DLPC3479: Minimum value of Write RGB LED Max Current (5Ch)

Part Number: DLPC3479

Tool/software:

Hello TI contact,

I tried Green LED=0 and Blue LED = 0 of the Write RGB LED Max Current (5Ch) because green and blue LEDs are disable. However, Read RGB LED Max Current(5Dh) return both 91. Why does the case occur?

Regards,

Uryyyy

    Hello Uryyyy-san,

    The current 5Ch value does not control the LED being active. The lowest current for the LED to be reliably functioning is set as ~10% higher than the absolute lowest as this buffer removes some instability issues which are seen too close to the minimum activation of the LED.

    If you'd like a single LED active (Red), I would suggest you get the latest firmware labeled as 'RED_LED_ONLY.' This is found on the firmware selector page.

    Best,

    Aaron
