Very nice. Just a note: It is not in the library USB_Host_Shield_2.0 but MAX3421E supports suspend signalling. CGMS receiver supports suspend signaling. In USB suspend mode CGMS should draw very low current.
Deciphering that USB code is beyond my talents. IF that could be done, and the Dexcom didn't "wake up" each time (ie. activate the display), this could be a low power solution. I did this by turning on the usb power every 5 minutes, but it required restarting the micro, and it drains the Dexcom battery.
Very nice.

DeleteThanks for putting this up! You actually sent me a good bit of code the other day and I think I'm getting there with my rfduino! Thanks a ton!
ReplyDeleteGreat, I think there's more than a few people that would like a port for the circuits@home usb to rfduino.
DeleteThank you very much for your work, I'm really interested in your progress.
ReplyDeletePlease tell us more details.
