DLPA3005: dlpa3005+dlpc3439+dlp4710

Part Number: DLPA3005
Other Parts Discussed in Thread: DLPC3439, DLPC3479, DLP4710LC

目前 dlpa3005 的VOFS    VBIAS   VRST,电压都正常,INTZ 和RESET_Z都为高电平,各个低压值都正常,从机dlpc3439的HOST_IRQ上电拉高后几秒后拉低,初始化成功,但是主机dlpc3439的HOST_IRQ一直为高电平;ILLUM_SW也没有电压,只有1V的左右。

问:1.LED_ANODE提供给LED的电源如何才能有?

        2.主机dlpc3439的HOST_IRQ一直为低,其他信号都在正常,还有哪些地方会造成初始化失败?
