MSP-GANG: Setting programming speed - not using the GUI

Jacob Wyrick
Expert 8655 points

Part Number: MSP-GANG

Hi team,

We're trying to use MSP-GANG to program devices and can't seem to set the JTAG_SPEED correctly. 

We're using the provided c-file for the MSP-GANG, but unclear how we should set the JTAG_SPEED so that when we are using a standalone MSP-GANG to do programming that the speed gets set properly.

Is there any guidance you can provide?

Thanks,

Jacob

    Hi Jacob,

    Are you using the device in standalone mode or with the C file? If you are in true standalone mode (using the arrow keys and buttons on the MSP-GANG programmer), then my understanding is that the SBW/JTAG speed settings are stored in the generated .mspgangimage file loaded on the MSP-GANG.

    In C, the correct function call to set the JTAG speed from the DLL is MSPGANG_SetConfig (which appears to be aliased as pMSPGangSetConfig in the example). The index would be CFG_JTAG_SPEED and the data would be your interface speed setting as shown below from the MSP-GANG User's Guide. 

    Best Regards,
    Brandon Fisher
