AVR-Chat

Ok, I have managed to build a few of the internet AVRISP dongles in an attempt to have a ISP cable that works right, as the Kanda one I have for the STK300 dev board is one of the unreliable ones. Each design I have made has not worked for various reasons, usually having to do with no connection established between hard and software. I have tried each under PonyProg, AVRStudio4, and AVRDude a coupld of times too. Pony prog doesn't seem to support alot of devices, such as the attiny45 and/or the Mega16 I have in designs underway. I can flash the Kanda STK300 board, but that has never been the issues, the issue is to get a platform that is stable and can load the attiny45 and/or the mega16. So, please can someone who has already been through all this crap send a link or something to a proven performer that will definatly work with the attiny45!!?? 
 
 I am fairly sure that I have the software end covered by now, I have downloaded so many loaders and programmer softwares now that I will be able to sort something out. I like the AVRDude because it seems like it is a right fit for what I am trying to accomplish, supports the tiny45, it is just the dongle that I need to get sorted out, so if the submitted design is proven with AVRDude then that is right what I am seeking!!
 
 Among some of the articles I have been reading on the subject, I came across something stating that the dongles each have a pin which is used to recognise the device targeted, and that the stk300 dongle will not recognise the tinyavr devices because of different placement of this pin on the dongles(models). Is this true and my STK300 dongle is no good for tinyAVR devices but only megaAVR's? If so where can I get the design for a tinyAVR dongle??? I thought for sure that by just taking out the Mega103L from the socket of the STK300 dev board, swapping in a bunch of jumper wires over to my breadboard containing the attiny45 would be a sure fire way to get the device loaded, and quick! Perhaps this is the reason why that didn't work out?? Help

Hello Jay,

I don't know how you rate your time, but it seem you've invested quite 
a lot of it up to now.

Why not get you an ATAVRISP (MK-II now)?
For about $30 you get a manufacturer supported tool that gets 
occasional updates via Studio Service Packs to support new devices.

Could be cheaper in the long run - don't you think?

HTH,
Stefan

AVRISP mkII is cheap (>GBP30), it works with AVRStudio nicely and 
supports the tiny45.  We have a few at work that have worked 
flawlessly.  I've got a clone from www.ere.co.th that also works 
well.  Sometimes it's worth spending a little bit of money on 
commercial kit...

***I don't know where you may have read this bunch of mis-information.
The usual dongle has 6 or 10 pins and are defined in the Atmel
application notes.  Each AVR micro has some identifier bytes which can
be read to recognize the chip.

***You seem to be floundering around in your no-cost effort to get a
ATtiny45 programmed.  There is no indication where you are located on
this planet or whether you can get some one on one help from someone
nearby.  Also in your cross-posting between this list and avr-freaks
forums I've noticed several things: (1) usual response is to tell you
to go out and buy the $30 AVRISP or similar, neglecting your no-cash
situation; (2) there has been several responses and suggestions you've
neither acknowledged nor thanked for, including one about using Bascom
AVR trial (free) version to trick your STK300; (3) you seem very vague
on exactly what "dongles" you have built and tried with what program.

***Have you tried the Bascom AVR with your STK300?  Did it work?  What
results if not?  Either way, thank the guy who told you this and
follow up on it in the forum post with your results.

***See if you can find someone nearby who might lend a hand at
checking out your STK300 and might be willing to program the 45 for
you at least once or mentor you with getting a programmer working.

***Although I've not used AVRdude yet, version 5 says it supports the
tiny45 *and* "Supports a wide range of programming hardware, from
cheap ISP plugs that connect the AVR's ISP interface directly to a
computer's parallel port (no additional circuitry) or serial port
(some additional circuitry needed), more advanced ISP adapters..."
That appears to be a great path for you to try.  If you've already
tried AVRdude and it didn't work, then figure out "why"...

***This reply is not a good example (long!), but you might try
narrowing the scope of your questions you post to the freaks forum or
this discussion list.  Take it one step at a time.

***Hint: once you are able to program the tiny45 chip, for future
programming of it, it is possible to use a "bootloader" program of 128
bytes or less and only one pin of the 45, along with a serial PC port
dongle consisting of only 3 resistors and a zener diode to program it
in the future -- look for something like "tiny bootloader" in the
freaks project collection.  (I'm doing that right now with a tiny45)

***Good luck!

Don

Hi.  I had a PDF from somewhere (I don;t think it was directly from 
Atmel) on the construction of an inexpensive USB programmer for AVRs.  I 
seem to have lost the file, and cannot re-locate it on the web.  Can 
anyone provide me with a URL pointer, please?  (this particular USB 
programmer was capable of 1.5 Mbps max, which for programming purposes 
is more than fast enough)


Thanks an Advance;

aka avrFreak on efNet IRC
check out the efNet IRC channel avrFreaks,  a new, AVR dedicated 
realtime discussion forum.  not much traffic now, but I am hoping it 
will grow into a viable and useful forum.

Perhaps it was this one:

Passive parallel dongles must be short (the cable), I don't remember 
exactly, maye max 30cm.
Also, in AVRdude U must have the pinout specified in the config file.

Good luck.
