Awesome idea. I want to try this. But do they exist in Micro SD sizes? I can't seem to find any.
Not that I've found - but the LCD has a standard SD socket. You need an extra lead to connect it to the Duet.
Keep the lead short - much over a foot and it doesn't work. Mine (after some re-jigging) is 6" long and works pretty good.
David, I thought it was the SD initially - but I'm on card No 4 now and it's the same. That's why I wired up the SD socket in the PanelDue - but found it wasn't supported in the web interface for file upload due to speed considerations (ironically). The previous Micro-sd's seem to work fine in the PC speed wise.
When you first start uploading, it runs at 1-2Mb/s then rapidly slows down to a crawl - almost as if it's filling up a buffer then slowing when it's full?
Were it not for that, I would assume it's a signal strength issue - but it it can achieve fast transfer at the start, I suspect it could continue.
With the WiFi SD plugged in to the PanelDue it's OK.
