CHAPTER 2 | SETTING UP THE MSP430-P2618 BOARD

2.1 Introduction to the chapter

This section helps you set up the MSP430-P2618 development board for the first time. Please consider first the electrostatic warning to avoid damaging the board, then discover the

hardware and software required to operate the board. The procedure to power up the board is given, and a description of the default board behavior is

detailed.

2.2 Electrostatic warning

MSP430-P2618 is shipped in a protective anti-static package. The board must not be exposed to high electrostatic potentials. A grounding strap or similar protective device should be worn when handling the board. Avoid touching the component pins or any other metallic element.

2.3 Requirements

In order to set up the MSP430-P2618, the following items are required:

- A source of power – the board can be powered through JTAG connector; or through the external power jack connector.

- Debugger supporting 14 pin JTAG interface and the used microcontroller MSP430F2618.

All our MSP430 programmers are recommended for MSP430-P2618:

- Olimex MSP430-JTAG-TINY-V2 – small emulator/programmer ideal for beginners:

https://www.olimex.com/Products/MSP430/JTAG/MSP430-JTAG-TINY-V2/

- Olimex MSP430-JTAG-ISO-MK2 – our best MSP430 emulator/programmer (featuring display, SD card and 3 modes of operation):

https://www.olimex.com/Products/MSP430/JTAG/MSP430-JTAG-ISO-MK2/

- Olimex MSP430-JTAG-RF – the first wireless MSP430 emulator/programmer:

https://www.olimex.com/Products/MSP430/JTAG/MSP430-JTAG-RF/

Also, a host-based software toolchain is required in order to program/debug the MSP430-P2618 board. There are also a number of ready IDEs available like IAR Embedded Workbench, Rowley

CrossWorks, Code Composer Studio, etc.

Page 7 of 23

We also provide our own flash programming software which can be distributed free. You can find it at the above mentioned debuggers' web pages.

2.4 Powering the board

There are two options for powering the board:

Either set the jumpers P_IN closed, P_OUT open so you can power from JTAG connector

OR open P_IN, close P_OUT jumper and then use the power jack connecter to provide 5V DC.

Note: In previous revisions there was an option to provide 6.5V AC, which is no longer the case.

On powering the board the PWR LED, LED1 should turn on.

2.5 Prebuilt software

On powering the board the PWR LED should turn on. The LCD should show 3 lines of text and the ability to control the selector marker between them. On pressing the joystick over our test of choice it should be conducted.
