printf() to IAR IDE

In the Debugger screen, you can click <View> => Terminal I/O to show that window.

This is assuming that you are using the "factory setting" for the Linker with the I/O emulation check box. All this is done with mirrors and smocks.in the PC. You do not even need a MSP430 to do this.

I do not have the View --> Terminal I/O option.

I think it is due to the fact that the kickstart version does not support this?

Hi newbie,

the two code lines above will do a simple thing: NOTHING!

In order to help you in getting started you need to provide some more info (i.e. which tool(s) are you using, which MCu do you intend debugging, ..).

Pls note that the library printf() will not work with devices with low RAM! You need to write your own in this case.

KickStart does support I/O emulation and even MSP430F2001 has sufficient RAM (126B) and Flash (1KB) to do it.

Are you?

MSP430F2112:

This message is now displayed when I enter a printf():

Fatal Error[e89]: Too much object code produced (more than 0x1000 bytes) for this package
Error while running Linker

The normal DLIB library is huge. You need to use the "Tiny" or "small" option. Alternatively, you could use CLIB with either "medium" or "small" option.

Yes, tried changing to CLIB small but no success.

The device is MSP430F2272.

I removed some code and now it works.

I suspect the Kickstart has a code size limit that was reached?

Thanks.

The code size limit is 2KB for MSP430 or 4KB for MSP430X. printf, scanf, and floating point calculations take a lot of code and are very slow too.
