Always and again Thanks Melanie for the support.
Just one question about the "label" at the end of a I2CWRITE command
I see in the help menu this sentence "If the optional Label is included, this label will be jumped to if an acknowledge is not received from the I2C device. "
My question :
Could we say this is a GOTO or a GOSUB command ?

I was "swimming" when I was building a prototype WITHOUT the I2C module
(TV RECEIVER MODULE) connected ....
Program was working ... let say 6 times ... and seems to go in a strange loop
... I would say a "dead loop" .... I use a Blinking led to follow the process !

I have removed this label, now it is working

Label is a sub routine with a return ...
I am sure I am wrong somewhere !
thanks in advance
Francois
