AVR Freaks

Thanks for the comment Max.  I gotta tell you if someone told me before I had this that it would benefit me, I would have said the same thing.  I'll just haul my notebook and atmel ice into the other room.  After using them, they are just so handy to program and take to the board to be programmed.  I never haul my notebook anymore!

Here is a video of the V3 programmer which has a 5 segment LED graph to show status and can do PDI/ISP.

Video shows 64K being flashed to an XMEGA-A3BU Xplained at 2MHz PDI.

Hi Bob,

Yep, I make them.  I've never used a contract assembler though I'd love to have a product that sells so many that I need to!  I probably make 10-20 pcb's a month for various projects and I gave reflow a while, but I find that with SMD and being without a pick-n-place I can solder them just as fast by hand for the quantity that I do.

Have a great day,

Alan

Here is a screenshot of the pc application:

I wrote it with C++Builder which I've been using for many years!

Let me know if you have any questions.

Hi PhillyNJ - I appreciate your thoughts and ideas:

#1 / #2 / #3 - you are right, a good video showing basic use of configuring it, programming it, and then it programming some boards quickly is on my to do list!

#4 - I sell them on eBay and here, a website wouldn't hurt, but I wonder how beneficial it is since most people who would use it would be here anyway.  It is a balance of the work to put the site together vs. benefit.

#5 - I think it might be too specialized for kick starter - but perhaps I am wrong.

#6 - I agree that a TFT could make it nicer, but the thought (design goal) was to keep it simple and effective.  Something I won't mind sending to a customer to have them upgrade something and hopefully they'll return it in a return envelope.  I'd rather provide good service and help to my customers than to make it cheaper.

Thanks for the positive comments tpappano!!!

I like the idea of a smartphone programmer application, but it would be quite a bit of work.  I use an older C++Builder IDE, but I think the company that sells this makes a much newer one that supports a multi targeted type project that allows you to compile for PC, mac, smartphone, etc.  I know even if that would work there would be things to work around.

I once thought about this and thought about the idea that you can erase a flash, program some bits, then program some other bits, and so on, and as long as your multiple program requests end up programming all the bits necessary, it will flash properly even though you didn't actually flash the program as is.  Now, someone could still monitor the SPI and put combine the bits back into a single program stream, but that would take some level of skill.  In the end I didn't implement it because it would take X times longer to program.  If someone wants the code bad enough, they could always sent it for someone to defeat the lock bits anyway.  Even monitoring the SPI would take some skill to dig through all the commands and extract the program, but it could be done.

If you really want secure, you've got to put a bootloader in that is sent an encrypted stream of program data that it decrypts and flashes.

The PC application / manual links above have been updated to 1.10d - this version ignores the 03 and 05 records in the Intel HEX format that it was choking on before!

Glad you got it installed!

Yep, you got me there in the manual!!!! :)   I've fixed it and re-uploaded a new setup!
