Merge pull request #269 from 9names/fix_uart_example_clock 
Use .freq() to avoid moving clock

Wilfried Chauveau d08bfac989 Fix i2c peripheral mode state machine 
The start_det flag is set as soon as a start condition occurs
whereas rd_req flag is only set once the address byte is received.

Derek Hageman f279945315 Add intrinsics for the hardware divider 
Implement intrinsic functions so basic operators use the hardware divider.
 2022-01-26 19:37:06 -07:00
Derek Hageman 35704d9799 Change divider delay to explicit NOPs 
Use explicit NOPs since cortex_m::asm::delay actually delays for
longer than we need to.

Update to pio-rs v0.1.0 (#239) 
* Update to PIO 0.1.0

* Update to latest ws2812-pio and i2c-pio.

These depend on pio 0.1.0, avoiding a conflict

* Rename CI tests.

Also check we can cargo build. And remove 'on host tests' that didn't
do anything.

Implement peripheral support for i2c and an advanced example (#162) 
* Implement peripheral support for i2c and an advanced example for the pico board.

* Simplify i2c peripheral bootstrap and add a "free" function to allow switching modes.

* Set dependency to futures & nostd_async to specific version/revision.

* move enum & struct to the start of the file

* Add a bit of documentation to the pico_i2c_controller_peripheral demo.

* Migrate to pico_i2c_controller_peripheral to embassy & simplify the peripheral support

nostd_async is broken since last stable roll out.
The pico_i2c_controller_peripheral is being migrated to use embassy's executor.
The Controller Async API is now aligned with embassy's traits to facilitate integration.

The peripheral no longer require async to run and now appears as an event iterator.

Embassy's support relies on unstable features (generic_associated_types and type_alias_impl_traits)
and is therefore gated behind the `embassy-traits` feature flag.

* make futures & embassy optional for the pico board too

* Pin embassy to a specific rev.

* Impl embassy_traits::i2c::WriteIter & enable unlimited transfer size on i2c

* Applies comment suggestion from @9names for the advanced i2c example.

Co-authored-by: 9names <60134748+9names@users.noreply.github.com>

* use `I2C block` instead of `IP`.

* Fix formatting (unnecessary space at end of line)

* Enhance explanation for why `rd_req()`  is not cleared in `Iterator::next`'s
implementation.
