BunMaker

BunMaker is a free GUI development IDE for BunHMI. You can design and download code via USB to BunHMI.

Using the BunMaker Editor software, you can develop HMI GUIs by dragging and dropping components (such as graphics, text, buttons, sliders, etc.) and utilizing the BunTalk protocol—a script-like, text-based protocol—to define how components interact with each other.

The BunHMI display connects to an MCU via TTL Serial (5V, TX, RX, GND). The BunTalk protocol can be used to notify the MCU or control GUI components. All instructions are in an ASCII text-based format, making it easy to learn without requiring additional libraries.

The BunHMI Display is based on LVGL and uses BunMaker for GUI design, providing an ideal solution for creating GUI applications.
