Hi,
Likely you think of IP65 as an asm written TCP/IP library for asm
programmers. But IP65 has significantly changed recently in two
directions:
1. C Interface
The IP65 programming model has deliberately always favoured simplicity
over flexibility. However, targeting only asm programmers there
weren't too many to appreciate that design.
Since I started to maintain IP65 I worked on making IP65 usable for C
programmers and recently that effort was completed successfully. You
can now download ready-made libraries plus a C header file and start
your own TCP/IP or Internet program right away using cc65.
The approach to call asm code from C is totally natural to cc65 given
that the C standard library is written almost completely in asm too.
And just like the C standard library IP65 can be used on several 6502
machines. All this fits so nicely that I adopted IP65 as part of the
cc65 GitHub project, meaning the IP65 main URL is now:
https://github.com/cc65/ip65
If you want to take a peek at the IP65 C interface check out
https://github.com/cc65/ip65/blob/master/inc/ip65.h
2. Ready-to-run TCP/IP programs
Beside the libraries IP65 now comes with five programs:
https://github.com/cc65/ip65/wiki/Ready-to-run-TCP_IP-progra ms
- Telnet65 is the only asm program coming with IP65. I completed it
already 1.5 years ago.
- Date65 is primarily a demo for a simple IP65 C program. Additionally
it can be of actual use for everybody without a real-time clock.
- HFS65 is an HTTP file server allowing any web browser to access all
files on an Apple II.
- Wget65 is an HTTP file/disk downloader with advanced cmdline like
UI. I created two demo videos.
- Tweet65 is primarily a demo for triggering events on IFTTT aka
if-this-then-that (https://ifttt.com/) from a 6502 machine.
Additionally it can be used as-is to post tweets on Twitter after
putting together a simple "Applet" on IFTTT.
Have fun with all the new possibilities! And this time round nobody
can complain that there are no Ethernet cards obtainable ;-)
Regards,
Oliver

Hi Jeff,

:-)
> What would it take to read a twitter feed with IP65? Possible?
Obviously I thought about that too...
Short answer:
No.
Long answer:
- IFTTT is about events, things that happen, data that is pushed. So
there's no idea to pull the tweets from your feed. Rather you can only
define events like "There's a new tweet matching some serach
criteria".
- If such an event occurs then IFTTT can call a webhook. But that
requires your home router to forward incoming TCP traffic on some port
to some LAN machine.
- Such a webhook call would be SSL/TLS encrypted -> showstopper.
- Currently IP65 doesn't allow to both listen for incoming TCP
connections and establish outgoing TCP connections.

Oliver

Anything is possible. But unless you or somebody you love writes an SSL for
Apple II, you'll need to use an HTTP proxy. Then you could use the W5100's
built-in TCP to send an HTTP request, or you could use Contiki's web
browser.

Thanks for trying - and the feedback :-)

I was trying to find out if the keys have a fixed/maximum length. It
seemed to me that they have (with 22 chars). However my thought was
obviously very wrong :-(
I just updated Tweet65 to allow for up to 80 chars.

Hi,

This statement turned out to be wrong. In fact IFTTT allows to define
both https:// and http:// URLs for outgoing webhook calls.
With that it becomes an option to receive IFTTT webhook calls with an
Apple II using IP65. In order to prove that it actually works I
created a (pretty silly) demo that allows to use the Alexa commands
- Alexa, trigger black
- Alexa, trigger orange
- Alexa, trigger green
- Alexa, trigger blue
- Alexa, trigger white
to have an Apple II fill its screen with that color.
I personally find it amazing how little code is necessary to do so.
Find it at https://github.com/cc65/ip65/wiki/IFTTT and the demo video
at https://youtu.be/IO0twDOMDlQ
More interesting usecases would be some personal digital signage
and/or Iot / home automation using the Apple II Annunciators.
However, it holds true that IP65 doesn't allow to simultaneously
trigger and receive IFTTT webhooks. Rather the user needs to press a
key to stop the webhook reception once started.
And finally, IP65 only supports HTTP GET requests (without body). It
has built-in support for query string parsing. The URL can be up to
$800 bytes.
Have fun building something cool with this,
Oliver
