 		 #116996 - You have to set the flag!
Responding to: ???'s previous message
Michael said:
ok i think i understand what you mean, the value is captured but not in time

No, no! What Erik wrote

Erik said:
in the ISR
if flag: ERROR
old = new
new = capture
flag = true

in main
if flag: new-old = diff
flag = false


is the shortform of how your code should look like! The flag is to be set in the ISR, to tell the main program, that a new capture event has occured.
Look also what I wrote about this flagging here:
