12 REV. PrC 02/05
The ADM8843 software GUI allows the user to program the on-board ADuC832 to generate a PWM signal from 100Hz to 200 kHz
with a duty cycle from 1% to 100%.
1. The user can enter the required frequency in Hz into the frequency text box and press the update button.
2. Also the user can enter the duty cycle required and press the update button.
3. Then the corresponding values can be written to the ADuC832 over the parallel port to the eval board by pressing the Write to
ADuC832 button.
4. The values of frequency and duty cycle which are written to the ADuC832 are shown on the software GUI.
and
5. The user may also use the vertical sliding bars to select the frequency and duty cycle required.
