@seb Sure. I'll share it here. Like I said it is very quick and dirty. It accepts an OSC message with only one variable (integer or float) of the form:
'/adress1, if, value'
integer (i) should also work.
I do not parse the address tag(s). Also, in a normal OSC message multiple type tags can be used in one message, like: '/adress1, if, intval, floatval'
That is not implemented.

def readFloat(data):
if(len(data)<4):
print("Error: too few bytes for float", data, len(data))
rest = data
float = 0
else:
float = struct.unpack(">f", data[0:4])[0]
rest = data[4:]
return float
def readInt(data):
if(len(data)<4):
print("Error: too few bytes for int", data, len(data))
rest = data
integer = 0
else:
integer = struct.unpack(">i", data[0:4])[0]
rest = data[4:]
return integer
