ESP32 WEBRADIO with analogcontrol

Attention, if the radio should not be configured via the web interface.Please first enter the SSID and passwords into the sourcecode , then programm the ESP32. He creates a pwd.txt and saves it there. From now are, you can only change them via the web interface/FTP , or you have to format the FFS via IDE.

Or change the code for temp :

void setup() { SPIFFS.remove("/pwd.txt"); // remover here after reboot

the pwd will be erased and after reboot change ist back to

void setup() { // SPIFFS.remove("/pwd.txt"); // alte datei löschen , remover here after reboot

The problem with many web radios is that they operate like small computers. The goal here is to build a web radio that can be used like a normal radio, but can also be used with a web interface at the same time.

To make this possible, a potentiometer was chosen. You can connect this to a dial drive in a radio, or overlook it with a button.
Each station is therefore assigned to a certain position of the potentiometer.

In order to ensure a proper coordination, there is an electronic lock addet.

The station data can be predefined in the source code or (later) changed via FTP or a WEB interface.

Properties
- Analog tuning
- Up to 3 AP access data
- Web interface for control and administration
- WIFI scanner
- Playback buffer
- Autoreconnect, in case of buffer underflow
- FTP access

Initial installation
If no WIFI data are available, an access point is set up.
data :
SSID: WEB RADIO IP: 192.168.4.22
IP: 192.168.4.22

It may be that the device starts again (must see where the error is), so (if necessary), wait until the radio has resstarted.

Flash codes:
Slow: Try a WIFI connection (3 different).

Slow flashing: device creates, an access point and waiting for connection.

Fast flashing: Once connected, the device can be accessed via FTP or browser.

Attention, if you change the data on the web interface,
you have to press the send button,
which is available next to the fields.

For the station list, the save button for the station list must then be pressed.
As soon as a new url is entered, the radio tries to reach it so you can see if everything is OK.

For the WIFI data´s, you nedd only press send button, the data will be saved immediately.

If you like, please help me to make it better. Any suggestions ?
