I'll look into using the 8-bit PWM for my application.
Can you provide me the example external-transistor circuit you offered?
Thanks.

Thanks for the reply. Unfortunately I wasn't specific enough in my original post. I would like the "fPWM" module to be open-collector... this is SPI pin #4. I could also use the 8-bit PWM module but not as desirable. I am trying to pull down a 6.5V high-impedance load with the PWM signal. When PWM D...

I looked in the manual for the Atmel processor on my sub20.... looks like the GPIO can have its internal pullup resistor disabled.

Hi,
Can the Sub20 devices be configured to operate in open collector configuration? ie if output is disabled (low), then pin has high impedance.

Thanks,
Brad

I removed the previous sub20 installation using the installer tool, installed SUB-20-101021. At this point LV 8.2.1 had no problem with the sub20dnc.dll. I copied in the DLL posted in this thread and the error occured.

Thanks for checking. I will see if the problem reproduces with 8.2.1.

When I try to add the assembly reference to LV 7.1.1f2, 8.0, or 8.2.1 I get an error. LV either crashes or says that the file may not be a .NET assembly. Specifically in LV 8.2.1: Add .NET constructor browse to the x32 version of the 1.4.6 file The objects box says: "An error occured trying to load ...

Is this built for .NET 3.5 or .NET 4.0 ? Does it matter?

Serg, In most cases, Labview automatically deletes .NET references when the top-level application stops running. I have tried to store the .NET reference in a global variable but once the top-level app stops running the reference is no longer valid (sub20 device doesn't respond). The only labview wo...

Thank you.
