Hi, I’m new to these devices …and forums!
I’ve just purchased a Logomatic with a view to tweaking for a particular application. Powering it up for the first time, I suspect a problem, though would like to confirm it’s not user error. …Advice from the Sparkfun chaps would be good as I’m not even getting off the starting blocks yet.
Here goes:
Inserted 2Gb FAT (not FAT32) formatted card, applied power (pre-adjusted 5V stabilised lab. supply) and switched ON: Red USB LED lights, no other activity.
Switched off and connected USB to pc. Power up: Red USB LED & The card is recognised by pc. and is writeable. (Tried drag and drop some files)
Unplug USB whilst powered, the red USB LED goes out with no other activity.
Power off, remove card, power back up and the two adjacent LEDs come on and stay on along with USB LED. I get the impression the system is not even looking for the drive when not in USB mode. Any ideas anyone?
Thanks in advance John
