Re: Raspberry Pi 4 and Ultibo

It is some what of a mess at the moment. Laz/fpc/Ultibo run on Rasbian Buster 32, that works now. The "best" 64bit OS at the moment is Gentoo64 but that requires aarch64 version of the fpc compiler. You can get the 3.3.1 fpc aarch64 binary version, it works :D I have yet to figure out how ...

Cross.Codebot

I was googling the Cairo tools and found this, nice clock :D https://www.getlazarus.org/forums/viewtopic.php?f=18&t=40 Was looking at the code and expecting to see Cairo's C code. Hangon, that' s Pascal :o https://github.com/sysrpl/Cross.Codebot/blob/master/examples/clock/main.pas Can we use it?

Re: Getting NTP time

I found NTP happens after an IP address is assigned. 30 secs is not uncommon. Depends on you local NTP servers. I put a loop after boot to see if there is an IP Address and then another one to see if the year changes from the/a default. Ultibo has a 2sec boot and then it has to wait for the network ...

Re: Requesting tips for starting GL project

could OpenVG be used 'on top' of a GL-ES 3D-scene in the background? Probably, it has to do with the layer you use. I have had an OpenVG dial cluster overlayed on video. There is also the option of windowing. OpenVG UI surround and a "window" for the GLES/Video etc. If a video can be over...

Re: Requesting tips for starting GL project

As you are doing this on VC4 Pi's use OpenVG for dials. Layering is just done by the order they are rendered. AJ Starks is the guy who shows how OpenVG can be done. I started with the Ultibo OpenVG example and made a clock. https://github.com/Gavinmc42/Industrial-clock OpenGLES could use a library w...

Re: Additions to cryptographic support

One of the Pi forum guys posted about getting Wireguard working. My ignorance was cured with a google https://www.wireguard.com/ Would this be more suitable for Ultibo IoT stuff than ssh/ssl? 4000lines of code sounds simpler to me, but probably 100MB of dependencies? I know just enough to setup a Wi...

Re: OpenGL

The Lazarus is really "write once, compile everywhere" stuff Yep, the more I use it the more impressed I get and Ultibo is sitting in that Laz/fpc tool chain. I serious doubt any other "baremetal" toolset will be able to get close to Ultibo in usability. I have noticed the OpenG...

Re: OpenGL

Yep Pi4 frame buffer first. If the rest takes a year or two to figure out I'm not worried. The Ultibo and Lazarus/FPC world is mostly unknown to me, much still to explore. Mesa is talking to the VC6 hardware direct, no blob in the way. In theory it should be easier to port, for someone who knows how...

Re: OpenGL

A cut down GLUT replacement in Free Pascal. https://github.com/daar/GLPT Not sure why the gears demo is so slow. So many OpenGL demos and tuts in Delphi and German. But a good place to start is here, at least for some terrain and sky box stuff. http://www.sulaco.co.za/opengl.htm One of the things I ...

Re: Raspberry Pi 4 and Ultibo

Nope still pango issues.
Ultibo/Laz/Fpc where the first things I installed on my Pi4B1 but that was with the first release of Buster.
Not sure what the issue is.
