Adding OLED to Pod?

StaffanMelin · December 17, 2021, 9:15pm

Hello @moonfriend and welcome to the forum!

Congrats on building your own pod! Like you, I can’t afford the larger Daisys so I work with the Seed and an LCD screen:

If you attach on OLED you can use the OLED support in libdaisy:

github.com

electro-smith/libDaisy/blob/master/src/dev/oled_ssd130x.h

#pragma once
#ifndef SA_OLED_SSD130X_H
#define SA_OLED_SSD130X_H /**< & */

#include "per/i2c.h"
#include "per/spi.h"
#include "per/gpio.h"
#include "sys/system.h"

namespace daisy
{
/**
 * I2C Transport for SSD1306 / SSD1309 OLED display devices
 */
class SSD130xI2CTransport
{
  public:
    struct Config
    {
        Config()

Look at the init source for the Daisy Patch to see how it is used:

github.com

electro-smith/libDaisy/blob/master/src/daisy_patch.cpp

#include "daisy_patch.h"
#include "dev/codec_ak4556.h"

using namespace daisy;

// Hardware Definitions
constexpr Pin PIN_ENC_CLICK  = seed::D0;
constexpr Pin PIN_ENC_B      = seed::D11;
constexpr Pin PIN_ENC_A      = seed::D12;
constexpr Pin PIN_OLED_DC    = seed::D9;
constexpr Pin PIN_OLED_RESET = seed::D30;
constexpr Pin PIN_MIDI_OUT   = seed::D13;
constexpr Pin PIN_MIDI_IN    = seed::D14;
constexpr Pin PIN_GATE_OUT   = seed::D17;
constexpr Pin PIN_GATE_IN_1  = seed::D20;
constexpr Pin PIN_GATE_IN_2  = seed::D19;
constexpr Pin PIN_SAI_SCK_A  = seed::D28;
constexpr Pin PIN_SAI2_FS_A  = seed::D27;
constexpr Pin PIN_SAI2_SD_A  = seed::D26;
constexpr Pin PIN_SAI2_SD_B  = seed::D25;

Method InitDisplay().

Then you can study an example for the Daisy Patch to see how to use it eg:

github.com

electro-smith/DaisyExamples/blob/master/patch/vco/ex_vco.cpp

#include "daisysp.h"
#include "daisy_patch.h"
#include <string>

using namespace daisy;
using namespace daisysp;

DaisyPatch patch;
Oscillator osc;
Parameter  freqctrl, wavectrl, ampctrl, finectrl;

static void AudioCallback(AudioHandle::InputBuffer  in,
                          AudioHandle::OutputBuffer out,
                          size_t                    size)
{
    float  sig, freq, amp;
    size_t wave;

    patch.ProcessAnalogControls();

As I have only worked with LCDs myself, I can’t really give you more help, but this is how I would do it!
