I've used the arduino uno with the python serial library months ago and some packets got lost in the way. I've been searching about serial communication for arduino and I've been thinking that I could use some parity systems and other things to guarantee that my packets will arrive. First of all, if I use the parity system of the arduino's serial library, how good it will be? I need to send packets like "this button was touched", but ALL packets must arrive, so if some packet fails, I need to send it again.
How to make it possible? I'm thinking about using the parity system of the arduino's library, but I don't think if it's gonna work well.
Can somebody point me some good text about it?
