HID USB Multimedia Keypad

[pmacleod]

Would it be difficult to do the USB Service with an interrupt routine instead of in the main loop?

ISR is the way to go. Here is a project using DT's Instants.

Darrel gave us another USB service routine also, but it seems to work best as a stand alone ISR. That is why I like using the Instant approach.
But you can take a look at the other here.

Thanks again for the help.

I put the code you sugested in but I keep getting an error saying Syntax Error for

UIE = $7F 'ENABLE USB INTERRUPTS

I am using Picbasic Pro 2.47

Can you give a little more info.. Are you trying the instant solution or the other?
Go ahead and post your code and config setup.

Ok I updated to PBP 2.60 (just found the CD) and it compiles ok now but if I enable the innterrupt routines it won't detect the device.

I am using a custom HID Bootloader (Modified the Microchip one since it won't compile using the free tools)

I am also using an external 48MHz Oscilator since I have hundreds.

Ok I just had some of that code you gave me in wrong place, seems to be working fine now.

I noticed they really changed the USB examples in the new PBP, is it hard to convert an exsisting project to the new format or is it even worth doing.
