Re: Rapberry pi 4 IO memory base address

However, those particular fields have disappeared ... so someone using the above code would also need something like my stuff below if it is required to run on older Raspbian systems extract from the diff ... + if ((fp = fopen("/p...

Re: Rapberry pi 4 IO memory base address

Update from LCDProc ... they now consider having specific RPi module for GPIO-based devices as obsolete and instead they want to control via libgpiod. So ... quick question ... does libgpiod know about the RPi4 base address or whatever it needs to access them? Edit: Someone with access to RPi4 (mine...

Re: Rapberry pi 4 IO memory base address

I have created an issue on LCDProc github with link to this. I submitted a change to LCDProc for older RPi when base changed for the first time - but this time around it is probably best to fix it in a more generic way. What timescale for the updated official way and how backwards compatible will it...

Re: Rapberry pi 4 IO memory base address

Is there an official way to get the base address at runtime (i.e. not using defines). With older Raspbian builds it could be found via /proc/iomem with different keywords depending whether or not device tree was being used. https://www.raspberrypi.org/forums/viewtopic.php?t=100066 Edit: changed /dev...

Re: Pixel Doubling

I remember seeing something about it on one of the many launch days videos that I skipped through.
It said no pixel doubling in RPi4 but there use different modes to achieve same effect .... but I don't know which (all my RPi run headless).

Re: Raspberry Pi 4 Thread - general discussion

A shim to convert from USB-C power supply to micro-usb (the other way around to the one on launch day) would mean RPT could drop the other power supply.
Is there a plan to do that, perhaps when stocks old the old supply run down?

another way to achieve similar result is to treat the Pi as something like a Smart TV and the TV as a dumb screen. You could do this by installing Kodi on the Pi (along with some plugins such as “iplayer" to access BBC content. Possible to get YouTube working but perhaps not so easy for Netflix or A...

Re: Do I need a WVC1 License?

No.
Plus, if your needs do change in the future then you can add it later.

The MPEG2 licence is useful if dealing with TV recordings (in some countries) but the fastest RPi devices now seem to do an OK job handling that sort of material using software decoder (without the extra licence)
