FWIW, FPGAs do something similar -- they can literally reconfigure their *hardware* while running, if designed properly. Pretty cool stuff. This would open students' worlds into this concept.

Re: Base sketch won't upload
That's really odd... I've programmed many AVR uCs, and avrdude usually works, provided that the fuses didn't get horked up somehow. (Then you HAVE to do an ISP connection, or worse, a dedicated chip programmer). Just so we can be sure we're not missing something that seems obvious to you, but isn't ...

Bastian: See this thread: http://forum.plumgeek.com/viewtopic.php?f=18&t=7897 But the bottom line is I got it work with the Arduino IDE, with these settings in the pull-down menus: Board: "Arduino Pro or Pro Mini" Processor: "ATMega328 (3.3V, 8Hz)" Programmer: "ArduinoIS...

Re: Spirit Pi configuration: virtualenv -- necessary?
To quote Bastian: Since it's not that easy to replace the micro-sd card of spirit... Already done it. Twice. Once to start from scratch with a Raspbian stretch version from RasPi (dated 11-29-17) instead of jessie, and another time to fix something dumb I did in the /boot/ partition. Tweezers are yo...

Re: Spirit Pi configuration: virtualenv -- necessary?
Any python module that *depends* on executing in virtualenv is dubious... I'm a bit leary of using that one.
What package is that? I'd love to take a look at it, I might be able to decouple the two...

Spirit Pi configuration: virtualenv -- necessary?
Is virtualenv really necessary? It seems like a nice way to swap between python configurations between projects, but for an embedded system, it would seem like it's one less layer of abstraction/confusion for less savvy users. I've got my Spirit Rover configured without it... but I'm wondering why y...

Re: Pi data to Arduino via SPI
Again, seconded. Being able to program the Arduino from the on-board PI via SPI would be awesome. That way we could treat the Pi as a development workstation when needed -- no external computer necessary, if you plug in an HDMI cable and have a bluetooth keyboard/mouse configured to use with the Pi....

Re: part specs?
Seconded. Should be in an appendix to documentation. Spec sheets and manufacturer's docs are the engineer's "foundation" of information for a design, even when using something they didn't build.

Re: Democode errors
I'm debugging the same problem. I hope to figure it out this weekend.

Re: Digging the power features!
Yeah, they're pretty nice. Now that I can program the AVR directly, I'm starting to play with them, too. You can really tell when the camera is on (in this case, reading 640x480 @ 30fps, streaming to the windowing system). See my blogpost with the plot of the power time series... when the camera is ...
