Using Spy-Bi-Wire with the MSP430 Launchpad

[Suraj] has been working with some larger MSP430 chips with won’t fit on the Launchpad board. But that’s okay because he built a shield and wrote a guide about using the Spy-Bi-Wire protocol for programming the chips.

SBW is a four-wire interface. In the past we’ve used all of the board’s programming connections for in circuit programming, but the chips that support SBW only need a connection to the SBW and TEST pins (of course the other two connections are for voltage and ground). This shield brings the four pins together into one male pin header. In the image above [Suraj] is using the technique to program an MSP430F4152. His guide is Windows-based, but looking back, [Sprite_TM] shows how to use SBW when debugging in Eclipse.

  1. Suraj must own stock in a solder company!

    Good demo of how useful/cheap the SBW interface is though (for chips in the portfolio that support it).

    1. Yeah, actually you can use the launch pad header connections directly. i used the board on top to prevent any confusion.becomes easier to connect . and yeah, i hate using wires. so i use the solder lead directly.

    2. and as he mentioned that you need to use the extra resistor and sometimes the capacitor on reset gets a problem. using the jumper pins on side(like in the post)gets over this problem.

  2. It’s OK.
    But what about the connector J4? It is located on the right edge of the Launchpad, near to J3.

    Did you read the User Manual to Launchpad?
    Yeh-h… young people, young people…
