There are a lot of non-binary crates depending on rp2040-hal. That way,
the default-features of rp2040-hal may be activated unintentionally
through an indirect dependency. Therefore, a binary crate which wants
to disable the `critical-section-impl` feature to provide its own one
could have a hard time to do so.
In contrast, the board support crates are usually only used by top-level
binary crates. So disabling the default features on those should usually
just work.
Binary crates depending on rp2040-hal directly, which don't use any
board support crate, might need to activate the feature manually. This
is reasonable because those binary crates need to replicate some
boilerplate from the board crates anyhow.
This is a little bit hacky, as it relies on rp2040-hal actually
using (and therefore linking) some defmt code when the defmt feature is
enabled.
However this solution has the advantage that it only affects
dev-dependencies and therefore has no impact on the board crates
themselves.
Closes#420
Current version of probe-run is 0.3.3, which uses defmt 0.3.2.
With a firmware using defmt 0.2, this causes the following error
message:
```
Error: defmt wire format version mismatch: firmware is using 0.2, `probe-run` supports 3
suggestion: `cargo install` a different version of `probe-run` that supports defmt 0.2
```
Therefore, upgrade defmt dependency, and also fix the linker script
in .cargo/config.
* Update BSP README's to use current version number
* Update ws2812-pio and i2c-pio to release 0.3.0
* Bump patch number for BSPs so we can push with correct docs
* Update changelog, readme and version number for HAL 0.5.0 release
* Bump HAL version in BSP deps
* Point ws2812-pio and i2c-pio-rs at hal_0.5.0 branches
* Update changelog with latest commits and release date
* Add the Pimoroni Plasma 2040 board
This PR adds the board support package and a simple example.
The example just blinks the on-board RGB LED.
An example should be added for using the board to control an LED strip.
This should probably use smart-leds with the associated PIO driver.
An example or functionality should be added for the current sensor.
* Rename LED data line from dat to data to match schematic
* Add an example for driving WS2812 LEDs
This is pretty much a copy-paste of the awesome pico_ws2812_led example.
* Remove reference in README to rp-pico
* Remove reference to pico board clock speed
I have removed this in the Plasma 2040 repository and where I copied it from, tiny2040_blinky.
* Remove redundant namespace
* Add self-reference in README to the current board's GitHub README
Fix the erroneous link in the pimoroni-tiny2040 README from which I copied.
