Re: Raspberry Pi 4 Thread - general discussion

Do you know what? I find talking about what you want in the the next product the day after we release a brand new product we have been working on for years quite disrespectful to the engineers involved. It's like say "Yeah, whatever, you should have done this". Can people not just be happy that we'...

Re: Raspberry Pi 4 Thread - general discussion

Do you know why they don't they work on the Pi4 ? I've just found that my own openGLES2 code doesn't work any more but I've not yet looked what has broken it. When running with the legacy GL driver you needed proprietary setup to create a surface for GL to render to (the dispmanx calls). With the a...

Re: Raspberry Pi 4 Thread - general discussion

The demos in /opt/vc/src/hello_pi/ all (well the ones I've tried) print "This demo application is not available on the Pi4" Will they be updated ? PeterO Maybe.

Re: Raspberry Pi 4 Thread - general discussion

Has anyone measured the current draw from +5V of the new Pi4 is when it has just booted up and is just sitting there, before any user input? I understand it can draw more power under load, but I am just wondering how the baseline power compares with Pi3 and Pi2. With the smaller process node, could...

Re: Raspbian 'Buster' 2019-06-20 BUG

I've assumed, perhaps wrongly, that the capability had been "disabled" by default, but could be re-instated (by the user) if required. Trev. More "hidden" than disabled. obconf is needed to set the number of desktops, and the desktop pager just needs to be added from the panel applets list. But at ...

I expect I said so at the time, but this is very short sighted !

In the mean time, the desktop pager's "Desktop Pager Settings" menu doesn't seem to do anything either though I expect the two items are related ? (Does the menu start obconf ?)

Yes, we froze the image for release last week, but have continued to push patches and fixes to apt in the meantime.

Have you upset the BBC ? They ignore the PI4 and go for https://www.bbc.co.uk/news/technology-48743043 :shock:

Maybe you should have called it "iPi4" then they would be interested :lol:

Re: Weird artifacts on dot matrix display

My experience (in 'C') with 4 x 32x32 modules in series is that you need to put some short delays in to give the data line time to settle before toggling the clock line. // Short delays for bit banging signals. void settleTime(time) { int i; for (i = time; i != 0; --i) { asm(""); // force GCC not to...
