Flash 55 KiB
Frequency up to 8 MHz
FPU no
Timers 2 (2x 16bit)
ADCs 1x 8 channel 12-bit

While programming, the minimum supply voltage is 2.7 V instead of 1.8 V.
When the supply voltage supervisor (SVS) (a.k.a. brownout detection) is used, the supply voltage must initially be at least 2.0 V due to the hysteresis of the SVS circuitry. Afterwards the MCU remains operational with VCC >= 1.8 V.

Pinout of the Battery Holder Board

The pins above the JTAG header with the pin closest to the power supply switch being denoted as Pin 1, the signals are as follows:

Pin 1 2 3 4 5 6

The battery holder board contains a 3V power regular that powers the MSB-430 board via 3V pin (pin 1 on JP2). The switch at the bottom can be used to select the input voltage of that power regulator: If the switch is in the position towards the daughter board, it will use the 5V pin of the header above the JTAG header as power supply, otherwise the batteries are used as power supply.

Flashing RIOT

Place the MSB-430 board into the batter holder board with the SD card socket facing towards the battery holder board and the (likely unpopulated) antenna connector facing away from the switch and JTAG-connector of the battery holder board. (As shown in the picture at the top of the page.)

Afterwards, connect a JTAG debugger supported by mspdebug; by default the Olimex MSP430-JTAG-Tiny is assumed, which is among the less expensive options.

If you are not using the Olimex MSP430-JTAG-Tiny (or a compatible programmer), set MSPDEBUG_PROGRAMMER to the correct value via an environment variable or as parameter to make. E.g. use make BOARD=msb-430 MSPDEBUG_PROGRAMMER=bus-pirate to flash using the bus pirate.
It is recommended to use the external power supply via the 5V pin instead of the battery while flashing.

Once the board is firmly connected in the battery holder and the JTAG cable is connected, just run

make BOARD=msb-430 flash

in the application's directory.

Using the shell

stdio is available via the UART interface with RXD = P3.7 (pin 35 on the header) and TXD = P3.6 (pin 34 on the header) at 115,200 Baud.

The easiest way is to connect an USB TTL adapter (such as the cheap cp210x or ch341 based adapters) to the battery holder board as follows:

TTL adapter MSB-430 Battery Holder Board
----------- ----------------------------
GND --- 1 (GND)
TXD --- 4 (RXD / P3.7)
RXD --- 5 (TXD / P3.6)
5V --- 3 (5V)
