Hi guys,

I was able to bring up the WiShield webserver examples on the maple last night. I'm busy tonight but I'll clean up the changes I made this weekend and post a repo link for you guys.

In order to avoid the 3.3V problem, I bent the 5v pin on the shield back a little bit so it wouldn't go into the female header on the maple, then put in a jumper wire from Vin on the maple (5v if powered off USB) to the 5v pin on the shield. It seems to work fine.

I haven't tested or ported the dataflash library yet.

here's a dev branch i've been using:
http://github.com/iperry/maple-library/ ... shield-dev

It should bring up the webserver example from the asynclabs guys, see main.cpp for the 'sketch.'

it's a very rough port, but I need the wishield for a project I'm working on and this suffices for now. let me know if you guys have any problems.

This works for me on an unmodified WiShield. The 3.3v voltage regulator supplies 3.3v to the ZG2100 chipset fine even when the input voltage is 3.3v, like the Maple has.

Here's picture:

The above post has short instructions on checking out and building from Perry's repo.

Hello, I tried to get the port from github but it seems like the project was deleted. Does somebody have the lastest source code?

Thx
