Currently, only 128x32 and 128x64 variants are supported. These displays usually have an I²C address of `0x3c`.
Some displays can be used with both I²C and SPI interfaces and may need to be reconfigured by setting some resistors on the back of the assembly. `mt32-pi` currently only supports I²C displays, so read your display's documentation to learn how to put it into I²C mode.
This driver should also work with SSD1309 displays such as the [Diymore 2.42" OLED][2.42" OLED], but the display may need some small modifications to ensure it is in I²C mode, that the address is correct, and to deal with any reset signals.
### Compatibility
The following displays and configurations have been confirmed as working by our testers. Please note the necessary configuration file options.
| Manufacturer | Device | Config file options | Comments |
|----------------|-----------------|----------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------|
| BuyDisplay.com | [2002-1 Series] | `type = hd44780_i2c`, `width = 20`, `height = 2`, `i2c_lcd_address = 27` | Very bright and inexpensive 20x2 LCD. Tested by @dwhinham. |
| Generic | [128x32 OLED] | `type = ssd1306_i2c`, `width = 128`, `height = 32`, `i2c_lcd_address = 3c` | Extremely cheap yet nice and bright mini OLED. Widely available on AliExpress and eBay. Tested by @dwhinham. |
| Generic | [128x64 OLED] | `type = ssd1306_i2c`, `width = 128`, `height = 64`, `i2c_lcd_address = 3c` | Similar to the 32 pixel high OLED, just with more rows. Tested by @dwhinham. |
| Raystar | [REC002004B] | `type = hd44780_4bit`, `width = 20`, `height = 4` | High-contrast 20x4 OLED display. Tested by @dwhinham. |
