Public Attributes Documentation¶

variable cv_change_filt¶

CvChangeFilter cv_change_filt[2];

Simple filters for CV inputs to only output values when they have changed

variable hw¶

Hardware hw;

Global Hardware object

variable msg_fifo¶

FIFO<FixedCapStr<32>, 16> msg_fifo;

FIFO of strings that we can use to move messages from the Audio callback to be printed in the main while() loop.

variable prev_toggle_pos¶

int prev_toggle_pos;

state of 3-way toggle for output when changed

variable ui¶

Ui ui;

Global UI object

Public Functions Documentation¶

function AudioCallback¶

void AudioCallback (
    AudioHandle::InputBuffer in,
    AudioHandle::OutputBuffer out,
    size_t size
)

function LowPriorityCallback¶

void LowPriorityCallback (
    void * data
)

This callback happens every 4ms (250Hz) and can be interrupted by everything except for the SysTick interrupt. The frequency of this callback is set in the Hardware::StartLowPriorityCallback parameters.

Handling the UI events here means that anything we do in the main while() loop that may take an indeterminate time (file system I/O, QSPI Saving, etc.) won't cause the UI to stall during those processes

function main¶

int main (
    void
)
