用PIC單片機與AVR單片機製作PLC控制的階梯圖程序。

//-----------------------------------------------------------------------------
// Description of the intermediate code that we generate. The routines in
// intcode.cpp generate this intermediate code from the program source. Then
// either we simulate the intermediate code with the routines in simulate.cpp
// or we convert it to PIC or AVR instructions so that it can run on a
// real device.
