The data does not care if it is HEX or ASCII, that is only how you see it on a terminal, the way it is represented.
HEX 40, or 0x40 is the exact same as decimal 64 or binary 01000000. They are all the same thing, really.
I know that hex equal dec equal bin, equal oct...
in the serial tool, if i send to controler in ascii, it does not work.
i've tried (with the serial tool) by changing the number in decimal and have sent it in ascii... it does not work...
this why i'm confused...
i'll try with your simplified version...
thanks very much.
