[sdiy] Need some advice for Raspberry PICO + Micropython

[francesco mulassano]

hi!
I need some advice for a project that i've started to learn RP2040 and
Micropython

HARDWARE
RP PICO
3 position switch
1 button
some leds
___

to save Pins, the switch is connected to a single ADC input and through a
comparator, i have 3 different voltage values that i use to identify the
switch position.

I use the switch to activate 3 different modes
MODE 0, MODE 1 and MODE 2

MODE 0
is a program selection function
when in this modality, the button serve to select the 'APP', indicated by a
led in a 3x3 matrix
selected app is lit.

MODE 1
in this mode, the selected app RUNS!

MODE 2
reserve

___

What can I do
- I do the detect of the MODE
- when I am in MODE 0, I call the appSelect function and with the button, i
cycle on the LEDs

*the problem*
-
*when I go back to MODE 1, it should leave the select mode and run the
selected APP but unfortunately the appSelect remains active*

The CODE

*main.py*
