"The commented line does not work..." <- > <@enaut:teilgedanken.de> The commented line does not work because `.delay` and `start` want to own `syst` (`ctx.core.SYST`). But I want to use a display which requires a `&mut Delay` > ```rust > let systick_mono_token = rtic_monotonics::create_systick_token!(); > //let mut delay = syst.delay(&clocks); > Systick::start(syst, SYSFREQ, systick_mono_token); > ``` > How do I get a delay for this function: https://docs.rs/st7735-lcd/0.10.0/st7735_lcd/struct.ST7735.html#method.init ? I found the answer: `let mut delay = ctx.device.TIM1.delay_us(&clocks);` I also found/rediscovered a trick: because it is sometimes hard to find which types implement a required trait, you can look in the implementors section. However, for the embedded crates this section is often empty - but if you already listed the necessary crates as dependencies then you can use `cargo doc --open` to build the docs for all dependencies... in these self built docs the implementors section is populated with all things needed.
