Experimenting with a BitsyX for a potentional customer and I'm having trouble opening this port. I'm trying to use the C# and not having any luck being able to open the port. I keep getting an invalid handle on the return.
The port name IOB1: suggests that you are trying to use the *non* ADSmartIO GPIOs. For newer BitsyX images the recommended method for using the GPIOs is the Digital I/O Driver.
Looked at some of the digital I/O driver stuff and I still can't open the port to read it. I ran the eVC++ example and the handle I'm getting back is 0xffffffff. Not null, but still invalid. Is it possible I'm missing some kind of file.
Edit: Looked at the CE version I have and it's 4.20.05
As the implementation matrix in the link above shows, the digital I/O driver was added in 4.20.14 for the BitsyX. You should update your device's image to the latest available to use the driver.
