tachometer at90s2313
hello all,
iam trying to build 7-segmant based LED tachometer for my motorcycle(single cylinder,4-stroke).i found a pic based project but there is no source code and it was too sensitive for automotive use.
mean while my friend mailed me a site(german i think) where i found another circuit which is based on AT90S2313(avr).before start building it i have some doubts to clarify.
download attachment for the code,schematic
my doubts are
1.what is the purpose of LED1,LED2 and switch s1(between pins 1 and 20)
2.as iam using 1-cylinder,4-stroke vehicle,where and what i need to change in the code.
help me
