Hi, My question is similar to this devzone.nordicsemi.com/.../ but I can't get it to work.
I am using SEGGER_RTT_WriteString and sprintf for debugging, but I am not able to print a float value such as 3.1415. I use the folowing code for printing intergers and it works fine:
uint8_t int_value;
int_value = 129;
char int_str[80];
sprintf(int_str, "Integer value is %d\n", int_value);
SEGGER_RTT_WriteString(0, int_str);
I am then trying to print a float value in the same way, but I have had no success so far. I have tried with "%f", "%0.2f"etc, but the printing result is just nothing or 0.
float float_value;
float_value = 3.1415;
char float_str[80];
sprintf(float_str, "Float value is %f\n", float_value);
SEGGER_RTT_WriteString(0, float_str);
Any suggestions are very much appreciated. Thanks!
