I love how I can see the HTML being streamed onto the page in real time, like the good old days of dialup when images gradually rendered from top-to-bottom.
Brings memories. How my school trashy dial-up was so unbearably slow compared to my father's work 128 ISDN.
On latter, I was able to even download several songs per visit from ftp, and later from Napster.
The PIC32 CM has most of the features of AVR DD, including event system, MVIO, 5V operation... while offering a larger and standard ARM 32 bit M0+ core.
I fear the AVR DD is somewhat obsolete with this. AVR EA and AVR EB and their 12-bit ADC with x16 programmable gain (sensitive to 50 microvolts or so, albeit with a fair bit of noise), remains safe as that's an absurdly good ADC / current sensor.
Or alternatively, maybe this will make AVR and friends more popular? Does the knowledge of a pin compatible (??!?!?!) ARM32 Cortex M0+ make you more, or less, likely to build a top the AVR platform?
IMO, it's the peripherals that matter most. AVR DD likely offers lower power consumption (especially the 1.8V operation), but is that enough?
---------
Otherwise, very intriguing project. AVR DD is an excellent chip in any case, great to see people using it in practice.
> The obvious choice is Ethernet, but even the slowest version (10BASE-T) still runs at 10 megabits/second. Worse, it uses Manchester encoding: a zero is sent as "10" and a one as "01", so 10 megabits of data is actually 20 megabits at the wire.
Note that the AVR EB has a x2 PLL timer that probably can output manchester encoding if you spent a long time playing with it?
Maybe?
Hmmmm.
Between the LUTs, UART peripheral and PLL boosted timer circuits, it's probably possible to push out high speed manchester encoding.
Maybe not 20Mbit though. I'll have to think of it.
Firstly: There's a 2025 (sic!) erratum to RFC 1055 that isn't in the www.c here. The erratum (q.v.) makes a good case for how it changes the decoding algorithm, and it actually is Linux on the other end of the link in this case.
Great project!
I did one on arduino mega a while ago. Amazing how good it can look since client does a lot of heavy lifting. Controller merely delivers content from uSD card...

Secondly: Next stop RFC 1144, presumably.

Someone with an ACE1101 microcontroller "won". I can't find the original articles, but there is also this:
