Just one more question.Whith power supply is better.Switch(lm2576) or linear(7805)?

Switch...
You should defiantly make double side board.
And use ground plane, on both side, and lot of vias between top and bottom plane. And use SMD capacitor, you can put them closer to pins. Traces form oscillator pins to crystal short as possible...
By the way nice bike and project

Hi, AdrijaD
I've been using a '2520 aboard my lawn tractor as RPM meter, temp checker, Hour meter and servicing spy ...
enjoy ...

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

Really nice project Alain!
Very professional and very well designed! AdrijaD, did you notice how Alain incorporated .1 mf as well as 100mf (and other size) capacitors in his design? This is a great way to handle EMI (Electro-Mechanic Interference) / RFI (Radio Frequency Interference). As for your question about using a 7805, yes, a non-switching regulator is easier to filter the DC out. You also may wish to look at the LM123 or LM323 as the case is grounded so it is "shielded". Best, Ed
