DLPC230-Q1: Request for DLP5533A-Q1 + DLPC230-Q1 + TPS99001-Q1 Automotive Headlight Development Resources

Huang San — Mon, 17 Aug 2026 02:02:39 GMT

Part Number: DLPC230-Q1
Other Parts Discussed in Thread: TPS99001-Q1, , DLP5533A-Q1, DLP5531A-Q1

Hello,

I am a graduate student at a university and am currently conducting academic research on an automotive ADB (Adaptive Driving Beam) headlight system based on DLP5533A-Q1 + DLPC230-Q1 + TPS99001-Q1. The project is for university research and educational purposes only.

I have already reviewed the publicly available TI resources, including the DLP5533A-Q1, DLPC230-Q1 and TPS99001-Q1 datasheets, the DLPC230 Programmer's Guide, DLPC230 Control Program Lite, and the related Headlight reference resources in TI Resource Explorer.

To complete the bring-up, Flash image generation and programming of our custom hardware, I would like to request access to the following resources:

DLP Composer for Automotive
DLP Composer for Automotive Project Files
Reference project/configuration files for DLP5533A-Q1 + DLPC230-Q1 + TPS99001-Q1 Headlight
The corresponding DMD Configuration, Sequencer, TPS99001 Configuration, and recommended DLPC23x software/firmware release

If a dedicated DLP5533A-Q1 project is not available, I would also appreciate access to the DLP5531A-Q1 + DLPC230-Q1 + TPS99001-Q1 Headlight project, together with guidance on which configurations must be changed for DLP5533A-Q1.

These resources will be used solely for university research, learning, and experimental validation.

Thank you for your support.

DLP991U: DMD产品选型：尽可能多的像素数和尽可能高的刷新率

Part Number: DLP991U

Dear TI Teams,

您好，我司想要采购DMD，需要尽可能多的像素数和尽可能高的刷新率。
我看到官网上在400-700nm波段有4K的DLP991U可供选择，请问：
1. 像素数有无更高的DMD阵列如8K？
2. 刷新率有无尽可能快的DMD如百微秒量级？(区分局部刷新率和全局刷新率)

感谢帮助

DLPC350: I'm not quite clear about the meanings of different trigger modes in the pattern mode of the DLPC350. I would like to seek your advice on this.

Part Number: DLPC350
Other Parts Discussed in Thread: DLP4500

Dear TI Technical Expert!
In the pattern mode of dlpc350, the trigger modes include trigger mode 0, trigger mode 1, and trigger mode 2.
We are engaged in industrial-grade 3D scanning applications. The requirement is: to reliably update and project the pattern through an external control signal, and achieve precise coordination with the camera's photography, so as to achieve the most optimized photography and acquisition of the projected pattern.
Under such requirements, may I ask:
1. Is it better to use trigger mode 0 or trigger mode 1? Or can both modes achieve the same effect well? Why?
2. In trigger mode 0, is VSYNC considered an external trigger signal or an internal trigger signal? Is the function of VSYNC the same as TRIG_IN_1 in trigger mode 1, which is to advance to the next pattern?
For the register (I2C: 0x78), does bit[1:0] of byte0 select b00 = Internal or can it choose b01 = External positive or b10 = External negative or b11 = No input trigger (continue from previous; the pattern still has full exposure time)? What does selecting b00 = Internal specifically refer to? Is it the internal trigger, VSYNC, or the register writing? When can b11 = No input trigger be selected?
Can TRIG_OUT_1 be used to provide exposure for camera shooting?
In Table 4-2. Trigger Mode 0 Example of the document DLPU010G, is the setting of registers 0x77, 0x76, 0x78 only applicable if using images from flash memory? If not using images from flash memory, are the registers 0x77, 0x76, 0x78 not set?
Does this Table 4-2. Trigger Mode 0 Example mean that while inputting a pattern through the RGB channels, it is also possible to read the images stored in the flash memory simultaneously? How can this be done, and how is the timing of the projection of different sources of pattern patterns controlled?
If VSYNC is controlled by FPGA logic, can the pattern images be precisely controlled to change by using the rising and falling of VSYNC? Or is VSYNC like a video stream, only being a fixed period signal and not easily changing the period value? What are its limitations?
3. In trigger mode 1, is it through TRIG_IN_1 to control the replacement of the pattern, and through TRIG_IN_2 to achieve the stable display of the pattern (by projecting the pattern through DLP)?
Is the display of the pattern by DLP4500 a simultaneous flipping of all related mirrors, or a line-by-line flipping?
Due to the urgency of the project, we hope to receive a reply as soon as possible!

