Precise Brightness Control - BOPIXEL OPR407 Series Operating Manual

4.6.1 Precise brightness control

In the "Illumination" option, you can click the "Get" button under "Rgb led
enable" to get the light source that is now turned on. Click "Get" under "Rgb led
current" to get the brightness values.
Take the module of Q7LED light source as an example. The maximum output
current of its drive circuit is 6A, and the maximum brightness ("Rgb led current")
value displayed is 1023. The current increase corresponding to each increase of the
brightness value by 1 is 6000mA/1024=5.86mA.The maximum current that Q7 LED
can accept is 5A， The corresponding brightness value is 5000mA/5.86mA=853. If you
want to set the blue LED current to 2A, then calculate 2000mA/5.86mA=341. Enter
341 in the box behind the blue led current and click the "Set" button to complete the
setting.
