Combine OLED and read analogue objects

[justinjools]

I want to combine OLED and read analogue code using Patch SM. I have working examples for OLED and reading potentiometer.

The OLED example uses DaisySeed hw object and the Pot example uses DaisyPatchSM patch.

I have tried to modify the DaisyPatchSM to use the DaisySeed hw example but it tells me it doesn’t have hw.Configure() member.

Conversely I have tried to modify DaisySeed hw patch to DaisyPatchSM but the patch.GetAdcValue(CV_1); doesn’t work.

It also seems I cannot run two different Initialise objects: hw.Init(), patch.Init();

How can I add OLED and read ADC pot for Patch SM?

OLED example

#include <stdio.h>
#include <string.h>
#include “daisy_seed.h”
#include “dev/oled_ssd130x.h”

using namespace daisy;
using MyOledDisplay = OledDisplay;

DaisySeed hw;
MyOledDisplay display;

int main(void)
{
uint8_t message_idx;
hw.Configure();
hw.Init();

MyOledDisplay::Config disp_cfg;
display.Init(disp_cfg);

message_idx = 0;
char strbuff[128];
while(1)
{
    System::Delay(500);
    switch(message_idx)
    {
        case 0: sprintf(strbuff, "Testing. . ."); break;
        case 1: sprintf(strbuff, "Daisy. . ."); break;
        default: break;
    }
    message_idx = (message_idx + 1) % 5;
    display.Fill(false);
    display.SetCursor(0, 0);
    display.WriteString(strbuff, Font_11x18, true);
    display.Update();
}

}

Read Pot

#include “daisy_patch_sm.h”
#include “daisysp.h”

using namespace daisy;
using namespace patch_sm;
using namespace daisysp;

DaisyPatchSM patch;

int main(void)
{
patch.Init();
patch.StartLog(true);

while(1)
{
    patch.ProcessAllControls();

    float value = patch.GetAdcValue(CV_1);
    patch.PrintLine("My Float: %f", value);
    System::Delay(200);
}

}

I think you need hw.StartAdc(); before reading any ADC values.

On patch_sm, StartAdc is done in Init().
