Need help with LaunchPad Tempurature Demo GUI

Richard Lyons
Prodigy 30 points

Hi,

    I hope someone here can help me.   I tried executing the MSP430's LaunchPad Tempuature Demo GUI software but I can't get it to work.  After launching the GUI software (LaunchPad_Temp_GUI.exe) I get a black screen with the words:

    "Please, select the COM port that your LaunchPad is connected to."

                                                    [0] COM1

                                                    [1] COM2

                                                    [2] COM8

 

I want to select '[2] COM8' but the GUI software seems 'hung up' because there's no way to make a 'selection'.  No keyboard key strokes do anything, moving the mouse arrow does nothing.  Does anyone know what could be my problem.  (I'm using a PC running Windows XP op system.)

Thanks for your help,

[-Rick-]

    Unfortunately, OCM port enumeration is a tricky field in Windows. There are several different and independent mechanisms. As a result of this, sometimes applications are unable to accept any COM port >7 or those with a gap in the numbering before them.

    You can try to manually change the COM port number (in the device manager) from 8 to 3. Maybe it helps. It depends on many things, including which driver the first two use and whether they are real COM ports or attached via USB etc. It's a long and sad story.

    Hello Jens-Michael Gross,

       Thanks for your advice.  I'll experiment with trying to change COM port numbers.

    Richard,

    this is one of the things that we will improve in our GUI as well as documentation. But specifically, press the number that indicates your com port, for example if you want to select COM8, press 2. If the list goes higher than 10, press 2 digit keys to select the 2-digit number. Then press Enter to finalize your selection. Then the GUI should connect to your desired COM port.

    Hope that helps!

    Hello Dung,

       my my, I'm happy to read your reply.  Thank you.

    I will follow your instructions.  I was working on an 'Blinking LED' program, based on a YouTube video, to help myself learn about the MSP430.  That video starts with a program that contains the following characters:

       //  D. Dang
       //  Texas Instruments, Inc
       //  October 2010
       //  Built with CCS Version 4.2.0 and IAR Embedded Workbench Version: 5.10

    Ha ha, I'm guessing that you are the above  'D. Dang'.  Again, thanks for you help.

    I want to connect a microphone to the LaunchPad and figure out how to program the MSP430 LaunchPad to detect audio pulses whose frequencies are in the range of 4-5 kilohertz.  I have some knowledge of digital signal processing (DSP) but I'm sure struggling with how to use the MSP430 to perform the DSP that I desire.

    Thanks again, & Regards,

    [-Rick-]

    Hi,

    I have read the Post by Dung Dang replied on 05-26-2011 5:25 PM but it failed solve my problem. I am trying to use launchpad temp gui. clicking on the execute file brings up a screen that says

    "Please select the COM port that your launchpad is connected to". It offers " [0] COM1  and [1] COM3  .  My msp430 is connected to com port 3. I press 1 and then enter but nothing happens.

    There is no recognition of the key presses of anything else. I am running windows 7. That is all I have done. I attached msp430 board by usb to my computer and then tried to access the gui. is

    there something else I should do.

    Yo did press [1][enter]? Just to confirm you didn't forget the [enter]. Just by pressing a number, nothing will happen.
