2011-05-22 17:00:43     Sharp LQ043T3DG01 driver availability

We are exploring the Sharp LQ043T3DG01 480 x 272, 3.5" landscape display to use with the BF527 based TLL6527M paltform. I saw there exists a driver for a similar LCD from SHARP LQ043T1DG01 for BF548.

 

The key difference between the two displays being the data interface, LQ043T3DG01 is 18 bit (can work with 565 RGB over PPI 16 bit mode, hence should work wih BF527) while the LQ043T3DG01 is 24 bit RGB hence current driver only works with BF548's EPPI port.

 

1. I was looking for suggestions on the best starting point for developing the driver for the 18 bit SHARP  LQ043T3DG01 480 x 272, 3.5" landscape display to be used with ADSP-BF527'sPPIport in16 bit mode. Should I start with the bf54x-lq043fb driver or the bfin-lq035q1-fb driver.

 

The 3.5" SHARP lcd driver is closer in terms of the 16 bit ppi interface used, the 4.3" sharp driver is similar in terms of display resolution but differs in PPI interface !

 

2. Has anyone already tried to interface LQ043T3DG01 over 16bit PPI with a Blackfin variant. Attached is the SHARP datasheet.

 

Regards

I think you may choose either and then begin to porting it to your own panel, anyway PPI is quite a flexible module and sometimes have to deal with the MMRs to get the desired output timming.

the BF52x does not have an EPPI, so picking any driver that is based on the EPPI doesnt make much sense (such as the bf54x-* driver).
