seperate task AO and CO

[halcyon]

Hi

Can anyone help me to diagnosis the problem.

I have a program to generate a counter output which is triggered by an AO of 2 channels. the output of the countered is fed to the RTSI route. This program works well. Then I wanted to seperate the AO task of the 2 channesl into individual task  of 2 AO, so that I have more flexibility of controlling the amount of samples data to output on each. The problem is that I can not get this to work. I have tried a simple example of outputing a single value in each of the AO task and that seemed ok. I wonder is anyone can tell me what is wrong in the program and tell me how to correct it. Thank you.

You can't start two different AO tasks from the same device at the same time. I also see that you are using two separate timing for each of the AO tasks - which you cannot do. However, you can manipulate how fast the data outputs to the port by doing some manipulation in your code using one task.

Thank you SumTum,

I just wanted to decoupled the 2 channels output and make life easier for myself. So there is no way of having 2 seperate AO task for different channels unless I have 2 separate card!! Oh Well I guess I have to live with it then!

Thank you.
