DLP4710 WITHOUT LED

Other Parts Discussed in Thread: DLP4710, DLP4710LC, DLPA3005, DLPC3479, DLPA3000, DLP4710EVM-LC

DLP4710 LC套件,在使用的过程中,不需要内置的光源,如何去掉这三个光源? 目前去掉LED,就无法正确投影图像。 是否可以通过在硬件上对PMIC管理芯片的反馈引脚做一定处理,如R595这个电阻的输入信号给特定信号,以避免外接光源? 还是在软件上,可以更新固件,不让PMIC检测LED开路的问题?

  在英文论坛搜到相关回答,但是找不到固件的资源和下载路径:

 

For the DLPC3479 chipset we allow multiple options (single option at a time).

you can pick any one below option depends on your requirement and design.

We could provide you the firmware based on your need :

1. No LED connected to DLPA3005

2. Any one LED connected to DLPA3005

3. Any two LEDs connected to DLPA3005

这是否是软件的一种解决办法?

谢谢!
