Error Description
I'm trying to create a MonoTimer and the code is not compiling.
I'm receiving a message that could point to mixed crates or incompatibility in the dependencies.
Perhaps cortex-m v0.6.2 and cortex-m v0.5.10? I don't understand how is that cargo tree is listing cortex-m v0.6.2 as a dependency of cortex-m v0.5.10 (inside stm32f30x-hal v0.2.0dependency; see cargo tree output below).
Portion of code where I'm creating the MonoTimer:
let bp = stm32f30x::Peripherals::take().unwrap();
let cp = cortex_m::Peripherals::take().unwrap();
let mut rcc = bp.RCC.constrain();
let mut flash = bp.FLASH.constrain();
let clocks = rcc.cfgr.freeze(&mut flash.acr);
let timer = Delay::new(cp.SYST, clocks);
let chrono = MonoTimer::new(cp.DWT, clocks);Error message:
error[E0308]: mismatched types
--> src/core/mod.rs:27:37
|
27 | let chrono = MonoTimer::new(cp.DWT, clocks);
| ^^^^^^ expected struct `cortex_m::peripheral::DWT`, found a different struct `cortex_m::peripheral::DWT`
|
= note: perhaps two different versions of crate `cortex_m` are being used?Dependencies
The important parts of my Cargo.toml look like this:
[dependencies]
cortex-m = "0.6.2"
cortex-m-rt = "0.6.12"
panic-halt = "0.2.0"
[dependencies.f3]
features = ["rt"]
version = "0.6.1"
