Abstract:

The principle of the best geometrical way beeline interpolation was given, and the method to lattice graphics LCD display was introduced. The requirement for data conversion and program diagram was given, which can be realized with C51 advanced language. This method can be applied as a base function module in the MCU system of a real time display curve graph. In addition, this way has proved its practicability for the low deviation——half step and high real time performance.

Key words: best geometrical way; beeline interpolation; MCU; lattice graphics LCD
