Just a quick post that I’d would be good to mention – If you’re like me and still using WinAVR 20100110, you’ll know it hasn’t been updated for a long time, but what if you want support for the new MCUs like the ATtiny1634? It’s quite simple, just follow the steps below.

  1. Download AVRStudio 6 and AVRDude MinGW32 6.1 (at the time of this post)
  2. Backup your C:\WinAVR-20100110
  3. Delete all folders in C:\WinAVR-20100110 except for the folders pn and utils
  4. Copy all the subfolders found in C:\Program Files\Atmel\Atmel Studio 6.0\extensions\Atmel\AVRGCC\\AVRToolchain to C:\WinAVR-20100110
  5. Extract the two files from the AVRDude zip file to C:\WinAVR-20100110\bin
  6. Download this avrdude.conf file and replace the one in C:\WinAVR-20100110\bin (otherwise you will have issues programming the ATtiny1634, fix was taken from this post)


Looks good, here’s the ATtiny1634_Test program I’m using to blink the LED with the watchdog timer.

    Hi there,

    Just a quick note to tell you that the website RSS feeds resends articles at each poll, making RSS reading a bit boring 🙁 Could you modify your RSS generator so that it does not change articles date and keep artlcles publish/update date ?

      Hi, which RSS reader are you using?

      When I load the RSS feed directly from Chrome I see:
      Tue, 27 May 2014 12:49:49 +0000

      And for this post it’s: Tue, 27 May 2014 12:49:49 +0000

    I am using NetNewsWire 4.x beta. The RSS feed being used is at http://www.insidegadgets.com/feed/. It seems that NNW does not appreciate something. At the moment, the last displayed entry is “Playing around with the Cypress CY22150 Programmable Clock Generator” even if the RSS feed shows newer items. There’s something strange 🙂

  3. I’ve got AVR Studio 6.2 and the toolchain seems to be at:
    C:\Program Files (x86)\Atmel\Atmel Toolchain\AVR8 GCC\Native\3.4.1056\avr8-gnu-toolchain\

    It looks like the license of this (according to the file in that folder) is GPL so I assume that one can use, copy and distribute it without any limitations. Any thoughts?

    • Alex says:

      I don’t think there should be any issues if it’s GPL. Even if it wasn’t GPL as long as you didn’t re-distribute it or packed it into your own software and distributed your software, you’d be fine.
