Hello,

Many thanks for library.

Just little feedback:
I have tested the saintsmart shield with the demo of arduino code, works.
I have tested (only display), the code @ Nov 06, 2016 12:21 am, works.
I have create new shield using the same schematic of saintsmart*, i have just added FET for backlight.
I test my new shield with arduino demo code, works.
I test with code @ Nov 06, 2016 12:21 am, not works !!!!
I have modified the library with the code from last post mkcreta, it's works.

Thanks
Olivier
* Stupid shield, not possible to get orther port....

Hello,
just trying to program a SSD1963-display with resolution 480x272 with a shield for a Arduino-mega2560 board using BASCOM and the 2014-version of the library.

Just shows nothing on the display.

Does anybody have the init-sequence with all the values for PLL and Synch for the resolution?
Would help I think...

Greetings, Ernst

Hello Ernst,

This is successful for the PLL

Code:
   Res_disp = 0 : Waitms 10 : Res_disp = 1 : Waitms 10      'Reset Display

   Call Ssd1963_select_reg(&He2)                            'PLL multiplier
        Call Ssd1963_write_data(24)                         'M = 24
        Call Ssd1963_write_data(&B001_01011)                'N = 11
        Call Ssd1963_write_data(&B00000_1_00)               'Execute setting PLL    final setting is 250/12 = 20.83 MHz
                                                            'This seems to be the lowest PLL without flickering
        Call Ssd1963_write_data(&H54)                       '54 = dummy

   Call Ssd1963_select_reg(&He0)                            'E0
        Call Ssd1963_write_data(&H01)                       'start PLL
        Waitus 200
   
   Call Ssd1963_select_reg(&He0)                            'E0
        Call Ssd1963_write_data(&H03)                       'LOCK PLL

   Call Ssd1963_select_reg(&H01)                            'Software reset

   Waitms 100
 


Regarding the "Synch", let me know which register you need and I will post it.
