Started with the demo@ http://spinneret.servebeer.com:5000/
Looking at the Spinneret Web Server code, I'm trying to figure out what to do about the RTC since I have none. I've though about using one of the RTC emulators or possibly just disable them? Any advice from the experts would be greatly appreciated.
Also plan on using in SPI mode. I see that the driver is not directly compatable with Indirect Addressing object??

The new stuff, which I suggest, is also located in Google code
Checkout the Html5Graph.spin, that's a pretty good demo. Really, the only things you need to do is make sure the IO (hardware/software) is configured correctly or as expected.
Also, the later does not require an RTC. However, in both cases, if using the FAT engine, the RTC driver can be turned off in the FatEngineWrapper by entering a -1 for the I2C arguments in the start method.
Mike- I checked out this site but don't find anything to download.
I'll have a bunch more questions soon, still need to play with this a bit more.
Huge thanks for the quick response guys

PUB ReStart spi.ReStart PUB Stop spi.StopI'm not a fan of ReStart logic in Read and Write Methods. It works but I'd rather explicitly invoke Start and ReStart.
I'm not sure about the OR gate mentioned. Please post a schematic.
A hardware reset can take up to 1.5 seconds to take affect. Registers R/W will function while socket commands may not. That's been my experience.
Google code has been updated with the latest. The socket library and W5100 can better handle large file downloads. I did not add the ReStart logic to Google code.
