SOLVED - Wiz820io Problems
Hi
I have ordered a couple Wiz820io adapters on ebay and not having much luck getting them to work. I managed to get one working occasionally but the link and activity light will sometime lite up and every once in a while I can get a test ethernet web server sketch to work. But not consistently. If I re-seat the module and try differnet USB ports It will ocassionaly run again. When it does work I managed to test it out with some dmx stuff and I could see that it was processing the packets and reporting RGB values as expected, however it was laggy and the responses were delayed consistent with the LED on pin 13 when it went solid during the fractional lag/freeze.
The second module is non responsive at all. It only links and shows activity but there seems to be no SPI intelligence.
The buyer I got it from did have a negative comment about his wiz adapters being "Junk", So I question if I have good ones to begin with.
Any suggestions on what I should test out? Is it ok to run both teensy and wiz module from USB power? (wiz module positive pins are on 3.3v pin on teensy)
My Wiring is just like this post (https://forum.pjrc.com/attachment.php?attachmentid=1758&d=1396193449) . The wiring should be right due to that I have got it to work on one module occasionally.
