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
