My brother-in-law is originally from Mexico and still struggles to speak clear English. His ESL teacher suggested that he watch American television exhibits to pick up on idioms which can be commonly used. He loves to Get Free Diablo 2 Items Online. so, every chance he gets, he borrows our laptop to try and do just that. My husband and I prefer to see him succeed in this goal so we are considering purchasing him a laptop for his birthday. He would need to buy World wide web access, but I imagine they can afford that on their monthly budget. I haven't addressed this with my sister yet, but hope to this weekend.

@ian
I’ve been following the development of the Bus Pirate but everything seems to have gone quiet about a month ago. I see that you are still working on the software based on the the Google SVN but I can’t find anything on the refinements made to the hardware for the v.2go.

Do you have a BOM for the v.2go hardware you could post?

I think I have all the components based on what documentation there is on the web including the v.2a, schematics and comments. The last item I have a question on is the 4066D – what is the specific version that you have used?

I have purchased the v.2go board from Seeed Studio and want to place my Digi-Key order but would like to confirm the parts before I do.

Any help would be appreciated. Thanks,

Mike

@ian:

Any word on the v2 boards? You’ve got at least one person chompin’ at the bit to order one!

Thanks!

@ian:

That V2 board looks like it’s got a USB port. (SWEET!) Are you going with the FTDI chip?

Please consider selling the new boards, or at least pointing to a place we can buy ‘em. The more the merrier!

Thanks for all your hard work and great posts!

@lesnet Ok I will create a patch for you. Still I have a little question. Do you want to use CC0 (which makes a more robust public domain release then just saying that the stuff is public domain) or not. If yes It would be very usefull if you would tell me the name of the group/person holding currently the copyright. Then I can create the appropriate header and make a patch.

@esden – If you make these changes and submit a patch, I’ll apply it to the code.

Just wanted to give a heads up, make sure that the linker script is actually for the chip your using. Foe example I think the one that is on MC’s site is for the 24FJ256GA110, if your using a GA1XX you may beed to check that the script is right. There are differences in same family depending on which of the pinout models your using.

We added a function to help test interrupt implementations. The latest code has an undocumented menu command ‘i’ that configures and enables timer1 with interrupts. In main.c there’s a global variable irqFlag which prints ‘IRQ DETECTED’ into the terminal when set to one. At the bottom of main.c are three interrupt handling functions from Microchip’s examples. Both of Microchip’s examples cause the chip to reset. This should provide an easy framework for testing interrupts.

to follow up to crazor’s comment, the source in their svn repo already has the relevant bits. the .gld file is the linker script in question.

i cant demonstrate working code (no pic environment unless someone sends me a pcb :-), but to get the uart1 rx interrupt handler installed just define a function named __U1RxInterrupt. the linker script will fill in the interrupt vector for you via this snippet:

long( defined(__u1rxinterrupt) ? absolute(__u1rxinterrupt) :
absolute(__defaultinterrupt));

which translates to:

allocate space for a long word whose value is the address of the symbol named __u1rxinterrupt if it is defined and __defaultinterrupt otherwise.

the spi/uart2 interrupt handlers are basically the same deal.

That is very good to know! But even when it is public domain it has to be stated in the source. Otherwise the whole thing automatically falls under copyright and one can do with it basically nothing. :(

@esden – previous bus pirate posts mentioned that it’s public domain, but the closest option on google was BSD.
