Does Anybody have labview drivers to program an MSP430 via SERIAL PORT?

Hello eyal,

I don't know of a specific driver, although you will find some third party libraries out there if you do a google search.  The alternative is to use LabVIEW Embedded.  The following discussion forum talks about this same question:

Is it possible toDownload code on microcontroller through JTAG using Labview?

Hope this helps,

I may be wrong here, but it doesn't sound like he is trying to develop the firmware with labview, he is just trying to program the microcontroller using Labview, maybe just deploying a .hex file?

I have done that with SI Labs processors and their USB JTAG programmers, but have really only had luck in using their dlls or command-line programmers that I called using Labview.

Very old post - but I have a complete implementation of MSP430 bootstrap loader (BSL) in LabVIEW.  Doesn't use any Windows DLLs - pure-G/VISA.  The target needs to have its BSL TX/RX pins, plus TCK and *RST, accessible.  A serial adapter/level converter that maps DTR and RTS to *RST and TCK is needed.

Hi David,

I'm interested in learning more about your MSP BSL implementation. Do you have an app note or anything like that to review?

Thanks... Scott Hurst

Scott,

I don't have an app note related to my own code, but you can check TI's website for appnote SLAA089C.pdf.  It was the guiding doc I used that describes the BSL architecture and protocol.  I think there's a rev D release recently which adds support for extended-memory devices.

My VIs map pretty much one-to-one with the functions available through BSL, like erase, unlock, read, write, etc.  It's all done as plain-vanilla serial using VISA, no DLLs, so it should port well across platforms and LV versions.  BSL is a masked-ROM feature of all MSP430s that's entered via a pin toggle between the MSP430 *RST and TCK pins.  After that, it's just Tx/Rx on a pair of port pins (unfortunately not the normal UART pins).  Hence the need for a level converter between RS-232 levels and the device.  Contact me via email or provide me your email address to discuss the details.

Hi Dave,

Thanks for pointing me to the TI app note. It's now up to rev D.

I'm building a test system for one of our products which uses an NI DAQ card and some custom circuity for the interface hardware and Labview from the front end. I wasn't planning to use RS232. I have DIO available and the signals you indicate that are necessary to implement the BSL interface are there (with some additional mods to my external circuit). Anything you can do to steer me in the right direction would be appreciated.

Scott,

My full reply is via private email, but for anyone else's benefit who is following this thread, I wouldn't recommend using DAQ DIO for MSP430 BSL.  It's really implemented as an asynch serial interface.  Any comm port will do.

Hi David,

          I am working on TI MSP 430.I couldnt get drivers needed to run in the labview DAQ.Could you help me how to interface the serial port using G/VISA.My email address is:shravan400@yahoo.com.

Hope you get in touch with me.

Thanks

Wouldn't it be easier to implement using the parallel port instead of the serial port?
