Remove some unused fields from UartPeripheral and Reader (#315)
* Remove unused field `effective_baudrate` from uart code

* Remove unused field `config` from uart code

Using thread send safe UART* marker, as suggested by @danielzfranklin in #Issue-284 (#314) 2022-03-18 20:56:27 +11:00

Allow to start multiple state machines in sync (#301)
* add example of synchronized PIOs

* Synchronize state machines using WAIT IRQ instruction

* Use "irq wait 0" instead of "wait 1 irq 0"

This way, the initial value of the interrupt flag doesn't matter

* Start state machines synchronized without IRQ WAIT instruction

* Improve API

Add an rp2040 specific #[entry] macro. (#300)
* Add an rp2040 specific #[entry] macro.

This macro extends the one from cortex-m-rt by code to unlock
all spinlocks on boot.

* Idiomatic pointer arithmetic

Apply suggestion by @9names, improving address calculations.
(This doesn't change the generated code at opt levels 2 or "z".)

Jan Niehusmann 402b7f1eb8 Use u32 instead of u64 division in clock calculations
This saves about 1kB of flash by removing
compiler_builtins::int::specialized_div_rem::u64_div_rem if
no other code uses u64 divisions.
