Hi,

I have a strange problem. If I write code like this:

#include ''stm32f10x.h''

float

test;

int

main(

void

) {

while

(1) {

test=test+0.01;

}

}

and display variable test in STM Studio I see that this var go to value about 2,500 and after that sets to 0 and again in loop. If I write that code:

#include ''stm32f10x.h''

int

test = 0;

int

main(

void

) { test = 0;

while

(1) {

}

}

and try change a var by STM Studio to for example 2, I see the value 2 about 0,5s, after that it sets to 0. It is strange for me and I dont understand it. Where is the problem? I use CooCox.
