The current situation with secretive GPU information is not good but the public seem happy to accept it. Or maybe the public just don't care as long as the latest game will run without crashing?

Are these well documented arm devices compatible,or everyone needs to rewrite code for it?

Very cool, good job. Are you using the built-in gpu?

Wow Dex, what a great idea. Good looking port so far, though, Have you overcome the data type issues I was having when I wrote MacroBASIC?

I'm waiting for the source code if possible with explanation. The most interesting for me is the whole initialization issue.

If the latter is true you would only need to put in a 5v run to the keyboard and some transistors in an "open collector" configuration to act as buffers between the voltage levels.. You should, actually, be able to get the 5v off of the USB ports, and use a small adapter board to avoid any cutting around on the main board. Even simpler than open collector transistors could certainly be simple voltage dividers off of the keyboard output and some quiet prayers that the input will trigger at 3.3.

Or use an IC voltage translator instead.

Lol @ your reply. I was taking no credit for your codebase, however I did propose the idea as early as 2005 to make a language to go between platforms, which you brushed off at the time, (and again in 2009). And the sidetrack you took is certainly off topic, so to return:

Is the entire Raspberry Pi 3.3V, or is there a 5V supply to the device which is stepped down on the board?. If the latter is true you would only need to put in a 5v run to the keyboard and some transistors in an "open collector" configuration to act as buffers between the voltage levels.. You should, actually, be able to get the 5v off of the USB ports, and use a small adapter board to avoid any cutting around on the main board. Even simpler than open collector transistors could certainly be simple voltage dividers off of the keyboard output and some quiet prayers that the input will trigger at 3.3. You'd still need the 5V supply off of the USB

Just real quick, so as to exonerate my completely benign earlier comment (which was taken entirely too far):

This was uploaded, and a link sent out to anyone active in the project at the time. You'll note it's public domain, so obviously I'm not all that concerned, my humor was in the fact that you brushed it off repeatedly as insignificant, and are now building upon the idea.

Live and let live, I'm here to learn and to continue doing what I love doing.

They're changing their bootloader constantly then? That sounds like a headache and a half. I've not been able to order one, maybe I'll hold off.

I'd go with the FET solution, but that's mostly due to my engineering background. A lot of automotive sensors (my actual job) use an "open collector" output, of course the name isn't totally accurate as the transistor in question is a FET, making it "open drain". Very effective, cheap, and reliable for getting a 5V output from a 12-14 Volt sensor.
