> <@adamgreig:matrix.org> do you have some code where you have the static_cell mutex and can't get the peripheral back after the task used it?

 * I'm probably missing some stuff but just whipped this up in gedit.
context: using embassy executor in thread mode. I didn't include the crates, the mutexes are from embassy\_sync.

```
type PDOut = Mutex<CriticalSectionRawMutex, PinDriver<'static, AnyIOPin, Output>>;
static LED_1 StaticCell<PDOut> = StaticCell::new();

#[main]
async fn main() {
	let led_1 = LED_1.init(Mutex::new(                                                                                     
		PinDriver::output(p.pins.gpio10.downgrade()).unwrap(),                                                                        
	));
   	spawner.spawn(mytask(led_1)).ok; //am I passing led_1 correctly? This does send it to my_task.
   	something_that_blocks_until_mytask_exits.await;
   	led_1.toggle(); //is this right? 
}
   
#[task]
async fn mytask(led: &'static PDOut) {
	Timer::after_secs(1).await;
 	led.toggle();
}
```
