Hi,

 

Did anyone used LCD with DE signal with BF527 processor? will this be possible with BF527 processor?

 

The signals description is below.

 

            PPI_FS1  -->   HSYNC

 

            PPI_FS2  -->   VSYNC

 

            with DE pin

 

while searching the forum i come across this thread? the timing diagram for my lcd is similar to the one which is attached in this thread.

Please provide your suggestions.

 

Thanks in advance, Sreedhar.

the only BF527 we've done an LCD with is the one on the bf527-ezkit.  you can find the schematics for that on analog.com.

Dear Mike,

 

Thank you very much.

 

Similar kind of LCD with DE signal usage is done on any processor? any EZkit has this kind of LCD.

 

So that I can have some reference driver available in the distribution.

 

Thank you.
