PICAXE VSM also supports thousands of traditional components such as 555 timers, op-amps, CMOS & TTL logic etc. 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. Virtual instruments such as ammeters, voltmeters and oscilloscopes can be connected to any pin or wire to study the circuit operation. 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. LEDs, motors and LCD 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. Then associate your our PICAXE BASIC program to the PICAXE chip component and click ‘Run’ to watch the circuit in operation. Add voltage/current probes to any point in the circuit, and then connect any virtual instruments (e.g. To use PICAXE VSM simply draw your circuit schematic on screen, using the automated wiring and library of over 12,000 popular analogue / digital components to build up your circuit. 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!
