Re: Code between framebuffer and output?

Also note, for now I am not asking for details on /how/ to do it, just if VideoCoreIV can support doing such a thing.

Code between framebuffer and output?

(Hoping this is a suitable forum - the query seems more bare-metal-ish than graphics-ish - it is certainly a very very low-level query, well below any potential OS-layer! TBH, if no-one can answer it, I won't be overly surprised, it is very obscure :-) ) I am wondering if the VideoCoreIV subsystem h...

Re: What was your first computer?

<t>(1984) I started with a Dick Smith VZ-200 (Z80CPU and an attrocious TeleType video chip – no lower-case characters!) which I bought off a schoolmate for $50 (they retailed for $200). I sold my entire Lego collection (which was extensive) to raise the money. They had Apple][ machines at school, th...

Re: DisplayPort?

FYI: I plugged in some DisplayPort cables the other day and was surprised when the audio came through the monitor's speakers, so it does support audio. As enthusisatic as I am about DP, I am still with HDMI for now only because of its relative ubiquity.

Re: Wishes for 2nd gen Raspberry Pi

Something like this:

Variations with other usb devices in place of some upstream ports also possible, of course (for example, a USB-ethernet plug in place of the left-most USB socket, possibly rotated to be facing the same way as the one on the RPi).
