[Coco] IP packets on my coco

[Mark Marlette]

Aaron,


All of the development I am currently doing is based upon using Drivewire commands to/from the host. The host can be a PC(the original DriveWire sense), an Atmel AVR(as in my case) or a DEx(as in Gary's case). Using existing commands, if present, if not creating my own.

It is then the responsibility of the host to perform the low level functions to get the jobs done. Apps written this way can careless what the base hardware actually is. It talks at a higher command level and the host performs all the low level functions and all low level / high level conversions.
This is the basis as well for the MP3/WAV sound processing, Ethernet, Bluetooth and WiFi development currently going on at Cloud-9.

Spoke briefly on this at the fest this past year, could spend a whole seminar on this alone. Routines for DNS, NO-IP client, Ping, SMTP, SNTP, UDP, WhatsMyIP are some of the current low level routines already functioning. These are on the Wiznet platform, eight sockets currently available. Off loading this to another device, to free up the CoCo to process other tasks.

Not wishing to hijack Brett's original thread.......

I've been wishing for something like this to be connected to a coco for a
long time.  In fact when I learned about these things is when I kind of
lost interest in further DriveWire work... this is just a better solution
imho.

Then while exploring gary's (amazing) work with coco3 fpga, I thought: hey,
now we can connect one of those network stack in a chip things real easily
since the de1 can talk to them.   I talked with Gary and some other
coconuts about this, and as I recall everyone thought compatibility with
'real' cocos was a major concern.  In a small community, it helps everybody
have fun when projects inter-operate.

If you can get the same controller attached to a real coco and the DEx
boards, that's a standard that lots of different projects could use to do a
lot of cool stuff.  Seems worth doing to me.  Have you thought about ways
to avoid being tied to a single controller, or if that matters?

Sounds awesome.  And also major kudos to Brett for the nice work on Fuzix

would be difficult with the ESP8266 as it stands now. The fact of the
matter is, if you use the ESP8266 for a DECB program it will be more than
adequate as you won't be doing any multi-tasking where other programs would
need to access it at the same time.  If you wanted to use it under NitrOS9
which could also require that you write a device driver for it, then you
may have a problem running multiple programs simultaneously that would be
using the internet.
