I need to convert uint16_t value to a string. I want the string to be a decimal respresentation of the number.

Example: uint16_t i=256 string: 256

I tried with itoa(i,string, 10) but when i value increases starts printing negative values.
I send the string via the Serial Port.(UART)
It is there some alternative?

Use sprintf with %u format for unsigned int:

uint16_t i = 33000;
sprintf(str, "%u", i);
