Does anyone have an example VI to communicate with the Blackfin through USB and send a digital 1 through a certain port?
Thanks in advance.
I don't have any specific examples for you, but I can definitely point you to the VIs in LabVIEW that allow you to do USB communication. Take a look at this KnowledgeBase Article on using USB with LabVIEW. That document will walk you through configuring the USB instrument, in this case the Blackfin, to be recognized by the Windows PC and as a LabVIEW VISA resource, which is how you should communicate. There are some great examples linked from there for other types of USB communication.
By the way, are you using LabVIEW Embedded for Blackfin or regular LabVIEW? Thanks, I look forward to hearing back from you!
I see that you're working with another one of our Applications Engineers on this thread. I've made her aware of this post, so to consolidate everything please post all future correspondence to that link. She is in contact with our R&D department and will address your latest question.
Thanks, and in the future please limit your posts to one thread. This helps us properly allocate resources as well as keep the question and solution in the same post together so other users can benefit from the work. Have a great day!
I am working on developing an user interface for transferring data between blackfin BF-527 processor and the computer(OS:Windows) using USB interface.
Can someone guide me on how to proceed with the same. Please.
I see different ways do this, depending on your application needs.
There are examples available fom ADI for implementing bulk transfer on the USB. I did taht once on a bf548 but this should work with the bf527 too. You interact from PC side via a dll with the driver.
There is a simpler solution using a uart to USB chip that provides a virtual COM POrt on the PC.
