9.2 Blinking/dimming with the PCA9530 demonstration steps
10. Slide the selection tab on LED0 to the ON position.
11. Verify the RBG LED is ON, displaying white.
12. Move the LED0 slider to PWM0.
13. Move the LED0 Period slider to 0.033 seconds and the LED0 Duty Cycle to 14.45 %.
14. Observe the pattern displayed on by the RGB LED.
15. Move the LED1 Period slider to 0.296 seconds and the LED1 Duty Cycle to 12.11 %.
16. Move the LED1 slider to PWM1.
17. Observe the pattern being output on the RGB LED.
18. Observe LED 8 and LED 9, which individual blink/dim patterns generated by the LED0
19. To change the color displayed by the RGB LED, go back to the PCA9698 Bank0.
20. Turn off the green LED by selecting bit 2 HIGH.
21. Verify that the blink color is now mauve.
22. Turn off the red LED by selecting bit 1 HIGH.
23. Verify the blink color is now blue.
24. Slide the Period and Duty Cycle bars for the LED1 and LED0 and observe how the
The following exercise demonstrates how this is achieved.
1. Move the OE_Select jumper to the 3-4 position. The PCA9530 will now control the OE
2. Set-up the hardware and software as described in
3. Open the PCA9698 GUI.
4. In the ‘Device Configuration’ tab, select OE enable HIGH.
5. Select the Bank0 tab.
6. Enable the output for bits 1-3. These bits control the RGB LED on the board.
7. The RGB LED should be off.
8. Go to the ‘Device’ selection tab and select the ‘LED blinkers and Dimmers’ to select
9. Select the ‘Auto-write’ option.
