Indeed it does, and I gingerly dangled stiff jumper wires in to program it rather than solder in headers, which seems to have worked. Here I've got it "booted up" with the Bus Pirate.

I got two of these as a result of your work, since they're almost as cheap as straight LCDs anyway. Unfortunately, I'm having trouble determining the actual pinout for the ICSP pins.

My suggestion, which has probably already come up:

Yes, that seems to be the forth (and least popular) choice in the poll.


But the options are flawed. Option 4 implies that the entire karma system get thrown out, while what I'm suggesting keeps it around and adds what I believe to be necessary improvements.

year, i guess i could put 2 longs together and deal with it that way, but i would still really like to figure out how ardupilot does it?

My suggestion, which has probably already come up: if someone gives karma, a short message (100 characters perhaps?) must be attached to the post in question, along with what rating that person gave. In theory, this lets the person being rated know why they got that rating, and it gives incentive to rate someone with confidence rather than whenever they feel like it.

You've already made this same thread twice.

It has happened to me a few times. Simply rebooting the MCU itself should work, by pressing the restart button for example.

atol() and kin cannot take String. They need null-terminated character strings.

None of those environment variables seem to be set:
None of those variables should be set normally; the makefile sets them, and they basically are only set while make is running (i.e. during the build process).

Incidentally, I have a library for this chip which, among other things, lets you twiddle with the SQW pin registers, if you were basically looking for a fairly stable reference.
11  Using Arduino / Storage / Re: Problems accessing parallel SRAM on: February 01, 2011, 09:08:26 am
It's entirely possible to drive parallel chips with shift registers, but on MCUs with SPI/I2C hardware (or software) it's not as practical since SRAM chips are also manufactured with built-in SPI/I2C hardware.

The function is called from loop():
Forward('A', 2500);
Am I the only person that saw this?
13  Using Arduino / Programming Questions / Re: I'm sure I'm Missing Something Simple... on: January 31, 2011, 09:17:38 pm
In the prototype for Forward:
void Forward(char Motor, int SpinTime)
If it wasn't declared, it would be a syntax error.
14  Development / Other Software Development / Re: DS3231 Function Library on: January 31, 2011, 08:24:30 am
The library is fairly complete, and I've fixed all the bugs I've found so far. I can upload the library wherever it should go. The archive can also include Doxygen-generated documentation (the header is marked up for this). What's left to add would be alarms, which I'll be able to add in the coming days.
15  Development / Suggestions for the Arduino Project / Re: Better idea for SMT Uno on: January 29, 2011, 06:14:00 am
So you're really talking an adapter like this
but with a couple of pins left off to go from 32 to 28.
And narrower, maybe using the pinless package, the 32M1-A, the 328-MU and the 328P-MU, both 5mm wide, while the socket pins are ~8.2mm wide
(I don't see what the difference is between 328 & 328P in the datasheet, must be something subtle I am missing).
P is the picopower variant; it uses less current and is otherwise 100% compatible.
