COMMON DAISY DEVELOPMENT PATTERNS

Pattern 1: Basic Hardware Initialization

#include "daisy_seed.h"  // or daisy_pod.h, daisy_patch.h, etc.
#include "daisysp.h"

using namespace daisy;
using namespace daisysp;

DaisySeed hw;  // Or DaisyPod, DaisyPatch, etc.

int main(void)
{
    // Configure and initialize hardware
    hw.Configure();
    hw.Init();
    hw.SetAudioBlockSize(4);  // Optimize latency vs CPU load

    float sample_rate = hw.AudioSampleRate();

    // Initialize DSP modules here

    // Start audio
    hw.StartAudio(AudioCallback);

    while(1) {
        // Main loop for non-audio tasks (display updates, etc.)
    }
}

Pattern 2: Audio Callback Structure

void AudioCallback(AudioHandle::InterleavingInputBuffer  in,
                   AudioHandle::InterleavingOutputBuffer out,
                   size_t                                size)
{
    // Process controls (if needed)
    hw.ProcessAllControls();

    // Audio processing loop
    for(size_t i = 0; i < size; i += 2)
    {
        // Process left channel
        float in_l = in[i];
        float out_l = ProcessAudio(in_l);
        out[i] = out_l;

        // Process right channel
        float in_r = in[i + 1];
        float out_r = ProcessAudio(in_r);
        out[i + 1] = out_r;
    }
}

Pattern 3: Non-Interleaving Audio (Patch, Field)

void AudioCallback(AudioHandle::InputBuffer  in,
                   AudioHandle::OutputBuffer out,
                   size_t                    size)
{
    hw.ProcessAllControls();

    for(size_t i = 0; i < size; i++)
    {
        // Separate buffers for each channel
        float in_l = in[0][i];
        float in_r = in[1][i];

        // Process...

        out[0][i] = out_l;
        out[1][i] = out_r;
    }
}

Pattern 4: Parameter Mapping with Smoothing

Parameter freq_param;
float     freq_target, freq_current;

// In initialization:
freq_param.Init(hw.knob1, 20.f, 20000.f, Parameter::LOGARITHMIC);

// In audio callback:
freq_target = freq_param.Process();
fonepole(freq_current, freq_target, 0.0001f);  // Smooth parameter
osc.SetFreq(freq_current);

Pattern 5: SDRAM Buffer Allocation

#define MAX_DELAY 96000

// Place delay buffer in SDRAM
DelayLine<float, MAX_DELAY> DSY_SDRAM_BSS delay;

// In initialization:
delay.Init();
delay.SetDelay(48000);  // 1 second at 48kHz

Pattern 6: Multi-Effect Chain

ReverbSc reverb;
Chorus   chorus;
Overdrive drive;
bool     effect_on[3];

void AudioCallback(...)
{
    for(size_t i = 0; i < size; i += 2)
    {
        float sig = in[i];

        // Chain effects
        if(effect_on[0]) sig = drive.Process(sig);
        if(effect_on[1]) sig = chorus.Process(sig);
        if(effect_on[2]) {
            float wet_l, wet_r;
            reverb.Process(sig, sig, &wet_l, &wet_r);
            sig = (sig + wet_l) * 0.5f;
        }

        out[i] = sig;
        out[i+1] = sig;
    }
}

Pattern 7: CV Input (V/Oct Pitch Control)

// In patch_sm or patch:
float cv_input = patch.GetAdcValue(CV_5);
float voltage = fmap(cv_input, 0.f, 5.f);  // 0-5V range
float midi_note = base_note + (voltage * 12.f);  // V/Oct conversion
float freq = mtof(midi_note);  // MIDI to frequency
osc.SetFreq(freq);

Pattern 8: Switch with Debouncing

hw.ProcessDigitalControls();

if(hw.button1.RisingEdge())
{
    // Button just pressed
    effect_on = !effect_on;
}

if(hw.button1.FallingEdge())
{
    // Button just released
}

if(hw.button1.Pressed())
{
    // Button currently held
}

TROUBLESHOOTING GUIDE

Issue: Code doesn't compile

Diagnostic Path:

Check header includes match hardware platform
Verify LIBDAISY_DIR and DAISYSP_DIR in Makefile
Ensure libraries are built (./ci/build_libs.sh)
Check for typos in DaisySP module names
Verify toolchain installed correctly

Issue: Audio dropouts/clicking

Diagnostic Path:

Reduce audio block size if latency not critical
Simplify DSP processing in callback
Remove any printf/logging from audio callback
Check for division by zero or NaN
Profile CPU usage (should be <80%)
Move non-critical processing to main loop

Issue: No audio output

Diagnostic Path:

Verify StartAudio() called with correct callback
Check audio callback function signature
Confirm DSP modules initialized with sample rate
Verify output buffer being written
Test with simple passthrough or sine wave
Check hardware connections

Issue: Parameters not responding

Diagnostic Path:

Call ProcessAllControls() or ProcessAnalogControls()
Verify ADC started with StartAdc() if needed
Check parameter mapping ranges
Test ADC values with serial logging
Confirm correct knob/CV index used

Issue: Program won't upload

Diagnostic Path:

Enter bootloader mode (BOOT + RESET)
Check USB connection
Verify programmer tool installed (dfu-util)
Try make program-dfu vs make program
Check for proper .bin file in build/

Issue: Running out of memory

Diagnostic Path:

Move large buffers to SDRAM with DSY_SDRAM_BSS
Reduce delay line sizes if possible
Use shorter audio block sizes
Check linker map file for memory usage
Avoid large stack allocations in audio callback

BEST PRACTICES

1. Audio Callback Dos and Don'ts

DO:

Keep processing as simple as possible
Use hardware FPU (float math is optimized)
Pre-calculate constants outside callback
Use inline functions for small utilities
Process controls at control rate (not every sample)

DON'T:

Call printf() or any I/O
Allocate memory (malloc/new)
Use unbounded loops
Call blocking functions
Access slow peripherals

2. Parameter Smoothing

Always smooth parameter changes to avoid zipper noise:

fonepole(current, target, coefficient);  // Exponential smoothing
// Smaller coefficient = slower response

3. Memory Management

Use DSY_SDRAM_BSS for buffers > 50KB
Keep critical variables in SRAM
Static allocation preferred over dynamic
Mind the stack size in audio callback

4. Code Organization

Separate initialization from processing
Use descriptive function names
Group related functionality
Keep audio callback lean

5. Testing Strategy

Start with simple passthrough
Add one effect/feature at a time
Test parameter ranges thoroughly
Monitor CPU usage
Verify behavior at extremes
