You can not use the float as an address for your data and then send it over serial. It is expecting (a pointer to) a string, so you should provide one. You can just create a transmit buffer (ex. char txbuf [64]) and then use sprintf to format the float into a string and put it in the buffer. Then, you can send this formatted string using ...
WebThe function u82s() as written is not reentrant, because it uses a static string. Perhaps a better design would be to provide the string as an argument. That way, the function could format the number in any place of a longer string. (But then it should not write '\0' at the end). I don't agree with the previous comment that this function is slow.
