MUIPlot – a simple function plotter

Posted by ALB42 on 13. November 2018No Comments

I used the function parser for a function plotter before when testing the TAChart for LCL. Now I gave my Plot component I use for MUIMapparium a little bit of reshape and fit it into MUIClass components and created a new function plotter.

I little video to show how it works:

Running on a Amiga 1200 with 68030 50 Mhz and 68882 50 Mhz on a 32 color AGA Screen. For Hex2 the floating point calculation speed is not very important, because it’s just a single function. But for calculating the full curve it needs a little bit more floating point calculations. Therefore a FPU is included. Also you should limit the number of Points to calculate to for example 100. For NG Amiga systems of course you can increase it to higher numbers.


Hex2 0.2

Of course, when publishing a new program the people will find some problems. Good so at least some used it :-P. I made a new release. Added integer divide and modulo and repaired the swap function (swap endianess) and fixed some minor bugfixes and number overflows.

Downloads for all Amiga Platforms:

Download for all Amiga Systems

The program is based on a very old program (written around 2005) written by me so of course it is also available for Linux and Windows. It has a little bit smaller feature set than the Amiga version but it was always useful for me 😉

Have fun! 😉

Full Hex2 MUI port

Posted by ALB42 on 9. November 20182 Comments

I created a little MUI interface for my commonly used calculator Hex2. I use it often for bitwise comparisons to easier see shifts on bits.

If you don’t know it, Hex2 is a programmer and scientific centered calculator with variables support and a little GUI even it’s keyboard centered. Of course I created it with MUIClass, therefore its available for all the common Amiga platforms.

ExtronControl 0.1

Posted by ALB42 on 3. November 2018No Comments

First real release of the Extron Control as Version 0.1.
Control Software for Extron DSc 301 HD, Scaler and input switch.

With the new version you can configure, which parts of the GUI is visible (via tooltypes) and also configure the names on the Input Switch Buttons and which serial device to open and search for the Extron DSC 301 HD.

For Amiga and MorphOS the executable is included. But the source is also in the archive, hence one could compile them for AROS or OS4. (it just needs the latest Version of MUIClass).

Have Fun.

ExtronControl for Extron DSC 301 HD

I bought that device, its a very nice scaler nicely usable for old computers to bring the image in a good quality to modern monitors. I supplies a serial interface for controlling (beside the on screen display) but only a Windows program to use it. I wrote a little program to operate this device from Amiga/MorphOS (where you can use the USB connector at the front panel as a USB2serial bridge). Already working very nicely, some screenshots.

You can switch the inputs, it shows which input is selected (it also notice the change when you using the front panel). When an input has a usable signal the button is printed in bold. It’s an very early version but works already nicely, if someone it interested I just make a download available here (binaries for Amiga68k and MorphOS and the full source, licensed under CC0, it needs the last MUIClass package to compile, just yesterday I fixed some bugs there, should also compile for the other Amiga platforms) have fun.


Sodoku for Workbench 1.3

Posted by ALB42 on 16. Juni 20182 Comments

I packed Sodoku as an ADF, not bootable becasue it needs intuition.library, so you have to load Workbench first. It needs around a 1.5 Mb RAM. Sadly I still not get the newer FPC Version to work (strange crashes, looks like some memory corruption, because it always crash at different positions) so the executable is still rather huge (550 kb vs 52 kb) and therefor needs a lot of memory to load it.

Playing on Workbench 1.3

Posted by ALB42 on 15. Juni 2018No Comments

I dig out my old Version of FreePascal for Workbench 1.3 and I tried to use it with the latest FreePascal, and it seems not to work. Thats bad because the smaller exe size was after that, so the executables are still quiet big.
So I should check again how to do that.
But first I played a little bit with it and wrote a little Game for the Workbench. A Sodoku which worked quiet nice, just the graphics is rather difficult because many of the convenience feature to create Bitmaps and rastports and so on are not there so you have to do it by hand.

But finally it works:

25 years of FreePascal

MAybe you do not know it but FreePascal turned today 25. On 8th June 1993 Florian Klaempfl started with current FPC source base.

I will take this opportunity to say thanks for that. It’s an awesome program and becomes better and better Also thanks to ChainQ which gave me the the chance to use my favorite language on my favorite computer system.

Happy Birthday FPC 😀

MUIMapparium AGA on a native Amiga

Posted by ALB42 on 31. Mai 2018No Comments

I tried the MUIMapparium on my real Amiga 1200 with 680030 50 Mhz (With 68882 FPU). Good news, it works somehow, of course it is slow but once the images are loaded, it moves ok. Unitl now it freezes a little bit when release the mouse button… maybe I should try to find the reason for that.
I also tried on a 16 color screen, much faster… but looks awful 😉 so I decided to make the Video with a 256 colors screen 😉 even it’s slower.
