USBDemo, something to learn USB a little bit

[jellis00]

The ones on the left require 8-LEDs on PORTB, and 2 other LEDs on the CCP outputs, RC1/RC2.

The USB D-/D+ are on RC4/RC5, so I don't think you can just enable the whole bank of LED's on PORTC. You'll need to attach LEDs to only the 2 CCP Pins to get the faders working.

Turns out you can enable all the whole bank of LED's on PORTC and it keeps working. You can then see the LEDs on RC1 and RC2 vary in brightness as you change the sliders.

But you should be ok with LEDs on PORTB.

Except for the LEDs on RB0, RB5, Rb6 & RB7 (which are used in your code) you can now click the check boxes on B1 thru B4 on the VB6 Gui and they work to light the corresponding LEDs.

I now have Steve's VB6 GUI and the DT_HID monitor running side by side and everything works as advertised except for the exceptions I listed above for the B0 thru B7 check boxes. Your support to me in getting to this has been outstanding, Darrel. Thanks so much!

Now I only have to figure out how to capture the data coming across the USB interface from the PIC into a spreadsheet. Your suggestion to use CDC and HYPERTERM would be an easier option except that my application requires a USB interface that is also used to connect to a cell phone, and I don't have physical room for both an RS232 and a USB interface within the physical board size contstraint or panel connector space. Looks like I have to figure out how to do the capture in Steve's USB VB6 GUI. I will modify the PIC side to send comman delimited data per your suggestion, but don't know how to approach capturing the comma delimited data from the VB6 USB Gui that is showing into a spreadsheet. Can you refer me to any forum ideas or reference tutorials in this area??

Thanks again, Darrell. Your contributions & presence on this forum is what makes it worthwhile.
