YES YES YES you guys are my heroes. I found this site around a year ago looking for attiny85's. I bought some in my first order and through much trial and error got blink to work. I then made my own programmer shield using a ZIF socket and an adafruit proto shield. Still its never 100% reliable.

OK now that I have come down a bit, can you also "adjust" or config the fuses with this? I need to add a crystal to a 85 and barely getting the thing programmed. The whole fuse thing makes no sense to me.

Also anyone ever find a servo library that works with a 85. I want to make a little bug robot and I think the tiny servos would make great motors since they only need one digital port for direction and speed control.

You guys did NOT totally copy my programmer, did you? ;) http://cl.ly/image/241w1U3R022u

Old post but new problems. TinyAVR won’t program on Windows7 64 bit with Arduino IDE. It used to work just fine. Now it gives several different errors. For days it was driving me nuts thinking it was the chip or my circuitry, until I plugged it into an XP machine. Works fine there. Plugged into Windows7 Arduino shows using Com3 but Win7 shows no com ports, just USB controllers. Tried using other avrdude exe’s. Tried all sorts of other drivers (including Sparkfun’s 64 bit driver). Forced creation of com ports, but could not make a port 3, only 4 or greater. I must have installed something on Windows that mucked up the settings. Typical Windows. Any suggestions?? Meanwhile, maybe this post will help someone who, like me, thought their programmer, code, or circuit was at fault. Guess again. Try a different OS before you go nuts.

I am building a small module and every component can run 3.3v or 5v except for one. Can anyone recommend steps to bounce from this 5v programmer (when plugged into USB) to a 3.7 LIPO battery. I don't want to program in the dark and keep moving the ATTiny85 back and forth between my breadboard and this programmer. Any suggestions would be greatly appreciated.

Could you either tell how to fix the flippin' sync errors once and for all or replace these with the newer version? How many rabbit holes do I have to go down to get an answer?

I noticed this awhile back and thought it was a neat idea but delayed buying one. Now, when I want to work more with the ATTiny it isn't available. I should have gotten it when it was available! Does anyone know where I might find a used one or want to sell theirs?

I'm just starting out, and I don't really know anything about this, so try to bear with me. in the hookup guide, it says that this can be used to program any AVR microcontroller. how would I go about, say, programming an ATmega instead of an ATtiny? where would I get the proper definitions for the controller and stuff, and how would I hook it up? in the hookup guide, it refers to holes that are nonexistent on the actual programmer for the outputs; I assume, however, I could just work around this by plugging the jumpers into the prototyping sockets and connecting the proper MOSI, reset, etc. pins to the pins on the other chip. would this be correct? sorry for all the questions, I'm sure some or all of them are relatively stupid. if there's a tutorial for this type of thing, that would be great. I haven't been able to find one, though.

When are you guys making more of these? I want to buy one.

What is the avrdude command in linux to use this...been trying all day...

Could I use this as a icsp for any avr such as the atmega328

Would this work with the ATA6286C from Atmel? It's an AVR 8-bit micro-controller IC that integrates RF transmission and LF receiving functionality. Here is a link to its page on their website.

After trying to make an Arduino ISP programmer for an attiny and melting a breadboard (and possibly almost damaging my computer) I decided to buy one of these. I bought it several months ago and it still works great. I kept getting error messages from the Arduino program at first, but I got it to work after following the instructions at

http://webcache.googleusercontent.com/search?q=cache:HxkXceMAbiAJ:hlt.media.mit.edu/%3Fp%3D1695+&cd=1&hl=en&ct=clnk&gl=us

The MIT link with the tutorial is down, can someone help me by giving me any guidance.Thank you.

I'm trying to branch out from my Arduino and use these chips in new project an this be used to program the 14 pin ATtiny84?

Hey sparkfun, where can I get my hands on some of those headers on either side of the ic socket? (Hint, hint)

I bought this one recently from a local distributor. Works flawless when plugging Attiny85 onto the board. However, when I soldered a 3x2 ISP header and tried to program an Arduino Pro Mini, it didn't work, saying; "Double check connections and try again, or use -F to override this check" Connections are fine, checked for many times.

I connected the 3x2 ISP to straight 6 pin header on Pro-Mini in following way;

ProMini - TinyAVR

• BLK - GND
• GND - SCK
• VCC - VCC
• RX1 - MISO
• TX0 - MOSI
• GRN - RST (reset)

Is this compatible with AVR Studio?

Link to the tutorial is broken. Do you know where it can be found?

Please can anyone tell me how i can setup this tiny Avr on window 7 and what software did I need thanks

Hi,

I try to program an arduino mini pro with the header ... without success..

I receive : "avrdude: stk500_getsync(): not in sync: resp=0x00" ..

I used this configuration => http://arduino.cc/en/uploads/Hacking/image002.jpg

Any suggestion ?

In using the tiny AVR programmer to program using Arduino 1.0, I normally get the following error while trying to upload the simple blink program: avrdude: verification error, first mismatch at byte 0x0080 0x3b != 0xff avrdude: verification error; content mismatch

If the mismatch occurs at byte 0x100 or higher, the program runs. How do I resolve this problem? I have also tried Arduino 1.0.4. I am selecting UStinyISP as the programmer.

