USB Pics, ICD2, pic basic pro

[Darrel Taylor]

when you tried this, did it go smoothly? what were your conditions?

I started with mister_e's code. A pluggable Breadboard. And real USB cables.

From start to first Yahoo! was about an hour and a half.
Had an FCMEN error...
Had a problem with the capacitor too...
Then ... when I saw that little "Unrecognized" window, or actually, didn't see it. I was a very happy little Nerd.

... i come to this stuff from basic stamps and basicX controllers...

[vacpress]

well. of course this example highlights the benefits of basic stamps. parallax would have put together coherant instructions. i am on like hour 15 of this now(not in a row, of course!). i have read so much about so many topics, and none has really helped, it still does the same thing it did 12 hours ago. very frustrating. unfortunately I cannot give up, combination of stubornness and having too much invested allready (time and money)

i suppose the next step is to rebuild the entire circuit on breadboard, giving up on my easy to work with protoboard... i suppose i also need to find a 4 and 20mhz crystal...as opposed to these resonators that always have worked fine for me in the past..

why is this so hard?

[vacpress]

So, Ive used the UBB USB Sniffer to see what is going on.. This is the log it makes, any ideas?

I see that it is getting back alot of 0s.. Just like when i try to verify a pic that isnt in the programmer socket... i will now scour the USB protocol so I can troubleshoot these foreign messages. Damn, this isnt how i like to spend my little spare devlopment time...

this is what the logger reports when i set it to track the next device to be plugged in, and then plug in my project.

anyone know of any GOOD walkthroughs for this stuff? I am very close to plunking down the $60 for the Microchip.com demo board.this troubles me because i am poor enough as it is, and that is like, half my food money for the next 2 weeks!

Naaa, they just make you use an FTDI chip, so they don't have to deal with it.

> ...i suppose i also need to find a 4 and 20mhz crystal...as opposed to these resonators...

I'm running mine on a 4mhz resonator here. Works just fine.

[vacpress]

off to the other room with it. i have a whole electronics lab, and ive been working on this in my bedroom for some reason.. i will now go rebuild the entire stupid circuit from scratch testing each section, use different USB cables to cut down the chance one is sketchy, etc... what a pain in the ass...

any other hints you may have? photos of your project? anything? suggestions?

thanks.

I got it working! The stinking cable had the standard colors, red, black, green, white, but they were all odd configurations... black was NOT ground!

anyways, now on to the hard stuff.... getting the easyHID code to work in visual basic .net!

Thanks for all the help I am actually very grateful and dont take it for granted at all that you read pages of my inability to use check my USB cable!

I build the circuit on breadboard with a different cable, it worked right away! i tried my other cable.. didnt work, rewired it, it worked, tried my protoboard with the correct wiring: BINGO! like 12 hours later!

glad i went out for those 2 pints in between!

a shame the easyUSB project has 2 run errors in .net


any .net know how mr?

[Darrel Taylor]

Awesom!

any (visual basic) .net know how

Can't help you there, I'm a Delphi guy.

Please hold for the next available operator......beep...

Oi! Darrel ....NO!!!!

Hangs head in shame

Dont show pictures of extremely neat breadboards. Where is the possibility of accidently shorting stuff out during development.

Your looks almost like a PCB. The "defining connections" stage of routing a PCB is called a "ratsnest" for one good reason....so it can look like the breadboard that you prototyped on

HA! I eventually used that as inspiration to do an extremely neat breadboarding myself, which worked first time...Imagine!

Really though, the hard part is this software. There is quite alot going on! It is really much more than I am used to, i thought my neworked BS2s had complex code....

Thanks guys, you are a real resource in a sea of difficulties(microcontroller development)

ROFL,

I'll take that as a compliment.

But really, it's just that you don't want to have anything that correlates to Rats in your proto-board, when you have 2 Evil glowing eye'd monsters in the house.
