# Migrating from v0.4.x to v0.5.0

# Migration of RTIC
|
||||
|
||||
## Migrating from v0.5.x to v0.6.0
|
||||
|
||||
This section describes how to upgrade from v0.5.x to v0.6.0 of the RTIC framework.
|
||||
|
||||
### `Cargo.toml` - version bump
|
||||
|
||||
Change the version of `cortex-m-rtic` to `"0.6.0"`.
|
||||
|
||||
### Module instead of Const
|
||||
|
||||
With the support of attributes on modules the `const APP` workaround is not needed.
|
||||
|
||||
Change
|
||||
|
||||
``` rust
|
||||
#[rtic::app(/* .. */)]
|
||||
const APP: () = {
|
||||
[code here]
|
||||
};
|
||||
```
|
||||
|
||||
into
|
||||
|
||||
``` rust
|
||||
#[rtic::app(/* .. */)]
|
||||
mod app {
|
||||
[code here]
|
||||
}
|
||||
```
|
||||
|
||||
Now that a regular Rust module is used it means it is possible to have custom
|
||||
user code within that module.
|
||||
Additionally, it means that `use`-statements for resources etc may be required.
|
||||
|
||||
### Init always returns late resources
|
||||
|
||||
In order to make the API more symmetric the #[init]-task always returns a late resource.
|
||||
|
||||
From this:
|
||||
|
||||
``` rust
|
||||
#[rtic::app(device = lm3s6965)]
|
||||
mod app {
|
||||
#[init]
|
||||
fn init(_: init::Context) {
|
||||
rtic::pend(Interrupt::UART0);
|
||||
}
|
||||
[more code]
|
||||
}
|
||||
```
|
||||
|
||||
to this:
|
||||
|
||||
``` rust
|
||||
#[rtic::app(device = lm3s6965)]
|
||||
mod app {
|
||||
#[init]
|
||||
fn init(_: init::Context) -> init::LateResources {
|
||||
rtic::pend(Interrupt::UART0);
|
||||
|
||||
init::LateResources {}
|
||||
}
|
||||
[more code]
|
||||
}
|
||||
```
|
||||
|
||||
### Resources struct - #[resources]
|
||||
|
||||
Previously the RTIC resources had to be in in a struct named exactly "Resources":
|
||||
|
||||
``` rust
|
||||
struct Resources {
|
||||
// Resources defined in here
|
||||
}
|
||||
```
|
||||
|
||||
With RTIC v0.6.0 the resources struct is annotated similarly like
|
||||
`#[task]`, `#[init]`, `#[idle]`: with an attribute `#[resources]`
|
||||
|
||||
``` rust
|
||||
#[resources]
|
||||
struct Resources {
|
||||
// Resources defined in here
|
||||
}
|
||||
```
|
||||
|
||||
In fact, the name of the struct is now up to the developer:
|
||||
|
||||
``` rust
|
||||
#[resources]
|
||||
struct whateveryouwant {
|
||||
// Resources defined in here
|
||||
}
|
||||
```
|
||||
|
||||
would work equally well.

||||

||||

||||

||||
