Schematics

Pinout

The 64 pins on the edges of the PCB are connected to the corresponding MCU pins. Hence, the following pinout of the naked MSP430-F1611 MCU chip matches the pinout of the header board:

Flashing RIOT

Connect the board to a JTAG debugger supported by mspdebug; by default the Olimex MSP430-JTAG-Tiny (as shown in the picture above) is assumed, which is among the less expensive options.

@note 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=olimex-msp430-h1611 MSPDEBUG_PROGRAMMER=bus-pirate to flash using the bus pirate.

@warning You can power the board via the JTAG programmer by placing a jumper at P_IN. However, the JTAG programmer will only be able to provide a limited current. You may want to disconnect the header board from devices consuming a lot of power prior to flashing.

@warning If the board is powered externally, make sure to place the jumper in P_OUT position, not in P_IN position.

@warning A jumper in P_OUT is mutually exclusive to a jumper in P_IN. Never connect both at the same time.

@note Pin 1 on the JTAG connector has a small white triangle next to it and square pad, compared to the round pad used by all other JTAG pins.

Once the jumper is correctly placed in either P_IN or in P_OUT and the JTAG cable is connected just run

make BOARD=olimex-msp430-h1611 flash

Using the shell

stdio is available via the UART interface with TXD = P3.6 (pin 35 on the header) and RXD = P3.7 (pin 34 on the header) at 9,600 Baud.

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

TTL adapter    Olimex MSP430-H1611
-----------    -------------------

       GND --- 63 (DV_SS)
       TXD --- 35 (P3.7)
       RXD --- 34 (P3.6)
