I'm guessing his output is in AVR assembler. If so, I am interested in such a program. Zack On Thu, 10 Jul 2008, majid_pow wrote: > hi > > you mean it can reads the hex file and turns it to a high-level > language(like basic or c)? > >

I've written an interactive disassembler for the AVR. It allows you to open a hex file, disassemble it, add comments and labels on the fly, save intermediate work, and then produces a listing which can be edited and re-assembled. Is there an market for this? Ray

How does the AVR (say atmega16) know the difference if it is going to get programmed or if it is going to run the user program? Are there any tricks so that avoid stimulating the pins with chips I attach to the AVT thus confusing the AVR into what it is supposed to do at power up

John, Thanks for the heads up on the limited support list for that build your own jtag clone. It's looking that I should just go DRAGON for being the most complete solution. For the hardware bootloader, I'm a bit confused. Now, FLIP works on the principle that there is a HWB pin

Thanks for your response. Is it right to say that to program and to debug on the same group of pins, the only choice is the JTAG port? Are the folllowing generilzations true? All AVRs have ICSP Some AVRs have HWD Some AVRs have JTAG Not all AVRs have built in harware bootloaders

If you are building a push-pull, H-bridge style driver, look up "shoot through." That is when you turn the high side off, and the low side on, or vice-versa. The drivers don't turn off instantly, so you need a little delay. Without it, you effectively short out the power supply e

The Micrel 5014 costs all of $2.05 (smt) or $2.48 (dip), qty 1, at Digi-Key. It can be used high-side or low-side. I have only used low-side to date, figure 2 of the data sheet. The only other component needed is the usual bypass capacitor. It doesn't get much cheaper or easier.

The external WDT can easily be used to set off an external alarm if the controller gets too pooped to participate. It can also be used to turn on another controller whose job it would be to set off an alarm and shut down the system in a reasonable manner to a safe state. David Ke

In my case, it is required. The fear is that if the micro dies in such a way that the watchdog doesn't work either you'd be in trouble, so you have an external watchdog which does the reset. You also have some other way of detecting a dead micro and then arrange to fail in a "goo
