Normally they support writing RGB666, RGB565 or RGB444 after a few init commands.
I usually use RGB565 as it fits 1 pixel in 2 bytes, making writes faster and I often don’t need the extra colour precision of RGB666.

Nice! I'll update the driver with support for this display.

Give this a try: i2c = I2C(sda=Pin("Y8"), scl=Pin("Y6")) display = ssd1327.SSD1327_I2C(128, 128, i2c) # Unlock display.write_cmd(0xFD) display.write_cmd(0x12) # Display off display.write_cmd(0xAE) # Set column address 0-127 display.write_cmd(0x15) display.write_cmd(0x00) # was 0x08 on 96x96 ((128-wi...

Should be an easy fix with some init registers. I’ll take a look at some of the Arduino drivers and let you know what needs to change

If you have that DevEBox board, that little W25Q16 chip above the micro SD slot is the 16MB SPI Flash. It's wired to SPI1, leaving SPI2 and 3 free for use by other devices. It's CS pin is exposed on A15, so you could have other SPI devices on the SPI1 bus.

On the F411 board , I demonstrated in the readme attaching an external W25Q128 16MB SPI flash module. The particular breakout I was using only supported SPI mode, instead of the faster QSPI mode. Still, 4, 8 or 16MB more to play with. In mpconfigboard.h you can toggle between using the onboard flash...

It fits on my ESP8266 (4MB Wemos D1 Mini) running MicroPython v1.12-337, on both FAT and Littlefs v2 The mcp23017.py file takes up 16k. If I convert all those spaces to tabs, it takes up 13k. Cross compile it and upload as mcp23017.mpy and it takes up 4k. from machine import Pin, I2C import mcp23017...

I have an ESP8266 handy. I'll try to make it fit.
Those pins are fine for I2C, however, you'll need some pull ups.
Consider using D3 and D4 as they already have 10k's (to set the correct boot mode). Side effect is, D4 is also used by the LED so it will flicker on data. Maybe use it for the I2C clock.

Hi @dentex, While creating the driver, I came up with 3 interfaces and I was going pick the most useful and maybe retire the others, or make alternate versions, so you can pick the one that works best for your needs. 1. The list interface, where each item represents a pin and has methods for reading...

Here it is:

0x3c is decimal 60.

If you want to use two of these displays on the same i2c bus, check if the oled module has any address select resistors on the back.
