I'm writing a program and have to use visual basic drivers. So I'm stuck with VB. This program needs to have delays in mulitples of 0.005 seconds, although I'd accept delays in multiples of 0.01 seconds if possible. To do this I tried a code like this:
TimeStart = Timer()
Do While Timer() < TimeStart + 0.005*n
Loop
where n will vary as the program progresses. Unfortunately, the program wasn't running as I expected. After a bit of searching I found that the Timer() function isn't accurate enough - it gives time in multiples of 0.03 seconds. If I added this code in the loop:
print Timer()-TimeStart
Then I'd get results like this:
0.00
0.03
0.06
0.09
0.12
0.15
Is there any better way to include delays? I'm not too experienced with visual basic.
I've tried to do this:
For i=1 to 100000*n
next
however it doesn't seem like the timing is consistant with each run.
