Stll waiting for the long-promised Tibbo EM500/GA1000 firmware so I'm trying to fill the time productively. The ConnectOne shield now supports 2 WiFi and 1 NoFi module.
Oh, no! Now I'm also waiting for mackrackit to decide on an EEPROM and to start coding.![]()
uhmm,
I need to quit falling asleep. I missed the part about volunteering..
I do not have a whole lot of time to dedicate to a new project as much as I want too. But I will try to find some time to play
As far as EEPROMs... FRAM seems kind of expensive. Not sure how big of one would be needed, maybe a 24FC1025 would be "OK" ? After it is all setup should be just READS....
Need to sleep on it some more![]()

Always wear safety glasses while programming.
I already have board designs for a battery backed RTC and for an EEPROM. Both are I2C and they might be plugins on shields that should require one or the other. I use 64KB in another application so it would be simplest to just use it, as is. Or, it might be best to just provide for a DIP that the user could add.
I'm also kicking around my own design for a slightly more costly but much easier and much more powerful Arduino clone that would make a great test bed and development system It's all this time on my idle hands...![]()
I think I can forget about seeing the Tibbo firmware anytime soon so here is what I think is the final layout for the ConnectOne ethernet shield. The TX, RX connections are dictated by the PICAXE and Xino. I still need to check this with the Xino designer but I think it's ready to have CircuitMart make some prototype PCBs.

When the Tibbo firmware is released I hope someone will consult a medium and let me know.
I'm going to spend my time finalizing the design of yet another Arduino clone. This will use a ZBasic ZX328n but it will be socketed so it can be replaced with a AVR Mega328P.
When my Xino kit arrives I'll see whether it is practical to modify to use the comparators as inverters for TX, RX. That should work with 16F88, 16F886/887 and 18P25K20/22, lowering the chip count.
