Struct SequenceBuilder

pub struct SequenceBuilder { /* private fields */ }

A Sequence builder

Use SequenceBuilder to define a FlexSPI LUT sequence. If you insert too many instructions into the sequence, you’ll observe a compile-time error.

Any unspecified instructions are set to STOP.

Example

use imxrt_boot_gen::flexspi::{
    Sequence,
    SequenceBuilder,
    Instr,
    Pads,
    opcodes::sdr::*,
};

const SEQ_READ: Sequence = SequenceBuilder::new()
    .instr(Instr::new(CMD, Pads::One, 0xEB))
    .instr(Instr::new(READ, Pads::Four, 0x04))
    .build();

Implementations

impl SequenceBuilder

pub const fn new() -> Self

Creates a new SequenceBuilder than can accept up to eight instructions

All unspecified instructions are set to STOP.

pub const fn instr(self, instr: Instr) -> Self

Insert instr as the next sequence instruction

If you call instr more than 8 times, you’ll observe a compile-time error.

pub const fn build(self) -> Sequence

Create the sequence

Trait Implementations

impl Default for SequenceBuilder

fn default() -> Self

Returns the “default value” for a type.
