How can I send float number(such 3.14 or2.36..etc.) to serial port? can I define variable as float and send such as.. float dat void main() dat = 3.14; SBUF =dat; ...
floats are a 4-byte data object. If the receiver expects binary, send each of the float's 4 bytes. Otherwise, if the receiver expects ASCII characters (i.e., text), convert the float to a string (maybe using sprintf) and send all the characters in the string.
