Other Parts Discussed in Thread: SN65DSI83,
Tool/software: Linux
Hello Support team,
We are working on one product design, where we need help from your side.
For this product, we are using SN65DSI83 for DSI-to-LVDS output and the output from SN65DSI83 is given to DLPC6401.
1. For the video parameters like Horizontal, Vertical Sync, etc... we need to set these parameters according to DLPC6401 controller for resolution of 1280*800.
We set the video parameters as follows :
1. CHA_ACTIVE_LINE_LENGTH = 1280 or 0x500
2. CHA_VERTICAL_DISPLAY_SIZE = 800 or 0x320
3. CHA_HSYNC_PULSE_WIDTH = 80 or 0x050
4. CHA_VSYNC_PULSE_WIDTH = 9
5. CHA_SYNC_DELAY = 32
6. CHA_HORIZONTAL_BACK_PORCH = 40
7. CHA_VERTICAL_BACK_PORCH = 7
8. CHA_HORIZONTAL_FRONT_PORCH = 40
9. CHA_VERTICAL_FRONT_PORCH = 7
10. LVDS_CLK_RANGE = 62 MHz to 87.5 MHz
11. DSI_CLK_DIVIDER = 3
12. CHA_DSI_LANES = 4
13. CHA_DSI_CLK_RANGE = 430 to 435 MHz
14. CHA_24BPP_MODE = 24bpp mode (format 2)
but in DLPC6401 data sheet -Section 7.3.1.5 they have mentioned different data for video parameters.
So we need to know about video parameters for 1280 x 800 resolution that we have to configured to send data to DLPC6401 controller.
1. Horizontal and Vertical Sync Pulse
2. Sync Delay for Horizontal and Vertical Sync
3. Front and Back porch for Horizontal and Vertical Sync
