// This is an example of how to use the analog pins (ADC) on the Flipper Zero.
|
||
|
|
// The example uses a reference voltage of 2048mV (2.048V), but you can also use 2500mV (2.5V).
|
||
|
|
// The example reads the values of the analog pins A7, A6, and A4 and prints them to the console.
|
||
|
|
// The example also checks if the value of A7 is twice the value of A6 and breaks the loop if it is.
|
||
|
|
// The example uses the analog pins A7, A6, and A4, but you can also use PC3, PC1, and PC0.
