12-bit ADC

ESP32 has a 12-bit adc (afaik) and returns values between 0 and 4095. Is this supported in e.g. mux.read?

Using boards faster than 30MHz

Hello,
I'm currently working with a Teensy 4.0 and a 4051 to read height pushbuttons, and I came across a bug using this library :

When pressing a button, multiple channels read as pressed, however the bug disappears when the sketch is loaded with the 24MHz clock speed.
It seems like the board is too fast for the Mux, which doesn't have the time to switch between inputs. The bug disappeared when adding a 1 millisecond delay in Mux.cpp, in the setChannel function, which seems to confirm this.

I would like to share my sketch without other people having to modify the library, are there any ways to do that ?
Let me know your thoughts on this !

(I'm French so please excuse me for any weird phrasing or mistakes...)

[ESP32] error: 'analogWrite' was not declared in this scope

When trying to compile this library for ESP32 using PlatformIO the following error occurs:

.pio/libdeps/lolin32/Analog-Digital Multiplexers_ID5363/src/Mux.cpp: In member function 'int8_t Mux::write(uint8_t, int8_t)':
.pio/libdeps/lolin32/Analog-Digital Multiplexers_ID5363/src/Mux.cpp:121:32: error: 'analogWrite' was not declared in this scope
     analogWrite(signalPin, data);
                                ^

platformio config:

[env:lolin32]
platform = espressif32
board = lolin32
framework = arduino

lib_deps =
  Analog-Digital Multiplexers

"Pin" conflicts with FastLED library

If using this library and the FastLED library in a sketch, an error is thrown saying "Pin" is ambiguous in the initialisation declaration ("Pin" is also used by FastLED apparently). I got around it by changing "Pin" to "sigPin" in the library source files, but maybe I'm missing something and it can be done without changing anything in the source files?

mux.read(..) apparently doesn't work in setup()

Hello, in order to simplify my code (to later use the Bounce2 library) I try to create an array of this type before void setup:

int buttonPin [] = {mux.read (0), mux.read (1), mux.read (2), mux.read (3), ... }

However, renaming mux.read (i) only works if it is done inside the void loop.

Am I right or am I doing something wrong?
