* Remove Peripheral/PeripheralRef * Make ADC unit and channel structs more readable by avoiding const generics * Remove unused parameter * fix forgotten reference to the old ADCU syntax * Mention that we have removed the prelude module * try_into methods for changing the pin type

//! Turn an LED on/off depending on the state of a button
|
|
//!
|
|
//! This assumes that a LED is connected to GPIO4.
|
|
//! Additionally this assumes a button connected to GPIO9.
|
|
//! On an ESP32C3 development board this is the BOOT button.
|
|
//!
|
|
//! Depending on your target and the board you are using you should change the pins.
|
|
//! If your board doesn't have on-board LEDs don't forget to add an appropriate resistor.
