Just a little thing about eDI

[scr4tchy]

Hello,

I developped an automation program with your driver (thanks)
I've just a little problem.

At the start of my software, I set eDO for port 8 & 9 to Low.
On an Event, I read the value of 8 & 9 (eDI) and I set (eDO) to the contrary. After a while, I set 8 & 9 with previous read states.

Ex:
Starting.. 8 & 9 = Low (by eDO)
Event
Reading 8 & 9 ( => previousState = Low )
Setting 8 & 9 to High
Wait a bit
Setting back 8 & 9 to previousState = Low.

That's work. Right.

But now, when I want to do this :
Starting.. 8 & 9 = HIGH (by eDO)
Event
Reading 8 & 9 ( => previousState = Low ) <=== PROBLEM. It should be High!
Setting 8 & 9 to High
Wait a bit
Setting back 8 & 9 to Low.

Do you see what I mean ? ^^ It's a bit stange x) Or maybe I'm a noob. Do you have any idea on How to do the trick ?

Thanks for all !

(You're credited into the program^^)

eDO will force the channel to an output and eDI forces it to in input. So your problematic eDI call is setting the channel to an input and reading the state instead of reading the output state which I think you are expecting. Using the eDI source code, try creating a similar function that does not set the direction and reads only the state. The low-level Feedback command in the code will need to be modified to do this. If you run into trouble, tell me what LabJack device you are using and I'll help to point out what part of the code needs to be changed.
