Jumpers set for parallel programming of ATmega328P There are some clever alternative possibilities, though.
The disadvantage of this approach is that changing jumper configuration is somewhat time-consuming and potentially error-prone. The image to the right (from the Atmel website) shows the end result: This lets me use the Dragon for any supported combination of target and programming mode, merely by adding jumpers in the right place. My choice, with which I’ve had good results, is to add pin headers to the HV Prog connector area and the adjacent 40-pin “EXPAND” connector, then add a 40pin ZIF socket in the prototyping area. They give you a flexible prototyping area and a place where you can solder headers. The Dragon does not arrive ready for use. The “avrdude” utility supports most of the Dragon modes, too. It supports the same six-wire ISP as most of the cheap options. parallel programming, so you can “unbrick” chips with mis-set fuse bits.emulation support for devices with 32KB flash or less.debugWIRE and JTAG support for in-circuit debugging.
#Atmel dragon board serial
high-voltage serial programming, so you can program low-pin-count AVR chips.Here are some of the features that set it apart from other low-end programmers: However, the Dragon gives you a lot of flexibility for not much more money - if you’re willing to put up with some extra hassle. If you’re averse to soldering, one of the Arduino variants (with on-board programming hardware) may be of more use. If you’re just starting out, there are cheaper options that work well (like the USBtinyISP from Lady Ada). There are lots of AVR programmers out there. The specific application I’m going to talk about here is using it to “fix” parts when you’ve set the fuses in such a way that said parts won’t talk to simpler programmers. It’s relatively cheap (around US$50 at the time of this writing) and does many useful things. The AVR Dragon is a gizmo made by Atmel, useful for programming their AVR line of microcontrollers. This post isn’t about the usual kind of dragon (if there even is a “usual” kind).
