HI ! I'm thinking of making a electronic ignition system wih a PIC and I want to know if the PIC12F675 / 629 is the right thing for me. I will not use any analog signals or serial I/O. I must have : * One digital input (for vacuum sensor) * Two digital inputs (ignition timing sensors) that triggers 2 different interrupts that triggers a timer interrupt. * Three digital outputs (for LED and ignition transistors) * Timer interrupt (for delaying ignition) Best regards Fredrik Gustavsson / Sweden -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
