TFT R128
1.28" - 240x240 Color Round Display
- Overview
- Commands
- Samples
- On-Module Code
A 1.28" 240×240 round color TFT display — circular form factor for projects where a square screen would look out of place. Render text and graphics with simple text commands over any supported interface, using the engine's Graphics library.
Common uses: smartwatch-style projects, custom analog gauges, knob faces, status orbs, and any design where the round shape becomes part of the visual identity.

Modules ship without cables to reduce waste. Some specialty boards include a USB cable; for the rest, see Cables to add cables to your order.
Commands this module accepts. See Samples for runnable code in popular host languages.
The commands below set the display up. To draw on it, use the engine's built-in Graphics library — the same drawing functions (Line, Text, Rect, Show, etc.) render to any display in the DUELink catalog, so the same drawing code works no matter which display you have connected.
| Function | Description |
|---|---|
Init(m) | Initialize the display. Automatically called on power up mmode to (1-direct, 0-buffered (default)). |
GetW() | Get display width: 80 in buffered, 240 in direct. |
GetH() | Get display height: 80 in buffered, 240 in direct. |
IsColor() | Returns 1. |
DVer() | This driver version. |
Peek under the hood
The script below is this module's driver — it teaches the hardware how to respond to the commands listed above. It ships pre-loaded from the factory; most users never need to open it.

This sample runs in MicroBlocks on a any host board that's connected/tethered to this module, or a chain of modules. This module keeps its official DUELink firmware and module driver and responds to commands from the connected MicroBlocks-running host. New here? See the MicroBlocks page.
There are two ways to use it:
Open the full sample — the complete project (the module's library plus a ready-to-run example) opens directly on the MicroBlocks website.
Add just the libraries to your own project — copy the link, then in your MicroBlocks project click Add Library → Cloud and paste it. This loads this module's libraries into your project without replacing your current work.
Copy Library LinkCode that runs directly on this module's MCU. See how On-Module Code allows modules to run standalone.
- Script
- Arduino IDE
This example runs using the default DUELink Internal Engine using its Scripting Language, and it expects the module's driver to be loaded first, see the Commands Tab.
