Product Details
PICAXE Virtual System Modelling (VSM) is a software circuit simulator, that combines a ‘virtual’ PICAXE chip with animated components and Berkeley SPICE circuit analysis to produce a simulation of a complete PICAXE project – and most circuits simulate in real time!
To use PICAXE VSM simply draw your circuit schematic on screen, using the automated wiring and library of over 10,000 popular analogue / digital components to build up your circuit. Add voltage/current probes to any point in the circuit, and then connect any virtual instruments (e.g. an oscilloscope) as required. Then associate your our PICAXE BASIC program to the PICAXE chip component and click ‘Run!’ to watch the circuit in operation.
The on-screen output components (e.g. LEDs, motors and displays) animate as the PICAXE program runs, and input device such as temperature sensors, switches and keypads can be activated by clicking on the animated model in the circuit simulation.
PICAXE VSM also provides extensive debugging facilities – the PICAXE program can be stepped through line by line, breakpoints can be set in the program, and the variable values can be displayed on screen.
Virtual instruments such as ammeters, voltmeters and oscilloscopes can be connected to any pin or wire to study the circuit operation. Voltage and current can also be highlighted by various animation options, for instance by adding ‘voltage bar graphs’ to component pins or by automatically changing the colour of wires.
PICAXE VSM also supports traditional components such as 555 timers, op-amps, CMOS & TTL logic etc. A series of electronic principles tutorials are even included free of charge! Traditional components can be simulated in circuits by themselves, or combined into a PICAXE circuit. You can also add multiple PICAXE chips to a single circuit so, for instance, two chips can communicate via RS232 serial communication.

Click here to download a demo version of PICAXE VSM. The software will run in 'demo' mode (see the example circuits in the demo folder) until a licence key is purchased (i.e. the same installation is used for both demo and full versions, with a licence key 'unlocking' all the features). The licence key is non-expiring (can be used forever) and also includes one year of free updates. After one year any updates can be purchased for a small renewal fee.
