# Minitela do Positivo Vision R15M: AHMI display protocol and ACF format

> Minitela do Positivo Vision R15M implements Linux tools for the laptop’s 240×240 secondary display. The project documents its AHMI serial frames and ACF texture container using vendor-app captures, synthetic-image output comparisons, and analysis of the Windows texture compiler. Python tools send images, change pages and brightness, update display tags, and inspect the protocol.

## Requirements & limits

- **Prerequisites:** A Positivo Vision R15M with its minitela package is required.
- **Prerequisites:** Image building requires ffmpeg and Wine; other controls are native Python.
- **Limits:** Writing an ACF that the firmware cannot render can freeze the display until recovery.
- **License:** MIT license.
