USB confused (running out of hair)

[dhouston]

AAwwww come on guy, don't be lazy, leave the FTDI for students.... there's everything you need to do real USB here.

Au contraire - USB is for the students who need to learn the nitty gritty. I've made it to 70 with all my hair by taking the easy way out.

I bought Jan Axelson's USB Complete when she first released it and quickly decided I would avoid real USB forevermore.

I develop for Windows, Linux & OSX and the USB-serial chips (or external adapters) are the only practical way to handle all three.

Steve, I agree, sort of. Everything to do USB is here for the PIC side. As for the PC side, maybe everything is here. If one wants to develop in C of VB, I think everything is prolly here. Well, If I want to work in C, "I" prolly wouldn't be here. So if thats needed, then its not all here. And VB? well what flavor?? 6 and .net? Maybe I am just too stubborn, but as a hobby, I have NO plans to buy anything from them guys. Nor am I going to get the exppress version (which may not work).

It seems I need to look further into CDC. but NOT for pic32 as the app note Dave linked would suggest.

If I find the energy to keep persuing this, I will hop back on the CDC for dummies thread and ask zillions of questions there. In the mean time, How does 1 go about accessing the "port"from their app if using CDC? I know it will be app specific, but whats the process? Does it become COMx and just use regular serial commands to use it?

With CDC the PC will think it is talking to a "regular" com port. COMxx

Here is another example that might be of use...

Dave, that is a great example of both USB and sd card reading/writing. So can I assume there is a LB part also?

[mackrackit]

Nope, no LB or any other custom thing on the PC for this one. In practice for me this is only plugged into a PC when real time trouble shooting a system so a terminal program like the one that comes with MCS is fine.
