I do not dispute htat. My main comment was to the
poster who suggested an
ARM-based microocntroller (I have never seen seen such a device in a DIL
package)
There are always SMD to DIP adapters :)
- I can
design a PCB at home using free tools (Kicad rulez!)
For the nth time, the machien
it runs on (and I susepct the OS it runs
under) are not free.
A Pentium III - which you can find in trashcans - runs it with linux.
And linux is free :)
Excellent (I am not being sarcastic). Hwoever,
building that equipment is
a project in itself (albeit an interesting one). If you just want to make
up a SCSI-drive rpelacement or whatever, why should you _have_ to make
the PCB stuff first?
I can always use perfoboard...or just connect the wires chip-to-chip.
Why? As I said in anotehr message, thsi is a hobby,
why shouldn't I do it
the way I enjoy?
You can do in any way you want :) But when I do and for people being
able to reproduce it, I try to do it in the easiest way to most hobbists to
reproduce it. :)
Fine. I was ismpoly pointing out that there are people
who ar
expeerienced in (say) Z80 assemblet and not AVR. In which case, for a
hobby project, why not use the former?
No problem. But why not use the later, since it is more powerful, has
more built-in things and is easier to program (not everyone has an eprom
programmer, emulator, eraser, etc) for most hobbysts
Looking around, I don;t think I can see _one_ machine
here that could be
used for that. You mention a programmer conissiting of a few resistors
You don't have ONE PC on your home?
ona a parellel port. I've got pletny of GPIB
ports here, but I guess
that's not what you meant. OK, what about an HP9817 with an HP98522 GPIO
card? It probably could program an Atmel processor, but I'll bet the
software doesn't exist...
The nice thing of open standards is that you can always roll your own :)
OK, so firtly you have to buy this tool [1] and
secondly I need a USB
host to control it.
Ah, come on Tony, P3 are throwaway itens...P4 are cheap as candy. A nice
post "I need a P4"will bring 3 or 4 to your door. For free. Why not use new
technology? Linux drives that, you don't need to use windows. And if you get
a PC with ORIGINAL windows installed, you can have it for free.
I'd much rather know what my hardware is actually
doing than what some
simulator things it's doing. The fewer uncertainties the better!
I programmed a nice debugging monitor for the AVR, so I can see
everything is going on :) I used that before having the hardware debugger
6303 in one of its many varieants? 7811? COP400? 3870?
Do I have to list
any more?
Was ist common?? When?
Actually I disagree with that. It's often easier
to repari something with
lots of parts, where yoy only have to replace the one bit that's failed.
Which would you rather have to fix? An HP9830 (lots of TTL), a Sinclear
Spectrum (custom ULA) or a modern PC motherboard.
I can repair the three :) I can even recreate the speccy ULA in CPLD :)
