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

Improve ROM function access
 2022-02-04 09:53:59 +00:00
Derek Hageman a6daaf9fa3 Standardize ROM function access 
Make all ROM functions (normal and floating point) provide both a direct
call that does the operation and a module with a ptr() function to get
the function pointer.

Implements methods to allow presetting the pin state & direction (#167) 
* Implements methods to allow presetting the pin state & direction

Enabling those methods allows to save a few valuable instructions
in the PIO's memory.

* Update pio_proc_blink with new set_pindirs

Mathias Gottschlag 207f5aebdb pio: Split RX and TX FIFO functions into different types. 
We need separate types for any blocking or DMA operations - otherwise, it
would not be possible to perform both RX and TX transfers at the same time.
