Board: MSB IoT

Overview

The MSB-IoT was developed at FU Berlin and is based on a STM32F415RG MCU. For a quick getting started guide you can stick to the steps explained on this page. Just make sure to use "msbiot" as the respective board name.

RIOT pin mapping

Please refer to this document for the RIOTs pin mapping for the MSB-IoT (Please note that the document only lists ports where a PIN is mapped). The pin mapping is chosen completely arbitrary and can be altered by editing the boards/msbiot/include/periph_conf.h header file.

User Interface

3 Buttons:

NAME	User Button T1	User Button T2	T RESET
Pin	PB13	PA0	NRST

3 user controllable LEDs:

| NAME | LED_RED | LED_YELLOW | LED_GREEN | | ----- | ----- | ----- | ----- | ----- | ----- | ----- | ----- | ----- | | Color | red | yellow | green | | Pin | PB8 | PB14 | PB15 |

There is also a yellow charge LED on the board indicating the charging process of the battery.

Supported Toolchains

For using the MSB-IoT we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.

Using UART

Step 1: Connect your usb tty to RX<=>PA02, TX<=>PA03 and GND<=>GND

Step 2: Done. The MCUs USART2 is used as STDIO.
