Oh, I naively assumed that self-powered USB hubs wouldn't draw any power from their upstream port

1) What would be the "best" language to write this in? I want to be able to add the program fairly easily to any OS image I want to use. Probably BASH, as that's the language used by the rest of the Linux startup-scripts. Or you could code it in C which would be much harder, but allow it to execute...

Or simply use a powered USB hub?

I don't even think its the cpu that is the bottleneck, its the graphics on screen really and the feedback a user gets when clicking on something. For kids to keep their attention they need an instant response really. Currently the graphics are all being rendered (drawn) by the CPU (rather than bein...

I don't have much interest in emulators myself, but IIRC it's quite a popular topic in the GP32X and OpenPandora communities, if anyone's looking for some "which emulators are any good" leads...

AndrewS

Have you been in touch with the MagPi folks? Seems like there's a fair bit of "shared work" that could be done...

AndrewS

Hi Hexxeh, did you get the email I sent you a couple of days ago?

AndrewS

Seems to be something funny happening with the formatting in this thread http://www.raspberrypi.org/phpBB3/viewt ... f=2&t=4076
Notice how towards the bottom of the first page, the "poster info" box suddenly jumps left-wards

AndrewS

Any chance that some of the http://elinux.org/BCM2835_datasheet_errata might get incorporated, and a new revision of the data sheet published?

AndrewS

Awesome, loved the pic of the old CPU. 2.7kW!
Moore's Law in progress

AndrewS

Interesting, thanks for that :) Your description of "Pi 1" matches the pictures here: http://www.frambozenbier.org/index.php/tutorials/authors/liam-fraser/18983-liam-got-his-raspi Just above the SD card: Pi 1 has 1208 printed Pi 2 has 1213 printed I think these are probably manufacturing year and we...

Seems like with the new forum, unless you use multiple browser tabs, you can't see the thread you're replying to when composing your reply :( Scroll down the Reply page - the thread is below the "Options"/"Upload attachment" tabbed area. Oh yeah - a tiny scrolling view that I hadn't noticed :oops: ...

Because overclocking voids your warranty, and as JamesH keeps pointing out, the chip "remembers" if it's been overclocked.

And for anybody still interested... I've now added JamesH's finger as another layer in my GIMP project

AndrewS

Compared to the prosilver theme, the "Options" and "Upload attachment" buttons don't seem to be styled properly in the raspite theme. I kept clicking on "Options" for ages, wondering why nothing was happening

AndrewS

Apologies for bumping an old thread, but I've just re-exported all the wallpaper images now that I've fixed the aspect-ratio of the PCB in my GIMP file (which means for the 4:3 images, there's now no border). Same URLs as before...

AndrewS

<t>My git skills aren't up to the level of "pull requests" and as I don't have a RPi for testing, I was only offering suggestions rather than a completely new version of the script Re: the git pull asking for a merge commit message - wouldn't that only happen if the files in /root/.rpi-f...

AndrewS

<r>Nice I don't have a RPi yet, but as a bit of a BASH-scripter I had a quick play with it on my regular Linux box (after hacking out the auto-update and must-be-root parts). Here's my feedback: The auto-update part is quite neat The _interpreter part seems a bit pointless though, given t...

AndrewS

<t>Just uploaded some small updates: Minor graphical tidyups Highlighted the IC2 and IC3 outlines Added "All components" and "Gerbers" views Added the schematic page number for easier cross-referencing Corrected the aspect ratio and re-exported all 52 images (!)<...

AndrewS

As long as it's a regulated 5V supply, I believe an easier way to supply more current to the USB ports would be to just connect directly to the +5V GPIO header?

<t>Thanks everyone for your nice comments It's nice to see my hard work appreciated. In response to particular points: place a copy on the wiki - unfortunately the advanced html and javascript I've used can't be retrofitted into the limited Wiki markup. But as you can s...

AndrewS

Right, today's update now done, and I think it's "finished" :-) Added brief descriptions of each module Added introductory text Added cell-highlighting (especially useful in "click mode") Added a "all components" view Also painstakingly added all the pins from IC2 (BCM2835) and IC3 (LAN9512) Added a...

Everything you want to know can be found at http://elinux.org/RPi_Hardware

However there's no GPU-side drivers for the DSI or CSI interfaces yet, so these slots are currently unusable.
