Why do we need this MySQL_MariaDB_Generic library

Features

Have you ever wanted to connect your Arduino project to a database to either store the data you've collected or retrieve data saved to trigger events in your sketch?

Well, now you can connect your Arduino project directly to a MySQL / MariaDB server without using an intermediate computer or a web-based or cloud-based service. Having direct access to a MySQL / MariaDB database server means you can store data acquired from your project as well as check values stored in tables on the server.

This also means you can setup your own, local MySQL server to store your data further removing the need for Internet connectivity. If that is not an issue, you can still connect to and store data on a MySQL server via your network, Internet, or even in the cloud!

This MySQL_MariaDB_Generic library will let you to do exactly that and more!

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 include this .hpp file

// Can be included as many times as necessary, without `Multiple Definitions` Linker Error
#include "MySQL_Generic.hpp"     //https://github.com/khoih-prog/MySQL_Generic

in many files. But be sure to use the following .h file 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 "MySQL_Generic.h"           //https://github.com/khoih-prog/MySQL_Generic

Check the new multiFileProject_Ethernet example for a HOWTO demo.

Have a look at the discussion in Different behaviour using the src_cpp or src_h lib #80

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

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-1.8.12/hardware/espressif/cores/esp32) to overwrite the old file:

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 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:

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


Important Notes

  1. From v1.0.0, 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.

  2. For Adafruit nRF52, use the SPI's pins as follows:

  • SS/CS = 10
  • SPI_MOSI = MO(SI)
  • SPI_MISO = MI(SO)
  • SPI_SCK = SCK
  1. 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

  1. For Arduino SAM DUE, use the SPI's pins as follows:

  1. For RP2040, use the SPI's pins as follows:
  • SS/CS = GP17 default or GP5 by modifying defines.h
  • MOSI = GP19
  • MISO = GP16
  • SCK = GP18



Basic Usage

Please see Dr. Charles Bell's wiki documentation, especially Examples section for the best and detailed explanation.

There are many modifications to facilitate the usage of MySQL_MariaDB_Generic Library. Please have a look at the examples to see the differences.


1. To use Ethernet module/shield

Just select an Ethernet module/shield and the corresponding library to use in defines.h:

// Only one of the following to be true.
#define USE_ETHERNET_GENERIC      true
#define USE_ETHERNET_ESP8266      false
#define USE_ETHERNET_ENC          false
#define USE_ETHERNET_LAN8742A     false
#define USE_ETHERNET_LAN8720      false
#define USE_CUSTOM_ETHERNET       false
#define USE_UIP_ETHERNET          false

In the sketch:

#include "defines.h"

#include <MySQL_Generic_Ethernet.h>

...

MySQL_Connection conn((Client *)&client);
MySQL_Query sql_query = MySQL_Query(&conn);

2. To use WiFi module/shield

For ESP8266 or ESP32, don't need to select any WiFi module/shield in defines.h.

For remaining boards, just select a WiFi module/shield and the corresponding library to use in defines.h:

// Select only one of these libraries, only for boards other than ESP8266/ESP32
#define USING_WIFI_ESP_AT               false         // Using ESP8266_AT_WebServer lib (https://github.com/khoih-prog/ESP8266_AT_WebServer)
#define USING_WIFININA_GENERIC          false         // Using WiFiNINA_Generic library (https://github.com/khoih-prog/WiFiNINA_Generic)
#define USING_WIFININA                  false         // Using WiFiNINA library
#define USING_WIFIESPAT_LIB             true          // Using WiFiEspAT library (https://github.com/jandrassy/WiFiEspAT)
#define USING_WIFI_CUSTOM               false

In the sketch:

#include "defines.h"
#include "Credentials.h"

#include <MySQL_Generic_WiFi.h>

...

MySQL_Connection conn((Client *)&client);
MySQL_Query sql_query = MySQL_Query(&conn);

3. To use WiFiNINA module/shield

Can't use WiFiNINA for ESP8266 or ESP32.

For remaining boards, just select a library to use in defines.h:

// Select only one of these libraries, only for boards other than ESP8266/ESP32
#define USING_WIFININA_GENERIC        true
#define USING_WIFININA                false

In the sketch:

#include "defines.h"
#include "Credentials.h"

#include <MySQL_Generic_WiFiNINA.h>

...

MySQL_Connection conn((Client *)&client);
MySQL_Query sql_query = MySQL_Query(&conn);

Debug

Debug is enabled by default on Serial. Debug Level from 0 to 4. To disable, change the MYSQL_LOGLEVEL to 0

#define MYSQL_DEBUG_PORT      Serial

// Debug Level from 0 to 4
#define _MYSQL_LOGLEVEL_      1

Troubleshooting

If you get compilation errors, more often than not, you may need to install a newer version of the core for Arduino boards.

Sometimes, the library will only work if you update the board core to the latest version because I am using newly added functions.



Issues

Submit issues to: MySQL_MariaDB_Generic issues



TO DO

  1. Support more boards
  2. Support more non-compatible Ethernet Libraries such as Ethernet_Shield_W5200, EtherCard, EtherSia
  3. Bug fixing.
