Tip

When using this board with RIOT, set the BOARD variable to nz32-sc151 in your Makefile. If you follow the standard RIOT project structure, your Makefile should look like this:

./Makefile

# name of your application
APPLICATION = hello-world

# Change this to your board if you want to build for a different board
BOARD ?= nz32-sc151

# This has to be the absolute path to the RIOT base directory:
RIOTBASE ?= $(CURDIR)/RIOT

include $(RIOTBASE)/Makefile.include

Support for the Modtronix nz32-sc151 board.

This board provider is modtronix. They don’t supply data sheet’s but there wiki can be found HERE. The schematic for there board can be found HERE.

Using UART

This board doesn’t open an UART or serial interface threw the USB automatically, and the USB device driver hasn’t been implemented to RIOT yet. Therefore, to open an UART interface one hast to connect a usb/ttl converter to the UART3 pins PB11 (RX3) and PB10 (TX3).

Flashing the device

The standard method for flashing RIOT to the nz32-sc151 is using dfu. On linux you must get dfu-util package v.8.0 or newer. You can try:

sudo apt-get install dfu-util

but most repos install older versions, therefore you should clone from dfu- util and follow building instructions HERE.

Once dfu-util is installed you can just flash as a normal board, although sudo privileges are required.

sudo make BOARD=nz32-sc151 flash

NOTE: this only works for linux, for windows you can use ST Microelectronics DFU Bootloader although you will need to build the files independently.
