Sorry to dig this thread back up after been dead for do long as I was searching how to send a float over I2C.
I've got the code working posted by Nick in post for just sending 2 example values of 6.75 (fnum) & 29.31(foo) and I would like to add another slave to send example values of 13.32(fnum) & 3.25(foo).
I know I would have to alter the MY_ADDRESS say to 43 but the part I'm not sure of is how to get the master to read more than one slave unit.
Is this possible ??
if so how could I do it
