- probe-run screwed up the last release 2 weeks ago and it's still not fixed (issue 391). Doesn't look well maintained.
- Even when it's not broken, it lags behind probe-rs-cli in new chips support because it's slow in updating probe-rs.
inline assembly is supported since rust 1.59, we're way past that.
enabling this makes the compiled code more compact, and on rp2040
even decreses memory usage by not needing thunks in sram.
This introduces a `Pender` struct with enum cases for thread-mode, interrupt-mode and
custom callback executors. This avoids calls through function pointers when using only
the thread or interrupt executors. Faster, and friendlier to `cargo-call-stack`.
`embassy-executor` now has `arch-xxx` Cargo features to select the arch and to enable
the builtin executors (thread and interrupt).
- Allows classes to handle vendor requests.
- Allows classes to use a single handler for multiple interfaces.
- Allows classes to access the other events (previously only `reset` was available).
The eth code is always built and available, but has no own API (other
than the embassy-net Device impl) to rx/tx packets. We could add this
API in the future, so the feature only means "embassy-net support".
1025: Implement I2C timeouts, second attempt r=Dirbaio a=chemicstry
This is an alterrnative to #1022 as discussed there.
Timeouts are implemented using suggested `check_timeout: impl Fn() -> Result<(), Error>` function, which does not depend on `embassy-time` by default and is a noop for regular I2C.
This also adds `time` feature like in `embassy-nrf` to enable `embassy-time` dependencies. While at it, I also gated some other peripherals that depend on `embassy-time`, notably `usb` and (partially) `subghz`.
`TimeoutI2c` is currently only implemented for i2cv1, because i2cv2 has additional complications:
- Async methods still use a lot of busy waiting code in between DMA transfers, so simple `with_timeout()` will not work and it will have to use both types of timeouts. It could probably be rewritten to replace busy waits with IRQs, but that's outside the scope of this PR.
- I2C definition `I2c<'d, T, TXDMA, RXDMA>` is different from i2cv1 `I2c<'d, T>` making it hard to share single `TimeoutI2c` wrapper. A couple of options here:
- Duplicate `TimeoutI2c` code
- Add dummy `TXDMA`, `RXDMA` types to i2cv1 considering that in the future it should also support DMA

It was only useful for doing #[embassy_executor::main(config = "config()")]`. Now that
it's gone, it makes more sense to build the config in main directly.
896: Implement I2C pullup configuration r=lulf a=chemicstry
I wasn't sure if I should put frequency into config struct, so left it separate as in SPI periph.
Also added Copy derives to gpio types, not sure why they weren't?
