用i2c方式对dlp350进行pattern sequence创建时,在0x78这个地址多次写入是不是把前一次写入的命令弄丢了,还怎么创建多个pattern,前面创建那个image index怎么也是往0x78中写命令?这个不太理解,请教一下

请提供firmware和具体要求是怎样的?都是8BIT pattern吗?
是内部触发还是外部?和pattern在Flash Image Index对应关系.选择什么色彩?(RGB LED ON)
曝光时间.
1. Byte 0, b1:0, choose trigger: internal
(0x00), external positive (0x01), external
negative (0x02), continue from previous
(0x03)
2. Byte 0, b7:2, choose pattern number
(what bit planes will be illuminated). Max
is 24 for 1 bit-depth
3. Byte 1, b3:0, choose bit weight (1 to 8)
4. Byte 1, b6:4, choose which LEDs are on
(blue, green, red)
5. Byte 2:
(a) b0: Invert pattern if 1
(b) b1: Insert black pattern after current
pattern if 1 (should be 0 if continuous
trigger)
(c) b2: Perform buffer swap if 1
(d) b3: Trigger out1 stays high (if this
stays high for n patterns, then
exposure time
jeremy ,我仔细看了那个program guide,但是还是没有搞清楚,你方便给我私发一下联系方式吗,还想请教一些这方面的知识。我邮箱825729001@qq.com
再举例我写的方式:创建两个pattern,连续写入的数据为(0x00, 0x48, 0x00,0x04, 0x28, 0x00),我想实现的是第一个pattern,index 位置0,内触发方式,bit weight为8,LED on为blue,byte2都为0,第二个pattern,index 位置为1,内触发方式,bit weight为8,LED on为green,byte2都为0。不知道我的理解对不对?
对的,在配置LUT的之前,需要配置pattern mode和LUT mailbox.