Reset and power solder pads? Really? Tom used jumper pins, so was it a conscious decision to build in obsolescence?

every time i try to install the driver, the installation stops and gives me the error "the third party INF doesnt not contain digital signature information" any ideas as to what im doing wrong?

could i use this programmer to upload the assembler file mentioned in this link: http://elm-chan.org/works/sd8p/report.html

it says it need a HVSP programmer.

Will This work on the ATtiny25?

I've had zero success getting this programmer working on OS X Lion. Mainly driver issues with the USB ports as far as I can tell - although a recently bought Arduino Uno was entirely plug-and-play on the same machine.

Also, since it seems there are many, many possibly pitfalls involved in setting up the Tiny Programmer to work with the Arduino IDE on OS X, the set of instructions and workarounds available on google is limited but overwhelmingly self-contradictory. If you want to use Arduino to program an ATTiny chip using the High-Low attiny library, I'd skip buying this board and instead buy an Uno to use as an ISP.

Sparkfun team and fellow enthusiasts, I bought about 10 ATTiny85 20PU chips off of ebay and then bought this "Tiny Programmer" to program one of these atmel chips thru it. when I upload the "blink" example (using 1 pin as the output), I get the following error at the time of upload. Any help you can provide at the soonest please. Thank you in advance

" Binary sketch size: 836 bytes (of a 8,192 byte maximum) avrdude: verification error, first mismatch at byte 0x0100 0xa0 != 0x63 avrdude: verification error; content mismatch "

Ok Just got one and I wish you used the same female headers that everything else uses. The ones on here, I think are called machine pins, and they only seem to handle 24 or so gauge wire not the standard stacking headers.

I was thinking of making kind of a shield for it I could pop on or off since I understand you can't always program it hooked up.

Like Krb686, I can't get the Tiny Programmer to work.

I followed all the instructions on how to install it on Window (32-bit), installed the drivers via Windows Device Manager, and Windows now recognizes the programmer as "LibUSB-Win32 Devices->USBtinyISP AVR Programmer".

I also am running the Arduino 1.0.3 environment, and have installed the attiny files into the Arduino\hardware\attiny folder, and the Arduino Environment shows all the different types of ATtinys under Tools->Board.

I'm tried several different brand-new ATtiny85's, but all give the following error when I try and program them:

avrdude: initialization failed, rc=-1 Double check connections and try again, or use -F to override this check.

My Arduino environment works fine programming several Arduino UNO's and Arduino Pro Mini 328's (using the FTDI Basic Breakout).

Can anyone figure out what I am doing wrong?

So I just bought this thing, got the IDE running, installed board definitions, plugged in the ATTiny85, now when I try to upload it gives: intialization failed, rc=-1 Double check connections and try again...

Great product! Installed the programmer files in Arduino and was up and running in less then 15 min. 3 ATtiny85 programmed and circuit tested in 20 min. I have earlier tested the "Arduino ISP" way. Works fine but the AVR programmer is simpler (not a lot o wires). Testcircuits can be built on the programmer.

This works fine with Arduino software 1.0 but will not work with 1.02. In 1.02 it tries to load hardwareserial.h which will not compile with attiny selected. An issue with Arduino software V1.02. Haven't tried with V1.03 yet. Also with windows 8 Pro you need to disable driver signature enforcement to install driver.

This is a novice question, but could one program an ATTINY-10 (or similarly small Atmel chips) with this programmer?

Driver doesn't want to install.

1. If you run install_*.exe it gets a "could not open pipe for writing: error code 2".

2. If you try to install via the .inf, "The inf file you selected does not support this method on installation"

3. Windows usb Plug_'n_Pray doesn't find a driver.

I tried both the x64 and x86 links and both install files in each.

Win 7 pro x64, 16 GB ram, 4.1 Ghz I7, 3 TB of SSD in raid 5 and raid 0.

EDIT: after looking at Limor's site I found the problem. My somehow when I plugged in the USBTiny the popup got squashed. The Inf won't install from anywhere other than the device manager or the USB Plug-N-Pray wizard with this package, although some documentation implies there is a differently packaged version of the drivers that will. If you have the same problem you can use the device manager tool in Control Panel to manually install the driver on the unrecognized device.

Those cheap 8-pin sockets are not rated for all that many insertion cycles, why not use something better?

I am guessing that the VCC point near the 6pin header is there to disable 5v to the ISP header pin?

I bought this after I spent 2 hours not communicating with my aatiny85, which was wired to my avr_isp2 programmer via a breadboard. Hopefully this reduces the variables of where I could have messed up! :)

You can actually use a ATtiny45 instead of ATtiny84. Cheaper, and saves a crystal (ATtiny45 has 4xPLL to generate 48MHz clock internally): http://tequals0.wordpress.com/2011/09/26/attiny45-based-usbtinyisp-programmer/

How does the onboard ATtiny84 handle USB? Looking at Atmel's website, that chip doesn't have built-in USB support.
