Re: HVS, Hardware Vector Scaler

Thanks pik33, simple must mean something else to you :D
I will try to figure all that out ;)
Just knowing it has been done helps.

HVS, Hardware Vector Scaler

The VC4 has lots of stuff in it, one is the Hardware Vector Scaler I noticed the HVS registers when looking at Eric Anholt's VC4 driver source. Has anyone used the HVS yet in Ultibo? Simple example please pik33. I was able to shrink my Steampunk OpenVG objects down to icon size with just a scale mul...

Re: OpenVG- baremetal VG

Should be easy enough to make a Go version of my SteamPunk OS screen? It was very easy to port to Go on Raspbian, not so easy to just copy that port to PiCore, dependency hell as per normal for Linux ;) Need to try Gentoo64 next, that's should break it? The more I use Ultibo the easy it is compared...

Re: Displaylink

I think you are confusing Console with Framebuffer, the DisplayLink if implemented would appear as a framebuffer device in Ultibo and the framebuffer console driver (CONSOLE_TYPE_FRAMEBUFFER) would automatically work with it the same way it does with the TFT framebuffer devices. Both console and gr...

Re: Displaylink

VNC and Displaylink, remote desktops etc all have clients/servers. Nothing wrong with using Ultibo and Pi's at both ends. Since I know near zero about comms protocols i will go back to my eReader Steampunk OS. But looking at a way to script the OpenVG UI from a text file. Make it independent of any ...

Re: Displaylink

My whole point of Pi's is to learn stuff, even if it is how to make wheels ;) And to explore new ways of doing things. Ultibo just makes it easier to learn to do stuff. Doing an OpenVG accelerated remote display protocol does look like it is within my limited capabilities. Pi as server, Pi's as clie...

Re: vnc - virtual network computer - ultibo

VirtualGL and WebGL are remote graphics protocols.
WebGL is interesting because it uses OpenGLES2, WebGL 2.0 is less interesting ;)

VNC that uses WebGL?
Sometime I really hate Pi's and Ultibo ;)
Together they give me too many ideas and I lack the skill and time to do most of the ideas. :(

Re: vnc - virtual network computer - ultibo

Running AJ Starks Go OpenVG code on Raspbian via VNC is a useful way to code the look and feel without burning SD cards. Wasted most of last weekend with a dodgy SD card. Took longer to get a Raspbian SD running with everything installed than actually hacking the Go examples to put a brass round rec...

Re: Displaylink

Been thinking about a VGconsole unit, so had a look at the two console files. Did not even pay much attention to these ones before . CONSOLE_TYPE_SERIAL = 2; CONSOLE_TYPE_REMOTE = 3; CONSOLE_TYPE_LCD = 4; Displaylink would be the graphical version of CONSOLE_TYPE_USB = 5;? In the graphicsconsole the...

Re: Displaylink

since we don't have any DisplayLink devices it's unlikely to be us. Me neither but I have a bunch of Zero's ;) Not sure how that differs from RDP, VNC, VirtualBox, VMware etc that we all use everyday. No idea either? Probably plenty of ways to do it already, reinventing the wheel? After looking at ...
