Using LCD on the MSP-EXP430.

Other Parts Discussed in Thread: CCSTUDIO

I want to use my experimenter board's LCD for displaying general messages so I copied the "hal_lcd.h" and "hal_lcd.c" into my project and included it in my include file. I copied a test line from one of the source files in user exp demo. When i build it and debug it there is no error shown but while running the program the following line is displayed.

Can't find a source file at "/tmp/TI_MKLIB28qeec/SRC/copy_zero_init.c"
Locate the file or edit the source lookup path to include its location.

Is the procedure correct?

Thank you.

The problem may be that the WDT fires during C startup code

I tried doing this but in ccstudio version 5.4 there is no such option available.

Please help.

The available linker options shown by CCS depend upon which the compiler version selected in the project (on the General page of the project properties).

To disable the watchdog during the C start-up code you need to either:

1) Change to use MSP430 compiler version 4.2.0 or later, and then set the linker --cinit_hold_wdt option to on. See http://processors.wiki.ti.com/index.php/Compiler_Updates and http://processors.wiki.ti.com/index.php/Compiler_Installation_and_Selection for information on updating the compiler version.

2) Add a _system_pre_init function to your project as described on http://processors.wiki.ti.com/index.php/MSP430_FAQ#WDT_fires_during_C_startup_code