DLPC350: DLPU010G regarding "pattern exposure time" and "frame period" seems to have inconsistent statements. What is the relationship between them?

yongning chen — Thu, 30 Jul 2026 13:17:42 GMT

Part Number: DLPC350

Dear Technical Expert!

In the document DLPU010G – May 2013 – Revised July 2018, on page 48 of the description of the dlp0x66 register, in the external video input pattern sequence modes, the pattern exposure time must be equal to the frame period.
However, on page 61, in Table 4-2. Trigger Mode 0 Example, for register 0x66, Set the exposure and frame rate (4 bytes for each) so that the time between vsync triggers will allow three patterns to be shown For example,
for a 60-Hz vsync, the maximum exposure time is 16667 ÷ 3.
These two points are clearly in conflict. On page 48, it states that the pattern exposure time must be equal to the frame period. However, on page 61, it says that the time between vsync triggers will allow three patterns to be displayed.
Is "the frame period" here referring to the frame period of VSYNC?
We input the pattern through RGB, and select an 8-bit pattern. Then we have pattern num 1 (green 8-bit), pattern num 2 (red 8-bit), and pattern num 3 (blue 8-bit). In this case, what is the relationship between the pattern exposure time and the frame period? How should the register 0x66 be set?
If the frame period of VSYNC is 12000us, should the pattern exposure time be set to 4000us or 12000us?
How can we project 3 pattern patterns within one VSYNC frame period? These three pattern patterns correspond to the pattern num 1, pattern num 2, and pattern num 3 described in Table 2-70 of Document DLPU010G?
In the above situation, how should the registers 0x75 and 0x78 be set?

Due to the urgency of the project, we hope to receive a reply as soon as possible!

DLPC350: DLPC350: The projection design using dlpc350 + DLP4500, with pattern mode and trigger mode 0, fails the register design verification. What could be the reason?

yongning chen — Thu, 30 Jul 2026 12:37:04 GMT

Part Number: DLPC350
Other Parts Discussed in Thread: DLP4500,

Dear TI expert!

We are using the DLPC350 + DLP4500 for projection design, with the following requirements:
Input graphics via RGB interface only throughout the entire process. Select trigger mode 0, VSYNC triggering, 8-bit pattern, and a total of 3 patterns. The VSYNC period is 16,080 μs.
We expect to output three patterns within one VSYNC cycle. These three patterns correspond respectively to the graphic data inputs of the RGB channels. All three patterns have the same exposure time and are triggered identically by VSYNC.
Our register settings are as follows:

#Write: Set the display mode to pattern display
W 0x34 0x69|0x80 0x01

# Write: Stop Sequence (Display if running)
W 0x34 0x65|0x80 0x00

W 0x34 0x6f|0x80 0x00

#Write: Set mode number 1 - Mode

#Write: Set mode trigger mode - 0

#Write: Exposure Time

#Write: Set Pat LUT

W 0x34 0x7D|0x80 0x00

# Add validation to complete delay or polling status

#Write: Start pattern sequence
W 0x34 0x65|0x80 0x02

After completing the above register settings, we found that the read value of register 0x7D is 0x01. What could be the cause of this issue, and how can it be resolved?

One more point to add: The video stream of the RGB channels we input to the dlpc350 is FPGA-simulated. During the DE active period, the resolution is 1280x800, the data clock of RGB is 72 MHz, and the VSYNC period = 1340x862/72 = 16080 us.

Looking forward to your reply!
