Hi,
I'm programming a lot of attiny85 MCU and would like to speed up this process
I'm currently using cheap usb asp programmer and AVR dude software
Which programmer do you advise that is much faster than my current config ?
Is ATATMEL-ICE fastre ?
Thanks,
Franck
Is ATATMEL-ICE fastre ?
That is the top of the range but you need to compare yourself.
I like the AVR Autoprogrammer.
USBASP is limited to low USB communications speeds, probably making that the limiting factor.
Any programmer with a full speed USB connection is probably better (including things that operate through a HW USB/Serial link, like "Arduino as ISP.")
If you're programming a lot if chips with the same binary code, you should probably look at a programmer that has local storage of the binary (or build one, similar to the various "optiloader" implementations.

These store the "binary to be programmed" (in various formats) in the flash of the chip that does the programming, completely eliminating "communications" as a bottleneck.)

I wanted to be able to program and flash the Tiny directly in Studio, and only use my AVRISP, so I came up with a solution...

In Quark Load, you are able to program, assemble, and flash without ever leaving Studio.
To the programmer and IDE, nothing seems different, but the result is all IO Pins usable on the Target ATiny.
Normally, the Res[e]t Pin is dedicated to the ISP, so it can only be used as a limited input, but Quark Loader fixes this.

Hello,
What do you mean by "a lot of attiny85"? What quantity? 20, 200, 2000, 20000? A PC with an cheap USBasp programmer is about as fast as it gets for programming an 8K flash chip like the Tiny85.
In the USA, you can always get people to do tedious work by going to any highway entrance where there are lots of men holding signs that say "will work for food". So have one of these guys program your attiny85 chips using a battery powered programmer right by the side of the highway. Then give him an apple and a few packets of ramen noodles. In Germany, use some "refugee" who used to be an engineering student.
No, seriously, this is what interns are for...programming lots and lots of microcontrollers.
1K per month and my target is to do more.
When you have a other task to do and waiting while holding your hand with the board on the bed nail it is long
In my case programming + readback and fuse writing takes 15 s or more I have to check
1K per month and my target is to do more.
1000 quantity
tiny88 at 0.86USD each
tiny88 programming at 0.20USD each
tiny88 tape and reel fee at 0.02USD each
tiny88 ink dot fee at 0.01USD each
The other AVR is mega328P (i.e. "only" two AVR)
Might inquire at your distributor for tiny85.

writing takes 15 s or more I have to check
The Auto programmer mentioned above does ~8k in less than 4 seconds with Xmega (PDI) and I'm not using the fastest speed IIRC, this is from turning power on to start testing the board.
Never used it with "normal" AVRs.
Yep, sounds like you need Alank2's autoprogrammer!
At 1k /month, your board house should program your chips for you.
I use Applied Digital in Branson MO, but any of them should be able to do that for you.
