DLP5530PGUQ1EVM: Application problems

Hi Yang,

Sorry for the delayed response due to July 4th holiday in the United States. What do you mean by embedded development board. Normally the EVM is meant to be used with a computer like a laptop or desktop.

Thanks,

Alex Chan

Hello Alex -

DlLP5530PGUQ1EVM is an automotive product. It is impossible to put a computer on the car,  so we need an embedded development board instead.

1）Do you have any similar applications for our reference?

2）Therefore, I may need a firmware that displays the external HDMI source by default after power on. Instead of modifying the display source by connecting the DLP control program settings on the computer.

3) Do you have a projection reflection film used with this EVM.

Thanks,

Hi Yang,

I can provide a baseline composer project and please add the following based on your system needs.

Before you do anything with firmware make sure you read the entire flash image currently on the EVM and also read the specific calibration data.

Set the following. The dimming level is the default dimming level on start up. 65535 being the brightest and remember the brightness on these systems are exponential. Next set some delay for the system to identify a connection. Then set the operating mode to display.

Pick the external video source you want as the default source and set the system to default to standby to give it time to make the connections. The above batch command sets will then switch the system to display automatically after the execution delay.

Then rebuild the entire project by clicking the two hammer icon at the top and this will create an output binary file in the folder of the composer project.

Flash that onto the EVM and then flash the calibration data you had read from the EVM beforehand.

For your other question regarding reflective screens we do not have much experience in that regards and do not have any we currently use with the EVM. We do have some recommendations for a supplier for a transmissive diffuser screen.

Thanks,

Alex Chan

Hello Alex -

Reflective film. Something like this:

Are there any recommendations?

Hi Yang,

By reflective film do you mean a reflective diffuser screen? Again TI only has experience in transmissive diffuser screens and does not have much experience related to reflective diffuser screens.

Thanks,

Hello Alex -

I want to connect EVM to HDMI of embedded Linux development board, but the embedded development board does not support the requirements of EVM.

Have you ever made any HDMI driver suitable for dlp5530pguq1evm?

Can you provide the source code and reference manual of the corresponding HDMI driver? Even the corresponding HDMI driver of windows system。

Because we don't have enough relevant information, it's difficult for us to develop applications.

I will be very grateful for any relevant information.

Thanks,

Hi Yang,

I am looking more into this sorry for the delay and thank you for your patience.

Thanks,
