Analog Devices ADuC7000 PWM Example

This ARM example runs on the Analog Devices ADuC7024 and shows:

  • Usage of the PWM pulse-width modulator,
  • A Timer Interrupt Service Routine in C,
  • How to generate a Sine Wave Output Signal (on DAC0),
  • Analog-to-Digital Converter (ADC) Input (on ADC0),
  • and Digital-to-Analog Converter (DAC) Output.

This project is created using the Keil ARM CA Compiler.

The Logic Analyzer built into the simulator may be used to monitor and display any variable or peripheral I/O register. It is already configured to show the PWM output signal on PORT3.0 and PORT3.1

This ARM Example may be debugged using only the uVision Simulator and your PC--no additional hardware or evaluation boards are required. The Simulator provides cycle-accurate simulation of all on-chip peripherals of the ADuC7000 device series.

You may create various input signals like digital pulses, sine waves, sawtooth waves, and square waves using signal functions which you write in C. Signal functions run in the background in the simulator within timing constraints you configure. In this example, several signal functions are defined in the included Startup_SIM.INI file.

For users with functional hardware, you may use the Keil ULINK USB-JTAG Adapter to download your application into Flash ROM. ULINK allows also debugging of the application on Target Hardware using the ARM7 Embedded ICE. Refer to for more information.
