DLPDLCR230NPEVM: Connecting directly to a PC/Mac

Part Number: DLPDLCR230NPEVM

Hi,

Is there any way to control this module directly from a PC or Mac, without using a raspberry Pi as an intermediary? I would like to use this as a screen almost. 

There are some ways to connect a PC/Mac to a GPIO (https://uk.pi-supply.com/products/ryanteck-rtk-gpio-pc-gpio-interface). How hard would it be to then send the i2c commands to the module?

I've been using the python scripts provided, but it is not clear how Pi-specific these are. Would they work if run then from a PC/Mac? If not, would it be hard to adapt the code?

Thanks in advance,

Dinis

    Hello Dinis,

    Welcome to the E2E forum and thank you for your interest in DLP technology!

    It is possible to send the commands to the EVM without a Raspberry Pi intermediary, however this is not a small task to undertake. The EVM is designed to be driven by a host processor (specifically a Raspberry Pi). Adapters would need to be purchased to allow your PC or Mac to interface with the EVM through the parallel data, I2C, SPI, sync, and projector control signals. This would be expensive compared to the price of Raspberry Pi and outside Texas Instruments' scope of support.

    The API provided on the DLPDLCR230NPEVM page is primarily meant for the EVM though it easily serves as an example to build scripts for other host processors. Cross examining dlpc343x_xpr4.py with the DLPC3436 Software Programmer's Guide should serve as a solid basis for building whatever API would be needed.

    Kind regards,

    Austin

    Thanks Austin! Raspberry Pi it is.
