Other Parts Discussed in Thread: DS90UB948-Q1EVM, ALP

Hi,

Now I use DS90UB947-Q1EVM & DS90UB948-Q1EVM first and want to show image to LCD panel(1280*800). The block is as below.

Do I need to setup any register to UB947 or UB948?

Does it have any document or simple example for our reference first?

Thanks.

Best Regards,

Eric

Eric,
You can review the DS90UB947 and 948 EVM user guides for the board set up and ALP tool instructions. You do not need any special register writes to bring up the link.

1. ALP is one GUI tool, you can get the function menu and the reg. setting in ALP tool
2. pls check the EVM board user guide, which has how to install ALP and use ALP.

Hi Stevn,
Yes, I know this and also already enable BIST mode to show the Color pattern to LCD Panel.
But Now use External Video signal through DS90UB947 --> FPD Link Cable --> DS90UB948 --> LCD Panel (1280*800).
How can I process this setting at DS90UB947 or DS90UB948?
Please kindly provide your suggestion for reference.
Thanks.

Best Regards,
Eric

Hi Steven,
I mean the display function OK at BIST mode by using internal pattern throught ALP tool between 947 to 948.
Now I use external Video signal into DS90UB947EVM but no any image dispaly on LCD panel.
I think if should to do some setting on DS90UB948, right?
If you have suggestion for our check again?
Thanks.

Eric,
pls check the mode setting of UB947 and UB948, especially on the mode_sel0 setting, the MAP_SEL in d/s is typo (0 and 1 is exchanged).

regards,
Steven
