Cache maintenance operations require reference to self

1

Various cache maintenance-related operations require a `self` reference, which means that it is not possible for a HAL or other peripherals to clean/invalidate and/or perform other cache related operations without...

Device registers cannot be displayed in a debugger

2

This issue is being moved after originally posted in https://github.com/rust-embedded/wg/issues/459 Because of the implementation of `svd2rust` (and some issues with trait implementations in the debug information outlined [here](https://github.com/rust-lang/rust/issues/33014)), register blocks...

Improved timer implementation

2

The existing timer implementation provides itself well to giving the user a generic `Countdown` or `Periodic` object that can be used for regularly completing tasks, but there is limited control...

Library panics when deserializing certain types due to `unreachable!()` statements

12

When deserializing certain types, the library may hit `unreachable!()` statements, which results in a panic. This appears to be because serde-json-core does not support deserializing complex enums (e.g. `pub struct...

select() may generate an identifier that is unusable

2

When using the `select()` function, the provided path cannot necessarily be used for a subsequent `select()` (or `getattr()`, etc) and will not properly select any items. This appears to arise...

Analyze low batch size timing

7

Analyze the timing requirements when using the DMA sample acquisition architecture for ADC/DAC operations for low batch sizes (e.g. 1 or 2). If possible, we may want to eliminate the...

When the batch size is equal to 1, the delay from INPUT -> OUTPUT appears to be 4 batches instead of 3. This is not true for batch sizes !=...

Measure run-time task load

4

As part of the stabilizer firmware, it has been brought up that it would be useful to be able to measure and report "task-load" for the various interrupt tasks in...

Store device identifier and broker in non-volatile memory

1

Currently, stabilizer generates an identifier using the binary name and MAC address. We should allow this default to be overridden by the user and the value should persist to non-volatile...

[Proposal] std-powered Clock implementation for tests

5

Many crates that want an `embedded_time::Clock` may also want to have integration/unit tests that run on host. Is it possible to expose a `std`-powered `embedded_time::Clock` that can be easily used...
