NuMaker -M256SD

The NuMaker-M256SD is an evaluation board for Nuvoton NuMicro M254MD2AE, M254SD2AE, M256SD2AE and M256MD2AE microcontrollers with COM/SEG LCD driver and capacitive touch key sensing function. The NuMaker-M256SD consists of two parts: an M256SD target board and an on-board Nu-Link2-Me debugger and programmer. The NuMaker-M256SD is designed for project evaluation, prototype development and validation with power consumption monitoring function.

The M256SD target board is based on NuMicro M256SD2AE to evaluate the capacitive touch key sensing function on the touch key TK1 with messages displayed on a HTN-LCD panel for Human Machine Interface applications. For developing touch key system and fine tuning associated environment variables easily to adjust sensitivity of the touch key, Nuvoton provides NuTool – NuSenadj to set hardware and software parameters automatically. For the development flexibility, the M256SD target board provides the extension connectors, the Arduino UNO compatible headers and the capability of adopting multiple power supplies. Furthermore, the Nuvoton-designed ammeter connector can measure the power consumption instantly, which is essential for the prototype evaluation.

In addition, there is an attached on-board debugger and programmer “Nu-Link2-Me”. The Nu-Link2-Me supports on-chip debugging, online and offline ICP programming via SWD interface. The Nu-Link2-Me supports virtual COM (VCOM) port for printing debug messages on PC. Besides, the programming status could be shown on the built-in LEDs. Lastly, the Nu-Link2-Me could be detached from the evaluation board and become a stand-alone mass production programmer.
