View Full Version : incrementing question..

01-09-2008, 03:54 AM
hi all its been a while.. Ive been super busy. I could explain but it would take longer then the question i have.. so.. I wont:)

so I have this problem of not being able to find how to itterate a var. at least not in spin. Im use to something like

i = i ++

.. what im trying to do is find out how many pings I can do in 1 second using the ping.spin object. so im thinking something like

OBJ ''define the objects used.
rPing : "Ping"
Debug : "FullDuplexSerialPlus"

long i '' variable for incrementing

PUB Main ''define the repeat loop.
repeat until cnt := cnt + 12_000_000 ''using default clock speed
rPing.Ticks(16) '' using the ping object and passing pin 16 to it.
for i = i++ '' this is where I would increment i, but I dont know what operator to use..please advise

You use:

i += 1

Which is the spin equivelent of the C/C++:


or the general

Edit - Ooops. Was thinking in the wrong language..!

> i=i+1

But it is i:= i + 1


Never use force, just go for a bigger hammer!
