Hi all!  
I need implementation of OLED1306ASCII library in XOD

for use with low memory boards  
Can anybody help?

[wayland/ssd1306-oled-i2c — XOD](https://xod.io/libs/wayland/ssd1306-oled-i2c/) library already exists, but it wraps Adafruit\_SSD1306 ([GitHub - adafruit/Adafruit\_SSD1306: Arduino library for SSD1306 monochrome 128x64 and 128x32 OLEDs](https://github.com/adafruit/Adafruit_SSD1306)), so it might use too much memory for you. You might be able to use it as a template for creating your own wrapper for the ASCII library even if it doesn’t work for you.

i tried using instruction but kept getting error

error: no matching function for call to ‘SSD1306AsciiAvrI2c :: SSD1306AsciiAvrI2c (const DevType \*, uint8\_t &)’  
Type oled = new (mem) SSD1306AsciiAvrI2c (& Adafruit128x64, i2cAddr)

Do you have pragma to include the SSD1306Ascii library? That is where that function should be defined. There are general instructions for wrapping IDE libraries [Wrapping Class-based Arduino Libraries — XOD](https://xod.io/docs/guide/wrapping-arduino-libraries/), and the wayland library I linked to above will probably be pretty close to what you want, making it a good template/example.

I’m afraid I can’t help you much beyond that since I don’t have experience with the process.

of course  
trouble in → Type oled = new (mem) SSD1306AsciiAvrI2c(&Adafruit128x64, i2cAddr);

#pragma XOD require “[GitHub - greiman/SSD1306Ascii: Text only Arduino Library for SSD1306 OLED displays](https://github.com/greiman/SSD1306Ascii/)”

#include “SSD1306Ascii.h”  
#include “SSD1306AsciiAvrI2c.h”

node {  
meta {  
using Type = SSD1306AsciiAvrI2c\*;  
}

```
uint8_t mem[sizeof(SSD1306AsciiAvrI2c)];
void evaluate(Context ctx) {
    if (!isSettingUp())
        return;
    uint8_t i2cAddr = getValue<input_ADDRESS>(ctx);
    Type oled = new (mem) SSD1306AsciiAvrI2c(&Adafruit128x64, i2cAddr);

    emitValue<output_DEV>(ctx, oled);
}

```

};
