TIDA-00120: PMP7605 GUI PC S/W cannot set serial port to be connected ?

Yongsung,

It looks like you were able to successfully compile and download the source code to the board since you are generating PWMs.

By default, the GUI is not enabled in the source code. Have you recompiled it and flashed the MCU after uncommenting the "//#define GUI" at the beginning of each source file?

You can find some additional clarification here: https://e2e.ti.com/support/microcontrollers/msp430/f/166/p/346502/1484353#1484353 

The PMP7605 GUI was also not tested for Windows 10 compatibility. You might try running it in compatibility mode, or as administrator. I will continue to look into your issue and reply if I find anything else.

Hi Bart,

Thanks for your advice!

Since I was quite sleepy in the midnight, my question was somewhat unclear.

Of course, I ereaed remark symbol "//" in fromt of "#define GUI" in main .c , GUI.c and Config.c. Compiling and target downloading was no roblem. The PWM signal was made by using Config.c parameter by adding comment symbol "// #define GUI" at any c files.

By setting a breakpoint at Interrupt_enable(RX) in GUI.c, I found that S/W is jumping to GUI.c well. But when I set breakpoint on interupt vector subroutine, it was hanging all the time. Of course no signal on LED2/3 and R/TX port when I run GUI PC S/W and clicking connection retry button. It was monitored by scope.
MPPT target board MSP430F5132 itself have no problem for UART comm.

So, as I said GUI PC S/W do not send any initialization signal to any UART port. I tried to find any external config file that can change com port assignment . But there was no. And PMP7605 GUI PC SW do not send any UART signal to anywhere outside. And no menu to set com port.

My PC is showing that MSP Application UART1 is assigned to (COM7).
Is there no way that I can config 'PMP7605 PC SW' to contact with COM7 port ? Any hyper termial S/W can set any COM port. And verified that MSP-EXP430 UART was responding on the Hyper terminal S/W. I think PMP7605 PC app designer can fix this issue.
Expecting any method !

YS,

Thank you for the detailed response and explanation, it helps tremendously. 

Regrettably, I don't have a solution based on what you said. It does indeed look like the GUI software isn't sending anything out of the COM port.

I'm working on getting the original source code for the GUI application so I can look deeper into how it operates and get you a solution. I'll update you on the progress soon.

Bart

YS,
I believe I have tracked down the issue for you.

The software was intended to be used with the G2 Launchpad as the interface board, but you are using the F5529 Launchpad. The G2 only enumerated a single COM port, as opposed to the two that the 5529 enumerates in hardware. The GUI (via the listcomports.exe application) is detecting the debug interface COM port first and attempting to use it, rather than the application COM port. This listing is based on the USB VID/PID rather than the port number, so the debug port will always be selected.

I do need your help to test this if possible. Can you uninstall the debug com port in your device manager, leaving the application port enabled, and attempt to connect again? listcomports.exe should only see the single entry from the Launchpad and connect approperiatly. If this works, please let me know and I will attempt to get you a new version of the GUI that will be a bit more robust to this issue.

Hi Bart,

 Since I do have serveral pcs of  G2 and F5529 launchpads.   I tested both.    In case of G2,   it was never been connected.  

In case of F5529 Launchpads,   As you guided, I removed the  debug com port driver in PC device manager.    But the GUI S/W  was not connected F5529 launchpad serial port.    But when I tried to start the PC GUI SW more than 10 times,   it was connected with target board suddenly.  (It's the case when I didn't  remove the debug com port driver in PC device manager).          

For overall,  GUI S/W can be connected with 5529 Lauchpad.   But connection can be done  once per 10-20 times of  GUI S/W restart trial.     If possible,   need to make some modification of GUI S/W to set com port to be connected ratehr than USB VID/PID.    

Like any other Hyper terminal S/W (Coolterm & etc).     I attached the UART waveform picture when it wsa connected.  

yellow= EVM RX,  red= EVM TX pin.     Every 1sec,  PC GUI S/W send UART link stay & update signal.

In my thinking ,   adding new menu to set com port will be difficulut.   How about the GUI S/W to be linked with  external

com??.ini file to set the com port among  the com port that PC  dvice manager assigned for the dedicated H/W ?      

Thank you !

YS,

Thanks for the follow-up, this information is very helpful.

I'll work on the changes to the software you propose and get it updated as quick as possible.

Bart
