Compiler/MSP430F5659: Converting floating point numbers to strings for TI grlib drawstring functions

Jerry Bucci

Part Number: MSP430F5659

Tool/software: TI C/C++ Compiler

Hi,

I have a bunch of sensors attached to the A/D inputs of the MSP430. After converting the data into floating point variables, I need to convert the value into a string for the grlib DrawString functions. My question is should I write my own routines to do this, or are there some built in functions such as PRINTF that I can use parts of to accomplish this?

Thanks,

If you enable the full-printf functionality, sprintf () should work.

Great Thanks Keith!!- It worked when I changed minimal to full.

char result[10];
float testf=44.61;
sprintf(result, "%f",testf);

Graphics_drawStringCentered(&g_sContext,&result, 5,...
