Here’s a new option for building your own AVR programmer. It’s called and the diminutive size makes it live up to its name. The design is rather spartan, using just three chips; a voltage regulator, a MAX3002 level converter, and an Atmel AT90USB162 as the main microcontroller. This chip has a built-in USB module, foregoing the need for a separate FTDI chip. The firmware is built on the (LUFA).

This is a USB stack implementation originally called MyUSB that was developed by [Dean Camera]. Regular lurkers over at the AVRfreaks forums will recognize [Dean’s] name, or his handle [abcminiuser] as a source for many of the high quality AVR tutorials found there. But we digress. The programmer offers all the features you’d want in an In-System Programmer. It can easily be reflashed with future updates thanks to the bootloader running on the chip. There’s jumper-selectable power options, and it can program targets running at 3.3V or 5v. The full development package including code and artwork is available for download at the site linked above.

For your convenience we’ve embedded the schematic after the break. Posted in Tagged,,,,,, Post navigation.

Two notable differences: 1) The USBtinyISP implements its USB interface by bit-banging i/o pins on a non-USB AVR. This is generally reputed to work, but could theoretically be unreliable under certain conditions. The AT90USB162 in the MkII Slim has a real hardware USB interface. 2) The USBtinyISP is a product that you can buy in kit form.

Ergo's Unofficial Patch is a very old mod for Drakensang RoT, unfortunately worked on an old version of the game. Now the game is patched with a Not everything's in English, there's a lot of German in the Drakensang files. Tinder Fungus = Zunderschwamm, and Throwing = TaWurfwaffen, etc. My English version of Drakensang is 1.03 and my German version 1.11. Does anybody happen to know if patch 1.11 has ever been released in English or is thio patch only available in German? Nobody english version lyrics.

If you want a MkII Slim, it looks like you’ll need to build it yourself! For your second question, the MKii Slim is a clone of Atmel’s AVRISP mkII programmer: As noted, it is compatible with AVR Studio.

In windows 8, OHC was working properly but when I upgraded to windows 8.1, there is a driver problem. I can't update driver, can you tell me a way to install drivers for LUFA avrisp mkii clone.

Unfortunately not, because Atmel’s DebugWire protocol is proprietary and undisclosed. And while the Dragon is only $50, you get what you pay for: combined with avrdude and avarice it’s unreliable and irritating to develop with – single stepping alone can take 3 seconds per instruction. I usually have to unplug and re-plug my Dragon more than 10 times a day when developing for AVR, just to reboot it:-( If you want real debugging, use an ARM Cortex-M0/M3 – ARM publishes all the debugging specifications and both SWD hardware interfaces and software debuggers are widely available. As for this build, including ISP, PDI /and/ TPI is excellent! It wasn’t that long ago that I had to bit-bang TPI myself to program an (unsupported) ‘tiny10 chip. If you want to debug, you need a JTAG capable device.

Save your pennies and get a JTAGICEmkii-CN from MCUZone in China (I have one and it’s under US$100 delivered and nifty as hell) or a cheaper AVR-JTAG-USB from Olimex – either will work well in AVRStudio4. Programmers like this are simply for reading or writing the flash memory and EEPROM. That’s great if you’re into large production of Atmel based boards or need to do in-field reprogramming but of dubious value to the solo hacker and developer. Hey, you need to download the full latest LUFA package and unpack it.

When that’s done, you need to set up all the dependencies than are needed to compile the LUFA projects.

AVRISP-MKII Clone (2010) After first creating my LUFA USB stack for the USB AVRs, I decided as a side project to create a new firmware for the entire USB AVR range, which would emulate an AVRISP-MKII. This project is a clean-room copy of the AVRISP-MKII functionality, supporting the programming of the entire 8-bit AVR range via ISP as well as the PDI (for the newer XMEGA AVRs) and TPI (for the 6-pin TINY AVRs). It is entirely open source and has a wide range of configuration options to adjust the feature set and pin-out.

One example of a programmer using the clone firmware () When compiled for the XPLAIN board target, the code will automatically function as a PDI programmer for the XPLAIN board using the optimal settings. This will allow the XPLAIN board to be programmed from within AVRStudio without additional hardware. • ISP, PDI and TPI protocols supported • 4MHz ISP Rescue Clock (for incorrectly set system clock fuses) • Fast, native USB operation • Works on any USB AVR model • Works with anything the official AVRISP-MKII works with (e.g. AVRStudio 4.x and 5.x, Atmel Studio 6.x) Special thanks to, who has been instrumental in testing new code revisions to ensure correct operation.

For device pin-out information, build the Doxygen documentation from the source by executing 'make doxygen'. The resulting documentation will be located in the /Documentation/html/ directory of the source folder. Downloads • See Projects/AVRISP-MKII folder of.
