I'm having trouble creating an EZ-B from an esp32. I know I've successfully done it in the past about a year ago - but now when I try I'm getting these error messages: C:\Users\dream\Downloads\EZ-ESP32 (1)\EZ-ESP32\ESP32PWM.cpp: In destructor 'virtual ESP32PWM::~ESP32PWM()': C:\Users\dream\Downloads\EZ-ESP32 (1)\EZ-ESP32\ESP32PWM.cpp:50:17: error: 'ledcDetachPin' was not declared in this scope; did you mean 'ledcDetach'?

It looks like you're encountering several issues related to the ESP32 firmware and the Arduino IDE. These errors are likely due to changes in the ESP32 libraries or the Arduino core since you last successfully compiled the firmware. Let's address these issues step by step.

1. Update ESP32 Libraries and Core

First, ensure that you have the latest ESP32 libraries and core installed in your Arduino IDE. You can do this by following these steps:

Open the Arduino IDE.
Go to File > Preferences.
In the "Additional Boards Manager URLs" field, add the following URL if it's not already there:
```
https://dl.espressif.com/dl/package_esp32_index.json
```
Go to Tools > Board > Boards Manager.
Search for "ESP32" and install the latest version.

2. Update the Firmware Code

The errors you're encountering suggest that some functions and constants have been renamed or deprecated. Here are the specific changes you need to make:

ESP32PWM.cpp

Replace all instances of ledcDetachPin with ledcDetach and ledcAttachPin with ledcAttach.

WiFiEvent Function

Replace all instances of SYSTEM_EVENT_* with their corresponding WIFI_EVENT_* or IP_EVENT_* constants. Here is a mapping for the changes:

SYSTEM_EVENT_WIFI_READY -> WIFI_EVENT_WIFI_READY
SYSTEM_EVENT_SCAN_DONE -> SC_EVENT_SCAN_DONE
SYSTEM_EVENT_STA_START -> WIFI_EVENT_STA_START
SYSTEM_EVENT_STA_STOP -> WIFI_EVENT_STA_STOP
SYSTEM_EVENT_STA_CONNECTED -> WIFI_EVENT_STA_CONNECTED
SYSTEM_EVENT_STA_DISCONNECTED -> WIFI_EVENT_STA_DISCONNECTED
SYSTEM_EVENT_STA_AUTHMODE_CHANGE -> WIFI_EVENT_STA_AUTHMODE_CHANGE
SYSTEM_EVENT_STA_GOT_IP -> IP_EVENT_STA_GOT_IP
SYSTEM_EVENT_STA_LOST_IP -> IP_EVENT_STA_LOST_IP
SYSTEM_EVENT_STA_WPS_ER_SUCCESS -> WIFI_EVENT_STA_WPS_ER_SUCCESS
SYSTEM_EVENT_STA_WPS_ER_FAILED -> WIFI_EVENT_STA_WPS_ER_FAILED
SYSTEM_EVENT_STA_WPS_ER_TIMEOUT -> WIFI_EVENT_STA_WPS_ER_TIMEOUT
SYSTEM_EVENT_STA_WPS_ER_PIN -> WIFI_EVENT_STA_WPS_ER_PIN
SYSTEM_EVENT_AP_START -> WIFI_EVENT_AP_START
SYSTEM_EVENT_AP_STOP -> WIFI_EVENT_AP_STOP
SYSTEM_EVENT_AP_STACONNECTED -> WIFI_EVENT_AP_STACONNECTED
SYSTEM_EVENT_AP_STADISCONNECTED -> WIFI_EVENT_AP_STADISCONNECTED
SYSTEM_EVENT_AP_STAIPASSIGNED -> IP_EVENT_AP_STAIPASSIGNED
SYSTEM_EVENT_AP_PROBEREQRECVED -> WIFI_EVENT_AP_PROBEREQRECVED
SYSTEM_EVENT_GOT_IP6 -> IP_EVENT_GOT_IP6
SYSTEM_EVENT_ETH_START -> ARDUINO_EVENT_ETH_START
SYSTEM_EVENT_ETH_STOP -> ARDUINO_EVENT_ETH_STOP
SYSTEM_EVENT_ETH_CONNECTED -> ARDUINO_EVENT_ETH_CONNECTED
SYSTEM_EVENT_ETH_DISCONNECTED -> ARDUINO_EVENT_ETH_DISCONNECTED
SYSTEM_EVENT_ETH_GOT_IP -> IP_EVENT_ETH_GOT_IP

analogWrite Function

The error call of overloaded 'analogWrite(byte, long int)' is ambiguous suggests that there are multiple definitions of analogWrite. Ensure that you are using the correct definition. You might need to cast the value to the appropriate type.

Replace:

analogWrite(translateaDigitalPort(port), map(pos, 0, 100, 0, 255));

With:

analogWrite(translateaDigitalPort(port), (int)map(pos, 0, 100, 0, 255));

3. Recompile the Firmware

After making these changes, try recompiling the firmware. If you encounter any further issues, please provide the updated error messages, and we can continue troubleshooting from there.

Summary of Changes

Update ESP32 libraries and core in Arduino IDE.
Replace ledcDetachPin with ledcDetach and ledcAttachPin with ledcAttach.
Replace SYSTEM_EVENT_* constants with their corresponding WIFI_EVENT_* or IP_EVENT_* constants.
Cast the value in the analogWrite function to int.

By following these steps, you should be able to resolve the compilation errors and successfully create an EZ-B from your ESP32. If you need further assistance, feel free to ask!
