  • DLPC1438: Issue of Data transfer to the DLPC1438

    Part Number: DLPC1438 Tool/software: Using SPI sent .bmp Data to the DLPC1438 over and over, sometimes(atleast 10 hours) it would happen spi ready keep low for certain seconds(16~30) while one .bmp file just cost 2 seconds sent to DLPC1438 in normal.…

  • DLPC1438: DLPC1438 after setting the PROJ_On signal to high, the HOST_IRQ signal stays high.

    Part Number: DLPC1438 Other Parts Discussed in Thread: DLPA3005 , Tool/software: Hi I have a board with DLPC1438 and DLPA3005. The problem is that after setting the PROJ_On signal to high, the HOST_IRQ signal stays high. The DMD cable and LEDs are connected…

  • DLPC1438: How to show the splash pattern?

    Part Number: DLPC1438 Tool/software: How to show the splash pattern? I used the 9.5.1 project file and change the splash pattern to a resolution 1280 x 720 png file then build the image file. After load the image file to the Light Engine, I used composer…

  • DLPC1438: The FPGA_RDY signal goes high with some noise after Proj_On

    Part Number: DLPC1438 Tool/software: I have a board with DLPC1438 and PHK1438-EP4CE15M9C7N. The problem is that after setting the PROJ_On signal to high.The FPGA_RDY signal goes high but there are some noise like picture 1. When the temperature get a…

  • DLPC1438: How to print the 1280 x 720 pattern from spi interface

    Part Number: DLPC1438 Tool/software: How to print the 1280 x 720 pattern from spi interface? I can successfully print the 2560 x 1440 pattern, and just modify the parameter of the spi format(like column start index : 5, column end index : 14,start row…

  • DLPC1438: Solve the issue of SPI Ready Status Keeping Low

    Part Number: DLPC1438 Tool/software: Is any other way to solve the spi ready status keep low ? Is it possible that use the Standby Mode command to recover it ? We check that we sent the correct data to the 1438, but sometimes would happen the spi…

  • [FAQ] DLPC1438: Python Script Example for DLPC1438 CRC16 Calculation

    Part Number: DLPC1438 Clientele may find it difficult to properly format and send the incoming SPI data for CRC16 calculation on a DLPC143x system. Section 4.2 of the DLPC1438 Software Programmer's Guide discusses this procedure, however, we have included…

    TI Thinks Resolved
    Part Number: DLPC1438 Other Parts Discussed in Thread: DLPA2005 , , DLP300S Hello, I'm trying to make sense of the DLPC1438 way of controlling the light which uses dark frames and exposure frames and in general of the DLPC1438 + DLP300S + DLPA2005 combination…

  • DLPC1438: Display at native resolution of 300S?

    TI Thinks Resolved
    Part Number: DLPC1438 I am using SPI to send 1280x720 frame data, but am struggling to get it to output in native resolution. So far it just displays 1/4 of the 2560x1440 frame. I assume because the actuator is on by default? What commands do I need…
