MSP430 C Compiler V 4.4.2 won't printf unsigned longs

Edward Averill

What the subject says. I'm having zero luck, and poking around to try to get the project to let me choose library support has been fruitless.

Anyone have any insight into this? All help appreciated!

Under CCS Project Properties -> Build -> MSP430 Compiler -> Advanced Options -> Library Function Assumption what is "Level of printf/scanf support required (--printf_support)" set to?

Based upon upon the tool-tip for this option, to get the support for the "long" width flag for integers you need to select either the "full" or "nofloat" option.

Please see if this wiki page about possible printf issues is helpful.

Thanks and regards,
