can i use the launchpad pins test and rst to program other msp430 series?? for example the msp430f2??

thanks!!

I have not tested this one, but my understanding is that there are two different Intefaces that allow to program any MSP430 device - this is either the MSP430 JTAG interface or the Spy-Bi Wire interface (which is basically a serial JTAG commuincation). My assumption is that any MSP430 uses the same Spy-Bi Wire interface. So I assume that the launchpad programmer/debugger should also cover the communication with other MSP430 devices....

In an attempt to provide some clarity on this subject, which appears to come up quite often given the number of posts about it, there are 2 fundamental things to understand:

What emulation interface is supported by the hardware platform, in this case the Launchpad?
What emulation interface is supported by a particular MSP430 device.

For #1, what emulation interface is supported by the hardware platform, you can consult the documentation associated with the Launchpad itself, or the following MSP430 Hardware Tools Guide.
The answer is the Launchpad only supports the Spy-Bi-Wire (2-wire JTAG) interface.

For #2, what emulation interface is supported by a particular MSP430 device, you should consult the datasheet of that device which is found on the Product Folder for that device on www.ti.com. Another possible resource is the aforementioned MSP430 Hardware Tools Guide.

thank you both for your reply, so for example if the

msp430f2618 is able to be program by spy-bi-wire it means

that i can burn the program with the launchpad.

The MSP430F2618 does not support the Spy-Bi-Wire protocol, therefore can not be programmed by the Launchpad. You will need to use something like the MSP-FET430UIF JTAG emulation pod.

I'm interested in using the LaunchPad in order to program the CC430 chip. I'm wondering how I would interface the chip to the LaunchPad.

I'm relatively new to home electronics development, so the more details, the better.

Thanks,
Ryan

Ryan and oscar,

What information are you looking for that has not been provided in a previous post? If you could provide additional detail, it would be helpful. Otherwise I'm guessing.

I gather from both of your posts that what I have supplied above is still insufficient in answering your questions.

From what I've read, both the LaunchPad and the CC430 support SBW. I'm wondering how I physically connect the two in order to program the CC430. I know the LaunchPad has the sockets for DIP chips, but the CC430 is a surface mount chip.

If you are designing your own target hardware with a specific CC430 device, then you will need to route the Spy-Bi-Wire traces and any other specific connections required to test points or ideally a header which can be connected to the Launchpad emulation logic.

The information about the necessary signals is provided in the MSP430(tm) Hardware Tools User's Guide (Rev. F) in Chapter 2. You can also consult the schematics of the Launchpad to see the appropriate signals as well.

yes, i read the same about some msp430f5 series, so i can use the pins of my launchpad and program this devices??

it is the microcontroler's diagram look the circle, it can be program by spy bi wire !!

Generically, I say yes. But I suggest you search for the term "Spy" in the specific device datasheet to get your answer.

The reason I am not saying categorically "yes" is that you are not providing a specific device part number, but referencing a device series, ie. MSP430F5xxx.
I want to be careful to not mislead you by saying yes and then you finding a device in that series that happens to not have it.

This is why I suggest you refer to the device datasheet and existing documentation to get your answer.
