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.
To fix Ethernet library, just copy these following files into the Ethernet library directory to overwrite the old files:
You can also use the forked and modified library at Patched Ethernet
To fix EthernetLarge library, just copy these following files into the EthernetLarge library directory to overwrite the old files:
You can also use the forked and modified library at Patched EthernetLarge
To fix Ethernet2 library, just copy these following files into the Ethernet2 library directory to overwrite the old files:

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:
To fix ESP32 compile error, just copy the following file into the ESP32 cores/esp32 directory (e.g. ./arduino-1.8.19/hardware/espressif/cores/esp32) to overwrite the old file:
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-1.8.19/hardware/esp8266com/esp8266/libraries/Ethernet directory

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.
- ADC1 controls ADC function for pins GPIO32-GPIO39
- ADC2 controls ADC function for pins GPIO0, 2, 4, 12-15, 25-27
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).

Subscribed to /mqttPubSub => Hello from WiFiMQTToverWebSocketSecure on Nano RP2040 ConnectDebug is enabled by default on Serial. Debug Level from 0 to 4. To disable, change the MQTT_PUBSUB_LOGLEVEL to 0
#define MQTT_PUBSUB_DEBUG_PORT Serial
// Debug Level from 0 to 4
#define _MQTT_PUBSUB_LOGLEVEL_ 1If 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.
