//! This shows a very basic example of running code on the LP core.
|
|
//!
|
|
//! Code on LP core increments a counter and continuously toggles LED. The
|
|
//! current value is printed by the HP core.
|
|
//!
|
|
//! Make sure to first compile the `esp-lp-hal/examples/blinky.rs` example
|
|
//!
|
|
//! The following wiring is assumed:
|
|
//! - LED => GPIO1
|
|
|
|
//% CHIPS: esp32c6
|
|
//% FEATURES: esp-hal/unstable
