Hi ,
LCD is connected to Renesas M30626 as extended memory, unfortunately i can't
get it to display anything. Connection is probably right, as the LCD is
answering to "status read" and also fills some commands. I got voltage
converter to run, but contrast regulator and bias voltages are not running.
Strange, that I have used LCDs with SID1565 and ST7565 controllers without
any problems, but now there is NJU6766 inside 51852. ( and yes, i know that
6766 require external resistors for contrast regulator).
Has someone suggestions how to correctly start-up this LCD ?

b. regards,
Raivo

I had the same problem and found that in addition to turn on the
display you must turn on the driver to get something on the display.
#define CONTROLLER_DRIVER_ON 0xE7 // Turns on the NJU6676 display
