DLPC3470: Firmware for 2500Hz external pattern mode needed

Hello and thank you.

These will require further clarifications:

1) I do have the DLP2010 Lightcrafter EVM, however the DLPC chip on it is the cheaper DLPC3435, not 3470, which I believe does not support this high framerate monochrome streaming. So I don't think the EVM can be used for testing. Please confirm.

2) I understand the DLPC can be programmed, my question is if I want the end user to be able to switch between an lower fps RGB projection streaming mode and high fps monochrome streaming mode, can this be done by one firmware and a simple command to the DLPC from ,say, a switch button on the device, or will our board need to essentially reflash the DLPC with the appropriate firmware each time the user switches from one mode to the other?

3) I understand 104.2 is the upper limit, my question was whether your team had checked that a standard GPU can support non-whole number framerates (eg. 104.2 vs 104)? I know Nvidia supports non-standard (not 30, 60, 120, 144 or 240) framerates so a GPU from the last few years will support 104 fps, but I don't know if it will support 104.2 and I hoped you would know by having tested this. The difference is 4 monochrome frames less, but still important enough for my project for me to ask.

Thank you.

1) Is there a GUI tool for specifying firmware parameters and flashing the Lightcrafter DLPC3470? Or is there no need since the one stock Firmware can be used for any mode as long as it is set by an i2C command?

2) Is it possible to modulate more than one LED at the same time with that Lightcrafter in binary mode to get yellow color or white binary projection?

I see. Regarding point 2 which workaround would you suggest?

1) I think we can have custom circuitry after the PMIC to branch out the LED powering lane into 3 and readjust the voltage and current for each LED accordingly while having the PMIC generate the correct pulses.

2) Have a separate DLPA2005 for each LED somehow

3) Have a triple dye LED emitting all the color channels (not aware of any in the market with a single positive and negative pins for the three dyes)


Also, are the 1) optical design files for this Lightcrafter publicly available for editing and 2) Are the PCB design files for this Lightcrafter available for editing in Altium or Eagle format?

I understand the optical design of the Lighcrafter will not work with a different LED. I was talking about the chipset and custom optical engine using the DLP2010. Any info about the questions I asked regarding the chipset, not the EVM, is greatly appreciated.

And thank you for the link to the electrical design files, but you seem to have mis-linked as it leads me to the 3010 EVM design, not 2010.

Thank you.
