ESP32-Radio with Spectrum analyzer

based on the excellent https://github.com/Edzelf/ESP32-Radio

based on the modified code by Mirko Dalmonte
https://github.com/Edzelf/ESP32-Radio/issues/86
the code on the issues/86 does not compile due to poor export, some characters are missing: * /

I contacted Mirko, got the correct code, mixed with the updted version of the original Edzelf/ESP32-Radio one.

I downloaded the patches and plugins for VS1053b
http://www.vlsi.fi/en/support/software/vs10xxplugins.html
http://www.vlsi.fi/en/support/software/vs10xxpatches.html
and adapted them to my code.

There is no need to the patches,
but the plugin that do the spectrum analysis is transferred from the Flash memory to the VS1053 at the beginning, when ESP32 starts. It is called within the code at regular samples.

I adapted the code to suit my 2.4" TFT ILI9341 module display.
I have no touch interface on this model.

Versions:
05/06/2020 added one line to avoid a possible division by zero and range if there is no internet
30/05/2020 Updated schematic + code: Encoder connection changed, TFT_LED also, added Encoder with a 100 nF capacitor between Enc_SW and GND
29/05/2020 Updated code with 14 FFT bars on all the witdh of the TFT screen
28/05/2020 First release

First begin by putting the correct ssid / pw

wifi_00 = ssid1/pw1
wifi_01 = ssid2/pw2

if you don't have an sd card connected, then comment the line

pin_sd_cs = 21

this is also valid for or the options that are different from yours (pin_ir = 35 ...)

You can connect to your

http://192.168.1.???/config.html

to put this config

On the sdcard you must put MP3 files with no spaces or fancy characters in the filenames. You can save the playlist as explained in https://github.com/Edzelf/ESP32-Radio/blob/master/doc/ESP32-radio.pdf
