Replacement cables cost an unashamedly high amount (€20!). The 10-pin 50-mil side is the somewhat exotic connector for the Atmel-ICE, the 6-pin 100-mil side fits on standard ISP header. The Basic variant consists of the programmer shown above in the white case, a USB cable and an adapter cable from 10-pin 50-mil to 6-pin 100-mil (marked in red in the picture below). The Atmel-ICE is available in three different kits: This is shown very clearly in the user guide to the AVR Dragon schematically. Now, depending on the method and MCU type, you have to connect the JTAG, ISP or HVSP pins to the pins of the pin header connected to the ZIF socket. The MCUs is aligned according to the numbering printed at the pin header on the Dragon. Wiring for on-board programmingįor on-board programming, the M C U is fixed in the ZIF socket.

No further driver installation was necessary.

On my Windows 10 system, the Dragon was easily detected and could be selected directly in Atmel Studio 7.

Like the other programmers, the Dragon is connected to the PC via USB. However, I have noticed that the spacers are stuck even without nuts (see next photo). Unfortunately, the ZIF socket covers the holes so that the nuts no longer fit.
As you can see in the pictures, I had screwed on a few polyamide spacers in the raw state, so that the board would not rest directly with its solder joints. So it’s above all the accessibility and flexibility in the selection of extensions that make a case for the Dragon not really useful. The Dragon “raw” and with pin headers and ZIF socket If you want to use HVSP, you also have to solder a 2 x 10 pin header. With the pin header you have the choice between “male” and “female”, most of which probably take “male”. In order to be able to do the on-board programming, you have to solder a socket for the MCUs and a pin header (2 x 20) for access to the socket next to it. This has the advantage that you don’t have to build a circuit on an external board, if you just want to change a few settings, for example. The Dragon offers the possibility to program MCUs directly in its on-board prototyping area. And then you might be surprised you don’t even get a case for your money and that the part is also “unfinished” in a way. For the Dragon you have to pay about 50-80 Euros. The AVR Dragon is my personal favorite as it masters ISP, JTAG, debugWire and HVSP, and thus it uses the possibilities of Atmel Studio to the highest degree. You have, so to speak, locked out yourself and this is the saving locksmith. “Messed up fuses” means that you have chosen fuse bit settings that no longer allow programming. With this method, MCUs with messed fuses can also be restored. The term “high voltage” is perhaps a bit misleading, it’s about 12 volts. Debugging is basically possible via both ISP and JTAG, but the programmer has to support this. You can run programs step by step, set breakpoints and track variables. Not every MCU is capable of JTAG.ĭebugWire: as the term suggests, debugging is possible with this method. JTAG: A standard of Joint Test Action Group for programming MCUs. The ISP connectors are usually identical to the SPI connectors. The name is due to the fact that the programming takes place in the installed state. This is the standard method for programming microcontrollers.
First of all, however, a few definitions. I hope that my post will help you answer this question. Which programmer should I buy?Īs is so often the case, good questions and answers depend on the budget, personal taste and the individual functionality required.
#ATMEL DRAGON PINOUT HOW TO#
In separate posts, I’ll give an introduction to Atmel Studio 7 and show how to integrate and debug Arduino sketches including libraries in Atmel Studio. These are the representatives shown in the picture above: AVR Dragon, Atmel-ICE and the USB ISP programmer from Tremex / Diamex. I will only describe programmers that I own and have tried myself.

The good news is that there are quite a few of them, the bad news is that the programmers are quite expensive, especially if you want to use features like debugging or HVSP (High Voltage Serial Programming). If you want to work with Atmel Studio (renamed to Microchip Studio in 2020), you first need a suitable programmer to upload your programs from the PC to the microcontroller (MCU).
