Portal CP70
7" - 800x400 Color Touch Display with Graphics Co-Processor
- Overview
- Commands
- Samples
- On-Module Code
A 7" 800×400 full-color touch display with an on-board BT817Q graphics coprocessor. The coprocessor handles rendering — drawing primitives, font work, and image blits — so the host commands a high-level draw pipeline with simple text commands over any supported interface, rather than pushing pixels itself.
Optional capacitive multi-touch is available, so the same module reads back finger positions for interactive UIs.
Common uses: industrial control panels, kiosk displays, point-of-sale interfaces, in-vehicle data screens, and custom embedded GUIs.
Because the BT817Q has its own command set, Portal CP70 doesn't use the engine's Graphics library — see the Commands tab for the supported draw primitives.

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.
| Function | Description |
|---|---|
Init(w, h, b) | Initialize display with width w, height h, and brightness b (0–100). |
DrawPixel(c, x, y) | Draw a pixel at (x,y) with color c. |
DrawLine(c, x, y, m, n) | Draw a line from (x,y) to (m,n) with color c. |
DrawCircle(c, x, y, r, f) | Draw a circle at (x,y) with radius r, color c. f=1 filled, f=0 outline. |
DrawRect(c, x, y, w, h, f) | Draw a rectangle at (x,y) with size w×h, color c. f=1 filled, f=0 outline. |
DrawString(b0, c, x, y, f, o) | Draw text from byte array b0 at (x,y) with color c, font f, and character offset o. |
ClearScreen(c) | Clear the screen with color c. |
FlushScreen() | Execute display list and update the screen. |
UpdTouch() | Update touch. Read _x and _y for touch x,y. |
DVer() | Return 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.
