URGENT : please help-MSPEXP430G2 Launchpad

salony agarwal

I have got a MSP-EXP430G2-LaunchPad demo. and following the instruction of "Getting Started with the MSP430 LunchPad" to step 10. every thing looks cool to me. However, when I went to step 11, that I clicked "Build" button and watch the tools run in Console window. There are a lot error messages (in Red) as follows, I prety sure that I have not done anything wrong and changed any C program codes. I just pasted the Code from .txt to main.c and save it. Why have I had the following error messages, and how to fix them? Thanks

Hi Salony,

DId you import the example? If so did you select "copy files into workspace" or not? Which exact document where you following? Is it something from the workshop posted on the wiki?

Best Regards,
Lisa

hi Lisa

thanks for your reply.Actually the header file was wrong..

now it is working. I am not comfortable with C programming on MSP430.I need to interface an IR(infrared )

sensor.and I am unaware of the syntax like( P1OUT,BSCCTL3..etc )..so from where can i get information about these keywords..??

thanks

Hi Salony,

one of the best places for information on msps is usually the family user guide. This should be the link for the G2231 and family.

Glad to hear you found the issue.

Lisa

Dear Lisa,

I am facing now with this problem, but I couldnt sort out where the problem pops from. I am working on EXP5438A board. I have created my own project with a simple sample code which actually works fine. I wanted to display the results on the LCD and so I have loaded necessary files from the user experience demo into my project. Result is this error.

Severity and Description Path Resource Location Creation Time Id
errors encountered during linking; "tryit.out" not built tryit line 0 1339297523953 455
unresolved symbol fonts_lookup, first referenced in ./main.obj tryit line 0 1339297523953 454
unresolved symbol fonts, first referenced in ./main.obj tryit line 0 1339297523953 453
unresolved symbol GrayScale_fonts, first referenced in ./main.obj tryit line 0 1339297523953 452

This error comes when I add the following instruction halLcdPrintXY(&lcdstring,0,0,OVERWRITE_TEXT); and this instruction is available in hal_lcd.c. But I have included this in the header file as #include "hal_lcd.c"

I am thankful for any suggestions or help.

Best,

Vidya.

Hi Vidya,

CCS also needs to be able to find the header file. This is why you are seeing the errors. Have a look at this wiki topic, and fix and check your include options and paths.

Lisa
