Hello, I am a beginner with the MSP430, and I am wondering if it is possible to print debugging messages using printf or a similar function while running your code on the MSP430. I see posts with people doing this with the LCD, but shouldn't it be possible to send debugging messages through your computers parrallel port and have them either captured into a text file or displayed in C- Spy? The device I am developing interfaces with several peripherals so I would be much happier actually using the msp430 to test the code and debug than setting up the IAR Emulation tools, etc. I would really appreciate any help/advice people had with this sort of debugging. Thanks Bob achillea88@achi...

Yes, if you have a C compiler, define putchar() to send a character out the
UART. Now printf will output to the UART. Hook the serial port up to the
PC, and you can watch it in hyperterminal etc..

Good question, but what if both uarts are already used, is there an
other way to do this?
thanks,
Martijn

Before Paul replies to this ;-) If you use Crossworks then you can get debug messages output over the JTAG interface to a console window in the debugger. This is relatively slow and can have an effect upon the operating speed of the processor (it pauses while the JTAG interface is being accessed) but when all other output interfaces are used up it can get you out of a hole.

Glad you responded to this, Ian. However, the next version of CrossWorks will not have this intrusive effect on the code, and you'll *still* be able to output debugging information over JTAG. Note that you can do a lot more than just output strings over JTAG using debug_printf(), the v1.1 software can use the JTAG interface as a virtual terminal, you can open files, and so on. Also note that debug_printf()'s implementation does *not* drag in the printf library--quite amazing, it's about 40 words of code to support debug_printf. Now, that's going to be invaluable to somebody debugging a system on its code limit... ;-) -- Paul.
