KTechlab is an open source IDE for electronic and PIC microcontroller circuit design and simulation.
It is a circuit designer with autorouting and simulation of common electronic components and logic elements.
KTechlab supports programming microcontrollers using a graphical flowchart based language called flowcode.
The software uses Qt.
Key Features
- Circuit simulator, capable of simulating logic, linear devices and some nonlinear devices.
- Integration with gpsim, allowing PICs to be simulated in circuit.
- Schematic editor, which provides a rich real-time feedback of the simulation.
- Central working canvas between sidebars as shown in the picture on the left.
- Flowchart editor, allowing PIC programs to be constructed visually.
- Circuit diagrams (or captures), flowcharts and code (c or assembly) are displayed as tabs above the design canvas in the main window.
- Flowcharts are useful for defining the control flow of an algorithm to be run in a programmable integrated circuit (PIC).
- Analog or digital circuits can be drawn and simulated “on the fly” while they are been built and measurements such as the branch current or a node voltage can be displayed by hovering over the circuit with the mouse.
- Electrical Components Sidebar.
- Item Sidebar.
- MicroBASIC; a BASIC-like compiler for PICs, written as a companion program to KTechlab.
- Integrated assembler and disassembler via gpasm and gpdasm.
