP connector )

Debug

Debug is enabled by default on Serial. To disable, add at the beginning of sketch

/* Comment this out to disable prints and save space */
#define NTP_DBG_PORT                Serial

// Debug Level from 0 to 4
#define _NTP_LOGLEVEL_              0

Troubleshooting

If you get compilation errors, more often than not, you may need to install a newer version of the board's core, dependent libraries or this library version.

Sometimes, the library will only work if you update the core to the newer or older version because some function compatibility.
