Pointers for Atmel AVR uses?

[jksuperstar]

I started off using the stimulators myself, but found it much easier to just connect the switch on a breadboard, and make an LED blink. Once I had the basics proven, I started learning about the device more quickly by just doing it, and keeping my momentum (& excitement) going, rather than simulating things & stepping through all the code.

BTW - there is a free simulator that is included with WinAVR (simulavrxx) that one can use if you wanted to step through code just to see it.

Cool. I was only really interested in AVRstudio for the sim. (and I'm programming the chips via it too at the moment) so that's good if there's a WinAVR (simple) sim.

Thanks!

I now need to get going again 'cos I made the proto sequencer block - haven't tied it to the AVR dev. yet but its working as a block (four stages with a global range dial (c.1v range to 5v range) and glide ----- nice!)

I can see the value in that. Especially if you're coding in assembly.

I was thinking of building this

myself I know nothing about avr/microcontrollers, but a guy I know
has the equipment/skills for programming it, but he says that he needs
the data in hexfile format, so I was wondering if someone here could help me to convert this

http://www.borg.com/%7Ejglatt/hardware/pc_keys/pckb.asm

into hex format, I guess you need some kind of software to do this ?

[blue hell]

Yes, you need an assembler to translate the assembly code into numbers that can be understood by the processor. The numbers can be put into a hex file and in that format most programmers can burn them into a chip. Usually one of the output file formats for an assembler for a processor like the AVR is hex.

I don't use AVR myself, but a quick google showed that Atmel has a development environment that seems to be down loadable (after registration) - that one should do the trick ( http://www.atmel.com/dyn/products/tools_card.asp?tool_id=2725 )

Another option would be to have a look at http://sourceforge.net/projects/avra

But probably AVR diehards have better suggestions for tools.

You should consider making your own development environment , as software is never bug free and if it were you still might want to modify it.

The AVR chip used in the link features in circuit programming, which makes it possible to program the device while it is in the circuit with relativley simple and cheap (serial, parallel or USB) interfaces (from your computer). This will enable you to modify the program and beam it up to the controller immediately.

The interface might even allow you to single step through your code to help you see where things go wrong - I'd be disappoited if it wouldn't allow for that

thanks for your reply BH,

a person who is into this kind of software has now helped me out


cheers,
