USBDemo, something to learn USB a little bit

[Noise.be]

i use 18F4550
470 nf in Vusb / Vss
.1 uf ceramic in Vcc/Vss
4k7 in MCLR / Vcc
resonator 4mhz

I've used
220nF Vusb / Vss
.1 uF ceramic too
10k MCLR/Vcc
USB B type Connector
and it works fine now ;-)

Out of curiosity... Anyone tried USBDemo with Windows Vista? Working?

[Squibcakes]

No, but I'll give it a go this weekend I can feel a backup coming on....

BTW,

I need a decent way to debounce a number of switch's connected to my pic.
I'm using a dirty PAUSE 50 to do just that, but finding unless I put USBSERVICE everywhere (ie after checking the status of each switch), the switch's arent being sent to the pc (via usb).

I borrowed the ASM timer interrupts from the usbdemo code, but that doesnt help either. I'm thinking that TMR interrupts aren't independent of PAUSE statements. Is this true?

I don't want to use the BUTTON command.

If you're using ON INTERRUPT... yes PAUSE will screw up things. Using Darrel's interrupt + it's USBDemo code modification ( AKA POST 148), should solve it.

Depending how you implemented the interrupt debounce/read plah plah, it may work as well with ON INTERRUPT..

Ok Great I'll have to try it. Good to know there could be a work around.

BTW I tried running usbdemo on Vista, but I need the mchid.dll, which I have on floppy disk but can't get it on to the laptop running vista.

Don't supose you can upload it on to the website so I can download it straight onto my laptop eh?

That DLL came with Mecanique EasyHID. I'm not sure if David allow to link the DLL even if the software is 100% free.

Hi Steve,

Thanks for the tip, it works a treat!

I rekkon melabs should incorporate DTs instant interrupts into their next version of pbp and do away with ON INTERRUPT altogether......

Cheers buddy.

Of course that would assume they do anything at all.......
Come On MELABS...you're falling behind!!!

What would the __CONFIG lines look like using the ECIO mode with a 48MHz half size oscillator on pin 9?
