Hello everyone,
I have been using this electronic application called ktechlab for a while,i found that it is a pretty good application for electronic ppl,ppl who design circuits,ppl who write microcode and for ppl who want to build PIC.
KTechlab is a young open source electronic design automation software. It supports real-time electronics simulation and PIC microcontroller debuggin.
KTechLab includes a whole programming language called MicroBASIC and associated compiler for programming PICs. It can compile the flow diagrams into MicroBASIC and from there into an assembly language compatible with MPASM as used by the manufacturer of PICs. The assembly language can be compiled into a machine code suitable and compiler for feeding into PICs.
KTechLab uses the KMDI interface familiar to users of Kate or KDevelop. (You can change this layout but this seems to cause problems and KMDI is the most usable.) Diagrams and code are displayed as tabs and each diagram is saved as an XML file using a custom language and a file extention of .flowcode or .circuit. You can group together diagrams and code files into projects which makes a file with a .ktechlab extention that points to the other files but I wonder if it would be more intuitive to just have one file for all your diagrams and code.
Around the edge of the canvas you’ll find electrical components which can be dragged onto circuit diagrams and flow parts for flow chart diagrams. I usually find it best to keep this left hand sidebar open all the time when working, you can do this by clicking on the “Overlap” button (square icon) at the top of the sidebar. On the right hand side is an Item sidebar which gives information and lets you set properties of the currently selected item in the diagram. There is also a context help sidebar giving a helpful description of the currently selected item in the diagram. Many Free Software applications are criticised for their lack of documentation so it is refreshing to find one which goes out of its way to provide extra documentation.
Having worked on Umbrello which also draws diagrams I find myself jealous at the intelligent way the connections joining diagram items route themselves. You can also do manual connection routing if you are not happy with the automatic routing. Diagrams can not currently be resized or zoomed, maybe this will be added in future versions (although it is actually quite difficult to get QCanvas drawings to be resizable on the top and left hand sides).
Using KTechLab
A flowchart is probably the best place to start. In the top left or the diagram is a picture of the PIC chip, this show its initial settings, it is not part of the flowchart itself. You can change these initial settings by clicking on each connects of the PIC to turn it on or off, clicking and dragging left or right will set it to be an input or an output. Flowcharts need a start and end which you can drag in from the flow part sidebar. You can then drag in any of the other flowchar actions and connect them together. Dragging in a subroutine adds a large diagram item into which you can put other items.
Once you have your flowchart you can convert it into microbasic, assembly code or directly into machine (hex) code by using the buttons on the right hand side of the toolbar (or from the Tools menu).
Now we can make a new circuit diagram. The Components sidebar contains assorted electrical items that can be dragged onto the diagram. At the very bottom is a PIC 18 Pin item. If you add this to a diagram it can be associated with the flowchart you just made (or one of its code representations). Click on the PIC and point it towards the file with your flowchart by editing the filename box in the toolbar. If you now run the PIC by clicking the play button below it the circuit should run according to your flow diagram, you can see the output in the gpsim box at the bottom of the diagram.
But alas Looks like the Developer is no longer working on the said application and no new releases have been issued so i believe that this application wont be going any further ,so it needs developers,geeks to help it start again.Pls guys dont let this appln go down the drain ,It needs Your help.
The sourceforge repository retuns nothing so if you want the packages you will have to download it from rpm.pbone.net.”A word of caution for opensuse users you will have to satisfy many dependencys before you can have it working” ,but it works i have it working on my opensuse 10.2 machine.
PLS HELP KTECHLAB.
