Printing Float on LCD PSOC 4.2 and ARM GCC 5.4 COMPİLER

[Anonymous]

Hi everone!

I have same problem as a lot of body but every solves are for old program (such as ARM GCC 4.7)

float ex1 = 1.232;

int ex2= 123;

char exchar[30];

sprintf(exchar,"Testing: %f",ex1);

this printing on LCD Testing:

but

sprintf(exchar,"Testing: %d",ex2);

this printing on LCD  Testing: 123

How can I fix this

Please check this KBA:

Floating-Point Support for PRINTF and SCANF in GNU Arm Compiler - KBA89724

Make sure that the heap size required to support sprintf and sscanf is set in your project (.cydwr > System > Heap Size). The default value is 0x80, which will not be enough to support these functions. You can change it to a higher value such as 0x1000.
