tinygo interfacing ssd1306 display troubleshooting

[ohchloeho]

I'm trying to interface an OLED display with an Arduino Nano through the TinyGo library. I've managed to flash the code below to my Nano multiple times however there isn't any response through the OLED display.

I'm certain I've setup the wiring correctly as I run some code through the Arduino IDE and the OLED display works as expected with the same wiring.

It would be great if anyone can help with this - I've researched various websites and I believe this could just be a configuration issue with TinyGo's SSD1306 module but I'm not sure about the fix.

My current code:

package main

import (
	"image/color"
	"machine"
	"time"
	"tinygo.org/x/drivers/ssd1306"
)

func main() {
	// Initialize I2C (using the default pins for Arduino Nano)
	i2c := machine.I2C0
	i2c.Configure(machine.I2CConfig{})

	// Initialize the OLED display with SSD1306 driver
	display := ssd1306.NewI2C(i2c)
	display.Configure(ssd1306.Config{
		Width:   128,
		Height:  64,
		Address: 0x3C, // Default I2C address for OLED
	})

	// Clear the display buffer
	display.ClearBuffer()

	// Turn on all the pixels by setting each one to 1 (on)
	for x := int16(0); x < 128; x++ {
		for y := int16(0); y < 64; y++ {
			display.SetPixel(x, y, color.RGBA{255, 255, 255, 255}) // Set each pixel to "white"
		}
	}

	// Send buffer to the display to update it
	display.Display()

	// Keep the display on
	for {
		time.Sleep(time.Second)
	}
}

I'm also using the Arduino Nano ATmega328P. I've tested the other pins with external LEDs and I'm certain they are working as well.

The source code looks fine. It might be a good idea to check the waveform using a logic analyzer.
