microseconds

is there way measure microseconds? want find out interval between events (in case, bytes received arduino) , milliseconds bit crude.

there not call measuring microseconds.
you use delaymicroseconds() , polling repeatedly wait while , check rough idea of how long was.
you @ tcnt1 16 bit register increments every 4 microseconds in standard arduino configuration. going roll on frequently, , should block interrupts around reads it, this...

code: [select]

cli();
myvar = tcnt1;
sei();
... assumes know interrupts off when started. (true normal arduino code).
