How to use the DEMO application
When the DPC utility starts, it will hide in the notification area (like below picture),
and double click the tray icon (shown as the red square below), 'DPC v3.0w.exe', it will show.
1. Frequency of panel selection
2. Confirm the panel which selected
3. If you choose to save DPC setting , the setting of frequency and duty cycle will be reserved.
4. It will show the MCU version of DPC.
5. Brightness control , you can choose : 10,20,30,40,50,60,70,80,90,100.
6. Show the brightness data which you choose.
7. When click the LightOff button , the panel will become darkest.
8. Record mouse position for go to 50 when LightOff. If click the button , 13 will show , you can click anywhere which you want for light on.
9. Record hotkey for go to 10 when LightOff. If click the button , The Record Hot Key window will show.
10. When click minimized , DPC will hide and show in the notification area.
11. Reset the record of hot key and position.
12. The light on mouse position and hotkay can not use together , after you record hotkey , you can't use the position anymore.
13. First key of hotkey
15. Second key of hotkey
16. Third key hotkey
17. Confirm the hotkey which you entered
18. Show hotkey which you set.
19. Hotkey will show here.
