The code is all Atmel assembly language, altho I had to jump thru some hoops to get a xx.x "floating" voltage value, and an F temp value from a C temp sensor in binary; i.e., the Mega8 has no floating point math (I'm sure there are tricks, but I'm mostly a hardware guy). The temperature probe (Dallas 18b20) is on a 3 foot cable so it can be placed in various places on the motorcycle. Also, since it is an addressable 1-wire device, you can have several placed around the bike. For instance, cylinder head, crankcase, brake caliper, etc. Super fun project! And as any hacker knows, the reward is seeing it all work! I've built projects 10X more complicated, but always, each project gives me satisfaction and pride. We stand on the shoulders of giants.
