Re: Demoscene

Can Ultibo be used to code Demoscenes? https://www.raspberrypi.org/forums/viewtopic.php?f=72&t=227424&p=1395154#p1395154 Smallest kernel.bin I can make is about 260KB, it does nothing. So how to turn just about everything off and make a minimum kernel.img that just does graphics? By design ...

Re: Shift State

I am trying to translate some Delphi VCL code over to Ultibo and are currrently working on the OnMouseDown events. I have most of it working but am coming a bit stuck on trying to read the keyboard modifiers (e.g. Alt, Ctrl, Shift). The modifier information comes from the Modifiers field of the TKe...

Re: Using the ActivityLED to show IP address

I don't know if this can be of some inspiration for what you are pursuing: https://sourceforge.net/p/xmlrad/code/ci/master/tree/XMLCLX/UPnP.pas The logic of this unit is used to map an appliance behind a NAT (an ADSL box) and expose it to be addressable from the wild Internet. Thanks Jyv, that cert...

Re: UTF8

Where are the UTF8 functions located? Hi Paul, It depends exactly which functions you are looking for, the System unit (included implicitly by every other unit) contains a number of low level UTF8 conversion functions like: UnicodeToUtf8 Utf8ToUnicode AnsiToUtf8 Utf8ToAnsi Utf8CodePointLen UTF8Enco...

Re: Question about dtoverlay, e.g. for 3rd party LCD

Hyperpixel is a cool display, but may not be the best example for this discussion, since it uses basically all the Pi's GPIO. Still, I had hoped to get it working with Ultibo, but haven't had any luck yet. Changes to config.txt are necessary but not sufficient, it seems, as getting it working with ...

New Raspberry Pi 3 Model A+

In case you haven't noticed, a new model of the Raspberry Pi has just been released. While it isn't the much anticipated Pi 4 that many are waiting for, the new Raspberry Pi 3 Model A+ is something that will be popular with quite a few as the big brother to the now fairly old original Pi A+. You can...

Re: Still confused about graphics options

One specific thing I want to try is mirroring part of the HDMI screen on an LCD like PiTFT35. I am working on an example based on the Asphyre demo, and thinking there should be an underlying bitmap for the active HDMI display that I could do a CopyRect from. Any hints on how to access that? As pik3...

Re: Using the ActivityLED to show IP address

Garry, do you have any thoughts on https://en.m.wikipedia.org/wiki/Universal_Plug_and_Play which could serve a similar purpose? Hi Mark, It's very likely that UPnP could be a good fit for the kinds of things people would want to use Ultibo for. The one thing we're missing right now is multicast sup...

A retro future, without the past

You might have noticed that Ultibo has been used in quite a few retro projects over the past couple of years, that's probably not surprising really since there is a huge interest worldwide in all things retro including computers and gaming. It also could be a reflection of the Ultibo model which rem...

Re: Vector Graphics

Has anyone experimented with FPVectorial. I am looking at redoing my graphics canvas and would llike to add SVG support. It does not seem to be loaded into the core by default. We haven't tested or explored FPVectorial in any way (someone else might have more direct knowledge) but a couple of obser...
