Parcing data from uC

[gillettestm32]

I am using this VI that i found in a different similar post here and i am still having some issues with it. I am sending this from a microcontroller: b,3.9998752,9.5648515 and i want to use a different indicator for each of them. I am sure i am missing something as i am new to LV. Any ideas?

thanks

1. You actually do not need that 0ms wait in the loop.  You already have a wait in there.

2. Your format string should actually be "%[^,],%f,%f".  The %s will continue until a white space.  So your first parameter (the string) is actually grabbing all of the data.  By using %[^,], you are getting all characters until a comma is found.

Thanks for the help. I changed the format but i still have the same issue. The input string is b,3.9989767 for example, but there are no outputs after that.

Hi gilette,

your input string "b,3.9989767" gives the expected results as described before by crossrulz.

Maybe your read string contains some more chars? Why not switch its display mode to \-Code display?

Are you getting an error out of the VISA Read?  That is the only thing that makes any remote sense at all.

I changed the display mode but had the same results. I am having an error as crossrulz pointed out however.

I searched online for this exact error and found this that solved my problems. I added \r\n to the string that is transmitted. Thanks everyone for helping.
