Gotta laugh, or cry, not sure which.

 

Meslomp, that is my thread on the MC Forum.

It is a SHORT version of my Thread about my difficulties with the SNAP.

None of the replies addressed the specific issue I have, namely the inability to download a pre-compiled .hex file to a Nano, and not also totally trash the Fuses.

 

The LONG version of difficulties with the SANP are detailed on a Freaks Thread that I hijacked, HERE.

 

Morton asked for some screen shots, so I provided a few.

I haven't hear anything back.

 

MC Support finally got back to me about my difficulty in getting my (first) Thread posted on the MC Forum.

That was a lengthy process.

 

I still can't download a pre-compiled .hex file into a Nano.

 

I gave up and moved on.

I use my AVR ISP mkII and my Atmel ICE.

 

My Stupid Non-working Avr Programmer, (SNAP for short) is just as non-functional today as it was when I purchased it.

 

I see that Cliff received some meaningful support from MC in another recent Thread of his.

Perhaps there is yet hope.

 

Perhaps not.

I had a few other "S" works in mind, but this is a "G" rated Forum...

Hello,

 

With such cheap price I couldn't resist to order one!

I had to remove the R48 as described on the snap page http://ww1.microchip.com/downloads/en/DeviceDoc/ETN36_MPLAB%20Snap%20AVR%20Interface%20Modification.pdf

I also made a small adapter to plug into UPDI pins.

With MPLAB X it works great, reading, writing (5V).

I bet you are using default fuses. This is no big deal for the UPDI chips, because the clock frequency is (mostly) set by software (the fuses only select 16 or 20MHz base clock). But for classic AVRs, you will quickly come across the problem that DocJC has been complaining about (to no avail so far). That is, the fuses are always auto-reset to factory default each time you upload a program.

I haven't removed R48 yet. Looks like that's next. Your SPI adapter is lots neater than mine. I'll check mine with an ohm meter again as it's easy to get the even and odd pins wrong when you're an autistic with spacial problems. 

 

My thread has never appeared on Microchip's forum. Perhaps shoes are required?

In my humble opinion, I'm always right.

Your account and first post as a newbie has to be Moderator approved.

 

For my SNAP post, (first post), it took almost a week before my post was approved.

Apparently their Moderators don't spend as much time on their Forum as our (outstanding!) Freaks Moderators do.

 

That delay is real helpful when one is trying to solve a problem...

 

Back in the day I seem to recall being told that MC/AVR was working on automatically making our Freaks log ins work on the MC site.

That, apparently, never happened.

Edit.  typo and attitude...

I decided it was about to SNAP my patience & put it aside, until I need a new dose of aggravation. 

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!

To help deal with that aggravation, I just ordered a new Atmel-Ice.

 

"The Freaks" are probably the main reason I have stayed with AVR so long. If the new overloards wished, I would help "freak" their site.

 

Oh, yes. Here is what MPLAB says when I try to program a 4313 on the pc. Haven't tried it on the mac yet.

Torby,

 

I was more thinking about this:

 

it is a post by this guy:

 

It was a rather long post were he seemed to have a couple of more tips/tricks.

I stopped reading at the first quote and did a quick scan on the rest.

You know. I think I saw that... I'll (forget to) try it tonight.
