Wow!  I'm hoping to try this soon to make a console version of Control Terminal http://ctrlterm.com/ and now I'm wondering if FreeVision http://wiki.freepascal.org/Free_Vision will work in the console?

I have a few related links here: http://ctrlterm.com/ports.htm

How much work would be needed to get FreeVision and the IDE http://wiki.freepascal.org/Textmode_IDE working?  Seems like fun times ahead!

At a quick look I don't think it would work currently, mainly because it seems to be character based and the Raspberry Pi has no character mode display (only a pixel mode framebuffer).

I think the API could be implemented fairly easily but handling the movable windows etc would require some effort, in a character interface maintaining a buffer that describes each window is fairly quick and simple. Maintaining a buffer that holds the pixels for a full HD display in 32 bit color takes a lot of data manipulation.

If you were happy to start with a single text mode window with a FreeVision API then the current console unit could be used as is and the API could wrapper over the top.

How much work would be needed to get FreeVision and the IDE http://wiki.freepascal.org/Textmode_IDE working? 

I'm assuming from what I read that if FreeVision worked then the IDE would also work.

On the other hand your url for Control Terminal mentions fpGUI which according to this post https://ultibo.org/forum/viewtopic.php?f=13&t=17 might be able to be ported without a huge effort.

Wow, That's what I want.

really cool :)

I will try to other peripherals on your rtl.

Many Thanks.

Is there any screenshot? photos?


I couldn't imagine what I can do with Ultibo+RaspberryPi %)

Or MSEgui which also is a self drawing GUI toolkit for FPC with a dedicated development IDE (MSEide). Either by implementing a backend for the frame buffer or to the GPU. Advantage of MSEgui is that it is more sophisticated, advantage of fpGUI is that it already has a framebuffer backend by AggPAS.

it seems I managed to compile freepascal arm-ultibo on mac, but I have not tried even further, my raspberry pi still on the way  8)

Awesome  :D

When you prove it works it would be great if you could post the instructions somewhere to share with others.

Nah, it's fairly easy todo ;-)

Adapt unit video to do your bidding, i would start there.

Yes.

Please have a look at amiga unit video here.

Amiga, AROS and MorphOS also don't have a 'real' console mode, it's all graphics emulating the charcter based console (and FV and IDE are working perfectly). The native platform does provide API that makes things a bit easier, i have no idea (yet) how easy it would be to implement using your exposed API.

Thank you for your project Ultibo, at first glance that really looks interesting (*wow*)

PS: for some reason my older opera browser refuses connection to the url you posted. If i get a response from the server at all (unable to access address) it is "Secure connection: fatal error (40) from server."

Don't tease!  I have 3 Pi 2's on my desk and need this in OSX.. I ran all the demos on the WM Windows but that is painful.........

Okay I will share the steps I did, although not yet proven whether this running properly
Code: Bash  [Select]
  1. make distclean OS_TARGET=ultibo CPU_TARGET=arm SUBARCH=armv7a CROSSBINDIR=~/Documents/gcc-arm-none-eabi/arm-none-eabi/bin/
  2.   CROSSOPT="-CpARMV7A -CfVFPV3 -CIARM -OoFASTMATH"
  • type and wait
Code: Bash  [Select]
  1. make all OS_TARGET=ultibo CPU_TARGET=arm SUBARCH=armv7a CROSSBINDIR=~/Documents/gcc-arm-none-eabi/arm-none-eabi/bin/ CROSSOPT="-CpARMV7A -CfVFPV3 -CIARM -OoFASTMATH"
  2.  
  • type and wait, I assume your fpc 3.0.0 is in the folder /usr/local/lib/fpc/3.0.0/ so option INSTALL_BASEDIR become INSTALL_BASEDIR=/usr/local/lib/fpc/3.0.0/
Code: Bash  [Select]
  1. sudo make crossinstall CROSSBINDIR=~/Documents/gcc-arm-none-eabi/arm-none-eabi/bin/ CROSSOPT="-CpARMV7A -CfVFPV3 -CIARM -OoFASTMATH" OS_TARGET=ultibo CPU_TARGET=arm SUBARCH=armv7a INSTALL_BASEDIR=/usr/local/lib/fpc/3.0.0/

    but, I have a question for @ultibo, is there any spesific feature on fpc trunk or 3.1.1 , instead of using the stable version 3.0.0 ?

    This might be similar to the problem that older versions of IE have, our web host does not accept TLS 1.0 so in IE10 or earlier you have to enable TLS 1.1 and 1.2. Older version of Opera could be having the same issue.

    Yes, there are two commits to FPC trunk that are required:

    http://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/compiler/arm/cgcpu.pas?revision=32788&view=markup

    http://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/rtl/arm/arm.inc?revision=32788&view=markup

    Both relate to the generation of BLX <Label> instructions by FPC which needs to be BL <Label> instead. Apparently the linker should fix these up based on the mode (ARM/Thumb) of the code being called but it does not (anymore) and so gcc and clang also now use BL instead.

    I did the original development work with 2.7.1 trunk so as far as I know all of our changes to the compiler and RTL could be applied to 3.0.0 if the above patches were also applied.

    All successful!  I replace the two mentioned files with the patched ones before I ran this with my 3.0.0.  I am sorry but I am not a command line jockey.  What is suppose to happen once done?  I do have the compiler binary but a couple of things happened.  The build created a folder 3.1.1 folder next to the 3.0.0 with part of the files in there.  If I type "fpc" the darwin compiler is still the linked compiler or if I try to build lazarus it fails.  If you follow the directions on the Ultibo site with the path link to the right compiler the lazarus make gets a bit further but needs libraries it can't find in the make.
