USB developmentboard ATtiny85

I have a USB developmentboard ATtiny85 but I can't get my code on it. I Installed the libraries and everthing seems ok but now it shows that windows10 won't communicate with this USB-board.

I've found several instructions to program it from my arduino but they are all based on the ATtiny85 chip on a breadboard and not on a usb developerboard.

Where can I find a good instruction to program it from my arduino?

I have a USB developmentboard ATtiny85 but ...

I am not going to tell you which one because I want you to guess.

I think I'm missing the clue. But part of my question is solved. It does work with W10. I found a good instructionvideo on https://www.youtube.com/watch?v=MmDBvgrYGZs.

But I'm still curious how to program it from the arduino

The USB development boards require a different core than you use for programming the chip the normal way (via ISP programmer). They have their own special bootloader based on VUSB, and I think other code to handle USB-related stuff that happens within the sketches. Most of them also blow the RST_DISBL fuse so you can only program them via USB. You must determine what board design you have, and download and install the appropriate third party hardware package.

I have a low opinion of such boards - usually the USB connectivity is just a ball and chain tied to your leg and stored in the microcontrollers already limited flash...

I think I'm missing the clue.

Yes. Please read this:- How to use this forum

Then tell us WHAT development board you are using and provide a link to it as requested. This is a fast moving business and there could be more than one.

There are definitely more than one. Adafruit makes the Trinkets, then there’s the digiSparks, and just the other day I became aware of this one.

I don’t get it. A small programmer such as SparkFun’s Pocket Programmer is only slightly more expensive than a usb cable, and the '85 chips are so small and cheap …

plus, if your sketch/data are small enough, you can use a '45 or '25 and save a few pennies. (x however many you make.)

I'm sorry if I wasn't clear enough. It's a Digispark kickstarter development board ATTINY85 module for Arduino usb from Aliexpress.

In want way was that a link? Did you read that page?

yes I did read the page but English is not my native language. A link to the board is http://www.aliexpress.com/item/1pcs-Digispark-kickstarter-development-board-ATTINY85-module-for-Arduino-usb/32459720851.html?spm=2114.30010308.3.1.jkN6jr&ws_ab_test=searchweb201556_0,searchweb201602_5_10057_10056_10055_10037_10049_10033_10059_10032_10058_10017_10060_10061_10062_10064,searchweb201603_4&btsid=d7a2b197-341c-473d-9985-01f4f08d63fd

This is really a headache problem if you do not know the code and how to use this device. But anyway I wish I could at least provide some useful information for you. Here are some details about ATtiny85. You may take a look at this page.http://www.kynix.com/Search/ATtiny85.html

It's a digispark. Instructions here: http://digistump.com/wiki/digispark/tutorials/connecting

OK, thanks everyone. I think I've enough information to continue my arduino-puzzle.
