// In the size optimized nano library used by ATMEL, floating point conversion

// could not manage to make it run (removing -specs=nano.specs in linker flags works though,
// but we propably should include this). Using floats with sscanf is also expensive.
// Furthermore, the stdio.c library by ATMEL can't resolve the %hhi specifiers
// Therefore, I adapted this function.
