The screen has memory to store the picture, so you can directly send data through USB, data format is R-G-B-R-G-...in SDK the API has packaged all necessary functions, please also check the demo of DOOM to study how it works.
Current version support framebuffer driver(obsolete), drm driver(depends linux kernel version) or libusb(recommend) for VoCore2 and Raspberry, please check https://github.com/Vonger/mpro_drm
The internal display glass of the screen is only 0.2mm ultra-thin. While the touch screen (1mm thick) is more durable, the corners of the internal glass are extremely fragile and can easily break due to external pressure, impact, or transportation vibration (Image: Internal glass breakage scenario).
Key Protection Points:
1. Do not press the screen surface or corners during installation, and avoid direct external force;
2. The enclosure design must provide full protection to prevent any pressure on the screen;
3. Ensure shockproof and buffer protection during transportation to avoid breakage from severe shaking;
4. For more details to refer: Screen: Glass is really easy to break…
