NUMAKER M3334KI

Overview

The NuMaker M3334KI is a microcontroller platform with comprehensive peripheral integration specially developed by Nuvoton. The NuMaker-M3334KI is based on the NuMicro® M3331 series MCU with ARM® -Cortex®-M33 core.

Features:

  • 32-bit Arm Cortex®-M33 M3334KIGAE MCU

  • Core clock up to 180 MHz

  • 512 KB embedded Dual Bank Flash and 320 KB SRAM

  • USB 2.0 Full-Speed OTG / Device

  • USB 1.1 Host

  • Arduino UNO compatible interface

  • One push-button is for reset

  • Two LEDs: one is for power indication and the other is for user-defined

  • On-board NU-Link2 ICE debugger/programmer with SWD connector

More information about the board can be found at the NuMaker M3334KI User Manual [1].

Building and Flashing

The numaker_m3334ki board supports the runners and associated west commands listed below.

flash debug

Flashing

Here is an example for the Hello World application.

On board debugger Nu-link2 can emulate UART0 as a virtual COM port over usb, To enable this, set ISW1 DIP switch 1-3 (TXD RXD VOM) to ON. Connect the NuMaker-M3334KI to your host computer using the USB port, then run a serial host program to connect with your board. For example:

$ minicom -D /dev/ttyACM0

# From the root of the zephyr repository
west build -b numaker_m3334ki samples/hello_world
west flash

Debugging

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b numaker_m3334ki samples/hello_world
west debug

Step through the application in your debugger.

VS Code Support

Here is to go through VS Code instead of command line.
