Hello. I'm tasked with getting a windows app written in VB.NET talking to a micrcontroller. Our microcontroller has a USB interface and I'm writing code for it in C. Ultimately we need to connect the microcontroller to a PC with our VB.NET program on it, and get the two talking.
I am very experienced with embedded C and with VB.NET, and have spent lots of time getting the two to talk over a serial port, but I have zero experience writing anything that talks USB.
Can someone please give me a quick how-to on this? Please, no links, I have plenty of links to get me started on USB concepts -- it's not in focus yet but I'll eventually get there. I think what I need right now is a 25-50 word, real-world, person-to-person description of what I need to do to send "hello world" from my VB.NET application to my microcontroller over USB.
(When explaining it, your audience is someone who may be hung-up on the simplicity of the RS-232 serial connection -- I think I've been spoiled, and it's impeding my comprehension of USB.)
Thanks *very* much in advance.
