4.3.2 DLP9000X (2560 x 1600) User Image Display Example (Global)

The following steps describe how to display an image on a DLP9000X or DLP9000XUV DMD:

Send the Buffer Data from the PC to the Apps FPGA

Step Description Register Address Data
1 Set Apps FPGA user load mode (all zeros) 0x0040 enable bit = '0'
2 Set buffer starting write to zeros and number of rows to 1600 (0x640) 0x0024 0x640
3 Send the WQXGA image to the user image buffer.

This requires 1000 write bursts (FIFO Write Transaction)
Burst 1 256, 16-bit words
Burst 2 256, 16-bit words
⁞
Burst n 256, 16-bit words
⁞
Burst 1000 256, 16-bit words

Send Data from the Apps FPGA Data Buffer to the DLPC910 - DMD

Set image data modifiers if needed (ns_flip, comp_data). Use dip switch (SW2) on DLPLCRC910EVM board or use register 0x0010.

Step Description Register Address Data
1 Send first row of data to DLPC910 - DMD 0x002C 0x00000003
2 Send the remaining 1599 rows 0x002C 0x063F0001
3 Issue a global mirror reset to DLPC910 - DMD 0x0030 0x00000183
