Implementations

impl<const PROGRAM_SIZE: usize> Assembler<PROGRAM_SIZE>

pub fn new() -> Assembler<PROGRAM_SIZE>

Create a new Assembler.

pub fn new_with_side_set(side_set: SideSet) -> Assembler<PROGRAM_SIZE>

Create a new Assembler with SideSet settings.

pub fn assemble(self) -> ArrayVec<u16, PROGRAM_SIZE>

Assemble the program into PIO instructions.

pub fn version(&self) -> PioVersion

Check the program for instructions and operands available only on the RP2350.

pub fn assemble_program(self) -> Program<PROGRAM_SIZE>

The program contains the instructions and side-set info set. You can directly compile into a program with correct wrapping with Self::assemble_with_wrap, or you can set the wrapping after the compilation with Program::set_wrap.

pub fn assemble_with_wrap( self, source: Label, target: Label, ) -> Program<PROGRAM_SIZE>

Takes pair of labels controlling the wrapping. The first label is the source (top) of the wrap while the second label is the target (bottom) of the wrap. The source label should be positioned after the instruction from which the wrapping happens.
