µVision4 User's Guide

Analog Input

µVision4 simulates the timing and logic behavior of on-chip A/D and D/A converters through:

• Dialogs from the menu Peripherals, which help to verify the peripheral settings. Analog input values can be entered directly into these dialogs.
• Virtual Simulation Registers (VTREG's) that represent the CPU pin. VTREGs can be used in expressions or debug functions.

Example of an A/D Converter peripheral dialog, where the fields Analog Inputs can be changed manually.

Script examples using VTREGs and signal functions are provided below. The signal output can be viewed with the Logic Analyzer.

• Square Wave Signal
• Saw Tooth Signal
• Sine Wave Signal
• Noise Signal
• Signal Combination

Note

• The peripheral dialog look and feel depends on the device you have selected.
