but ASCII is just bytes, so subtracting 48 should do the ASCII to float job, right?
How are you sending values from Arduino to Pd? Do you use Serial.write or Serial.println? use [print] before you send stuff to [unpack] to see what you get. A type mismatch is when you expect a float but you get a symbol, for example.

hello


i am working with arduino and raspi with comport spiiting out values from pots attached to the arduino board and i keep getting the endless warnings of 

error: unpack type mismatch

error: unpack type mismatch

error: unpack type mismatch​


is there a way to remedy this? i looked around and i heard some people talking about "atof" which i assume is ascii to float.

But i cannot find it anywhere. I thought it was in zexy but maybe i have the wrong name or perhaps i am off the mark entirely
