Re: Raspberry Pi bare metal - Ultibo and Nim

We have been working on creating an API that exposes the full Ultibo feature set to other languages, Wow, not thinking small then ;) I guess that would be why it has been quiet on new the releases? Inverts all my thinking to date. This Ultibo is too flexible, I'm still struggling with the VC4 stuff...

Tensorflow

Today's Raspberry Blog has a bit on AI using Tensorflow.

This compiles the Tensorflowlite version into a library.

Would it work with Ultibo?
How do you find out if it has Linux dependencies?

Re: Raspberry Pi bare metal - Ultibo and Nim

Hi Mark,
You might have to dumb it down for me, I am just a hardware guy trying to learn coding.
Nim seems to be a language,

How is it being used with Ultibo and why are you using it,
Which led is blinking?
I see what looks like the Ultibo Web Status page and what?

Re: Hello_Video + overlay

Camera example is fun to play with, moving the display window around etc :D Probably should have looked at that first ;) Paul, how long did it take you to get these to work? And how did you debug them? Once again Ultibo just works because better people than me are coding it :D Made the videotest exa...

Re: Hello_Video + overlay

Thanks guys. Note that OMX is very fickle. Setting some parameters may cause the program to hang or error out. Yep found that out ;) I am pretty sure start_x has the Camera ISP code in it as a hexedit shows lens colour/correction comments. Normal start.elf is ok for OpenVG, OpenMAX etc I have yet to...

Re: Hello_Video + overlay

Paul, your OMX video player ran all day in a loop, more than good enough for this current app :D But boy is Dispmanx/EGL/OMX documentation a mess, how did you ever get the ported code to work? If I can figure out the layers and overlays a camera version will be interesting. FPV transmitters with Zer...

Re: Hello_Video + overlay

OK getting confused.
Now have Console, OpenVG and OMX video all going, transparency on OpenVG sorted.

But how do I control which layers each goes on?
How to size/place the OMX video less than full size?

Re: Hello_Video + overlay

Reading up on OMX leads to the OMXplayer
https://github.com/huceke/omxplayer

There should be clues in there for overlaying :D

Re: Hello_Video + overlay

Another one of my senior moments :oops:
It works if I name the second file correctly ;)

Now there are two ways to play videos with Ultibo that boot in 5 seconds.

Re: Hello_Video + overlay

Wow, I put a bigger file in and it just worked. Now I need to learn this OMX stuff too. Not sure what all your network stuff is for? Just commenting out the {$define use_tftp} makes for faster boot, still about 5secs. This means the Hello_Pi C libs are not needed? Pure Pascal :D I am trying to play ...
