Hi everyone,

I’d like to share a display solution that we recently integrated into a flight simulator cockpit panel project. For applications like instrument clusters and control dashboards, having a square, high-brightness LCD can make the interface much more efficient and immersive.

We used an 8.82-inch LVDS square TFT LCD (768x768 resolution), which provides sharp image quality and a wide viewing angle—ideal for simulator environments where multiple instruments are displayed simultaneously.

The panel works seamlessly with LVGL for custom UI layouts, and its square format fits perfectly into compact cockpit panels without wasting screen space.

If anyone here is working on flight simulation dashboards or similar projects and needs a reliable, industrial-grade LCD, feel free to reach out or exchange ideas.

This forum is about Teensy. We're fine with a lot of conversations about electronic stuff in general. But if you're just advertising your display and its electronics without any sort of application to people building electronic projects with Teensy, then you'll be considered a spammer and permanently banned.

Write 1 more message to show us you're here to be part of a meaningful conversation rather than just advertising your display that has nothing to do with Teensy.
 
Teensy boards don’t have native HDMI output, so you can’t directly connect a Teensy to an HDMI driver board to run the 8.82-inch square LCD display. The most practical way to make this work is to use a hybrid setup with a Raspberry Pi (or similar SBC) acting as the HDMI video source, while the Teensy handles I/O and control tasks.

In this setup, the Teensy is responsible for handling sensors, switches, encoders, and real-time control tasks, such as cockpit inputs in a flight simulator. The Raspberry Pi (or another SBC) runs LVGL or a custom UI application, generates the graphical interface, and outputs it through HDMI. The HDMI driver board then converts the HDMI signal to LVDS to drive the 8.82-inch square LCD display with a resolution of 768×768.

This architecture is widely used in flight simulator panels, instrument clusters, and similar applications where the UI rendering is separated from real-time control logic. Teensy excels at precise input handling, while the Raspberry Pi provides the graphics power needed to drive a high-resolution HDMI display.

In this approach, the Teensy and Raspberry Pi work together seamlessly. The Teensy collects data and sends it to the Pi through USB or serial, the Pi updates the display in real time via HDMI, and the LCD is powered and driven by the HDMI driver board. This method doesn’t require any custom HDMI generation on the Teensy side and offers a stable, practical solution for long-term use.

Thats great, but how did you wire it to a Teensy?

Hi,

I did this in my Teensy 4.1 ISFD flightsimulator project in the past.....i used an EVE4 chip as "SPI/RGB Gateway". The EVE4 chip has a kind of opengl language which you control via SPI Interface which is feeded by the Teensy. Performance of the Teensy is outstanding here. It calculates everything in no time...i can achive up to 100 Hz of refresh rate. On the display side the EVE has an RGB 8/8/8 Interface...
On the pictures you can see the 3ATI variant, which would also fit into the real ones....

I was excitged to see a larger display but just throwing a link over that wall to a drawing is not useful to most of us.

1. are the libraries to drive this display?
2. is there a recommended / required communication path between Teensy and RPI?
3. Are there examples in getting this display to work?

The posts by @Cuble1998, all posted very closely together in time, seem very bot-like, but I'd like to be either very right or very wrong with that guess. So, as an attempt to make sure that you are human, please post a reply with an intentionally false statement, enclosed in quotes, and/or with a single, intentional misspelling of a common word, but enclose that word only in quotes so that it is easy to identify.

Waiting . . .

It's been marked as spam. This is the only remaining message of "Her's".
 
The exact same post was posted on lvgl’s forum
Seems like a poor marketing attempt to the wrong target audience

Why go to the trouble of connecting this up to a Pi via an LVDS-HDMI converter, to then use the teensy just for data acquisition when you can do that on the Pi?

Just get a smart display and control some of the UI components via Serial.
