SiM3U1xx 32-bit MCU USB Development Kit

Overview

This is a development kit [3] that is used to develop software for the SiM3U1xx MCUs.

For more information about the SiM3U167 SoC and the SiM3U1xx board, refer to these documents:

The board configuration supports the following hardware features:

Interface	Controller	Driver/Component
NVIC	on-chip	nested vector interrupt controller
SYSTICK	on-chip	systick
AES	on-chip	crypto
DMA	on-chip	dma
FLASH	on-chip	flash memory
GPIO	on-chip	gpio
UART	on-chip	serial port-polling; serial port-interrupt

Pin	Name	Note
PB1.12	TX (O)	Serial connection to host via USB virtual COM port
PB1.13	RX (I)
PB1.14	RTS (O)
PB1.15	CTS (I)
PB2.8	Push button switch (SW2)
PB2.9	Push button switch (SW3)
PB2.10	Red LED (DS3)
PB2.11	Yellow LED (DS4)
PB1.5	Potentiometer
PB2.12	Potentiometer bias

The sample application Hello World is used for this example. Build the Zephyr kernel and application:

# From the root of the zephyr repository
west build -b sim3u1xx_dk samples/hello_world

Connect the sim3u1xx_dk to your host computer using both USB port and you should see a USB serial connection.

Open a serial terminal (minicom, putty, etc.) with the following settings:

Reset the board and you’ll see the following message on the corresponding serial port terminal session:

Hello World! sim3u1xx_dk/sim3u167
