dlp light crafter

Other Parts Discussed in Thread: DLPC300

Hello ,

I want to control dlp light crafter 3000 through an external  microcontroller .   which kind of microcontroller can I use ?  

It  's possible to control   just the Driver board – includes the LED driver circuits, DLPC300 DMD Controller, power management circuits, and MSP430 Light engine – includes the optics, red, green, and blue LEDs, and the 608 x 684 diamond pixel 0.3- inch WVGA DMD of the card ? How could I proceed ?

Any help will be appreciated

Regards,

Hope

    Hello Hope,

    The LightCrafter 3000 EVM consists of the Systems board that has an applications processor (DM365) that configures the DLPC300 controller chip to send the data to DMD as well as the FPGA that also sits on the driver board which manages the the LED control signals going to the LED driver circuit and reading the images correctly from the frame buffer for the pattern sequence mode.

    We also provide a sample code that runs on DM365 to program and configure the controller in different modes for the video/pattern display. 

    You could use this applications processor already present as a part of the EVM (DM365) and runs linux to create your own application to control the DLPC300 chip.

    Could you give me more details on the application that you are planning to implement using a microcontroller/DM365 and stream data to the LightCrafter?

    Regards

    Hello ,

    Please I need some recomendations : in  my situation , I will communicate betwwen stm32f4 and dlp light crafetr instead PC/light crafter . So , how can I modify the sample code to be compatible with stm? How can I communicate between this two card ? ( Normally the path communication :  STM32-EThernet- Adaptator ethernet/usb) .

    How can I do ?

    Please need answer and thanks .

    Regards ,

    Hope

    Hello Hope,

    If you look at the API sample code, the commands are sent to the Lightcrafter over the RNDIS interface that is the I2C commands are enclosed in the TCP/IP packet format and sent over RNDIS USB interface.

    If you were to use the stm32f4 microcontroller, you will have to write your own application similar to the API sample code application to send the I2C commands enclosed in TCP/IP packet format over to Lightcrafter. These would then be converted to I2C by the code running on DM365 and sent to the controller chip on LightCrafter.

    Could you send me a friend request and I can work with you offline on this.

    Regards

    Hello Hope,

    Regarding your questions about being able to interface the LightCrafter with a microcontroller, we do not have any sample code specifically for interfacing with the microcontroller for your specific application and cannot offer that level of support.

    All the API sample code is available as a part of Software and Firmware Bundle 3.0 available on the product folder page.

    This sample code in conjunction with the Programmers Guide and DM365 Command interface guide all available on our DLP LightCrafter website should give you all the resources we make available for our customers to give them a starting point in interfacing their custom processors/chips with Lightcrafter and develop their own application.

    Hope this helps and good luck with your project.

    Regards

    Manasi
