EMC- Counting redstone pulse

Hi

I'm making an emc/item counter with CC and redstone pipes.

One pipeline is for the MK1(left side)
The other pipeline is for the MK2 (right side)
I have 2 redstone pipes which are connected on the pipeline of the EMC-Flowers.
Like this a redstone signal will be pulsed when an item is in the redstone pipe.

The Redstone pulse is read by the computer. It counts the amount of items flowing through it. –(this happens on both sides)
Now I want to make a pulse counter on CC.

This is my code, but whenever an item passes through the redstone pipe, it counts for 2 points and not 1.

Also look at the photo of the setup

os.pullEvent = os.pullEventRaw
local pulses = 0
while true do
local event,p1 = os.pullEvent()
if event == "redstone" then
pulses = pulses + 1
end
term.clear()
term.setCursorPos(1, 1)
term.write("Counter")
term.setCursorPos(9, 1)
term.write(pulses)
end

That's because a redstone event fires when a redstone input turns on and when one turns off. Check if the input is on after receiving the event, only increment the counter if it is.

Yeah, How do I fix it in the code ?

Well, show us what you tried to fix it. How would you check if the input is on? I'll give you a hint, check the redstone API page and see if you can find something there that reads input states.

Like this ?

os.pullEvent = os.pullEventRaw
local pulses = 0
local rsState = false
while true do
if rs.getInput(left) = rsState then
rsState = rs.getInput(left)
if rsState == false then
pulses = pulses + 1
end
end
end
end
return pulses
term.clear()
term.setCursorPos(1, 1)
term.write("Counter")
term.setCursorPos(9, 1)
term.write(pulses)
end
end
end

I have not the slightest idea what you did with those ends, but the part that increments pulses on the falling edge of the redstone signal should work just fine.

EDIT: You should have kept the os.pullEvent call though. Without that, your program never yields and you get a yield timeout crash.
