Compiler/MSP430FR2433: Issue with sprintf with unsigned int

maanideep kumar

Part Number: MSP430FR2433

Tool/software: TI C/C++ Compiler

Hi,

I'm tryng to print unsigned integer through uart on teraterm. so, i specified my format specifier as %u. the compiler is not accepting it. So, can anyone have any idea to print my unsigned integer ?

sprintf(debug_string, "Distance: %u", result);

My IDE is CCS with V8 version.

Thankyou,

First suggestion would be "--printf_support=nofloat". In CCS 7.4, this is in "Build settings->Build->Compiler->Advanced Options->Language Options" (down at the bottom). This will make your program bigger, but it fit on an FR2433 last time I tried it.

Hello Maanideep,

Have you derived your code from a TI example?
If yes, which one.
What is your compiler version?
Do use use CCS v8.0 or 8.1?

Please show a compiler output.

Compiler output gives:
#2631 Conversion u not allowed in printf_support=minimal mode
You just cannot do it in the minimal mode.
