Based on Nuvoton N9H30 Coffee Machine Color Screen Solution

Coffee is categorized into Americano, drip, black coffee and espresso, etc. Various specialties are suitable for different people. A cup of coffee with fragrant milk cap can not only relieve the fatigue of work, but also get the taste of bitter and sweet. In the fast-paced environment of office workers, a good coffee maker is essential. A coffee maker is simple and quick to operate, eliminating the hassle and time involved in hand-ground coffee, while allowing you to enjoy the flavor of coffee with ease.

This solution is based on the Nuvoton coffee maker one-stop solution, using N9H30 to design the color GUI interface, M451 to design the main control board, and MS51 to design the refrigeration module. This solution focuses on Nuvoton's HMI color screen solution technology, currently Nuvoton has a wealth of HMI solutions, from the simplest Seg LED, to TFT-LCD and other color screen sizes, of which the newly launched MA35D1 product maximum support for 1920 * 1080 resolution.

At present, Nuvoton and SEGGER emwin deep cooperation, to provide free License, customers if the use of Nuvoton HMI products designed for color screen, you can use the emwin graphics library free of charge, and Nuvoton also provides various types of emwin sample code demo learning reference. Of course, out of emwin, Nuvoton HMI products also support LVGL and QT, which is convenient for customers to choose their preferred GUI operation.
