关于DLP4500应用的几个问题

1. 对的.可以调整的,曝光时间.

2. 在user guide http://www.ti.com/lit/pdf/dlpu010 第62页有详细配置的.

vsync, the maximum exposure time is 16667 ÷ 3.
0x1A29
6. Set up the LUT.
(a) Open mailbox: send command 0x1A33 with data byte 0x02 for LUT
(b) Set mailbox offset: send command 0x1A32
(c) Fill pattern data: send command 0x1A34 with:
(i) Byte 0, b1:0, choose trigger. The first pattern in the sequence should have an external positive
trigger. The next patterns in the sequence should be set to the continuous trigger.
(ii) Byte 0, b7:2, choose pattern number (what bit planes will be illuminated). Max is 24 for 1 bitdepth
(iii) Byte 1, b3:0, choose bit weight (1 to 8)
(iv) Byte 1, b6:4, choose which LEDs are on (blue, green, red)
(v) Byte 2
(i) b0: invert pattern if 1
(ii) b1: insert black pattern after current pattern if 1 (should be 0 if continuous trigger)
(iii) b2: perform buffer swap if 1 (this should be done at every external positive trigger in
streaming mode)
(iv) b3: trigger out1 stays high (if this stays high for n patterns, then exposure time is shared
between n patterns)
(vi) Repeat the steps in 6c (fill pattern data) for each pattern in the sequence
(d) The LUT for this example is: 0x62101 0x21107 0x0410B 0x8110B 0xA210B 0x27117 0x41119
0x8311B 0x27123 0x02127 0x84127 0x2612F 0x61131
(e) Close mailbox: send command 0x1A33 with data byte 0x00
7. Execute the Validate command: send 0x1A1A
8. Read statuses: send commands 0x1A0A, 0x1A0B, and 0x1A0C
9. If the Validate or Status commands show an error, change the system configuration to remove the
error.
10. Start the pattern sequence, either with TRIG_IN_2 or 0x1A24.

3. 0x1A29

使用GUI配置比较方便.上面的是LUT详细设置.
