Re: Call for review: fixing OpenVG wrapper library reliabili

I found out that I forgot to update a structure.
A new version of the FreePascal bindings will be available either today or tomorrow.
There are some intermittant hangs, like with the C code, but overall quite stable.

Re: Call for review: fixing OpenVG wrapper library reliabili

I just noticed - when updating my old code to reflect Pi2-3 - that the current binary is far less stable than the initial one. I can query information but the real demo (my pascal sourcecode) doesn't work anymore. It works with the old code and the provided pascal binary in my original package for t...

Well yes and no: Graphics acceleration in general is for the monitor you are looking at, in your case a client computer which has its own graphics card. So that one should be accelerated ;) Through its own OS features and its own graphics driver. See the point? But graphics rendering can be a bit qu...

Nou, KPN hotspot is technisch gesproken gescheiden van jouw thuisnetwerk. Wat wel kan, is met je Pi inloggen op het kpn netwerk als je een wifi dongle hebt. Wat ook kan is thuis zorgen dat je op de KPN router (niet alle!) DMZ instellen voor het lokale ip adres voor je pi. Dan kun je een webserver of...

No, not yet.
But it is no problem for me to also build Lazarus, automated.
Just don't expect support ;-) I (frankly, almost) don't use Lazarus ;-).

If you want, I can also do weekly Lazarus builds from trunk.

Re: Free Pascal Install after Lazarus

I still recommend 2.7.1 for the Raspberry Pi: it is orders of magnitudes faster than 2.6.X for armhf. In some cases twice as fast.
I gave instructions previously here on the forum and am still building at least weekly.

Re: Freepascal error with SDL

First, you have to check where libggc.a is installed. You can find it by typing; sudo / -name libgcc.a It is probably in /usr/lib. In that case type: export GCCLIBDIR=/usr/lib Now fpc will be able to find GCC. Let me know what the next error is. Otherwise install FPC2.7.1 from http://freepascal.thad...

Freepascal 2.7.1 Daily builds

I have decided to push daily builds for the latest and greatest version of the Freepascal compiler to http://freepascal.thaddy.co.uk/raspberrypi.html The reason for that is that the official Freepascal distribution for Raspbian is many, many versions behind and trunk contains many, many language imp...

Checkout the watchdog timer. That can do a reboot from power down as long as the power-supply is not interrupted, I believe.

Re: Need to disable USB, but not network

I would go for simply custom housing and have a custom pi box made. If you are really shipping numbers costs would be OK.
If you have a box that doesn't expose USB ports, users can't use it. And a sealed container is less destructive than some of the options suggested.

Re: USB sound issues

The problem is not likely the audio, but disk io and possibly networking. Disk io can be mitigated in software by buffering/caching. networking can be mitigated by multiple configuration options. e.g. a smaller packet size, say 512 in stead of 1536 may prevent dropouts on the audio side. You can als...

Re: USB sound issues

It is more an issue that the usb bus is shared. How many devices do you have connected?
Try to limit them, especially disks etc, that require high throughput. Audio (stereo 16/44100) is not that bus bandwidth intensive, but disks are... As are high speed wireless network cards.

Re: OpenVZ

OpenVZ is in many respects just chroot. Why not chroot these services yourself? Or even a chrooted OS like Arch running the services? That's perfectly feasible on the pi.

Thank you for your elaborate answer.
So basically when I am tinkering with compiler building /code generation itself, build it for VFPV2 code generation. I will leave my stuff as is, i.e. VFPV2.

Re: How to get global IP for Raspberry Pi

Your router has probably an option called "port forwarding". Enter your router's setup and configure port 80 to be forwarded to your local ip address and all should be fine. This means that no other person in the house can run a website from port 80, though. And your provider may have cut it off. Yo...

It means the driver was expecting to have something to do, but there wasn't any work.

Re: Working with Interrupts on RaspberryPi

In the context of just IO and interrupts it may very well be convenient to write a class with only static functions is my premise.
That would make for somewhat more centralized, readable and maintainable code as opposed to a pure C api.

Re: Working with Interrupts on RaspberryPi

That's what I always wonder ;-) But think about it: in the context of the subject a static function would suffice in most cases. But if you mean that the average C++ programmer likes to - unintentionally (imnsho) - over-engineer their code, you are bloody well right ;-) I am sometimes one of them.
