Dear All,
I am trying to interface ST7567 based graphical lcd-tms320f28377s TG12864H3-03A EN_V1.1.pdf. I inteface this lcd with tms320 with prallel connection and it is working fine. But when I try SPI interface (using software spi) then display not showing any thing. I connect LCD in four wire mode usng MOSI, SCLK,CS, RS (A0). As given in data sheet(please see the attachment). And my code is as follow. I connect mosi on d7 and sclk on d6 as given in st7567 controller data sheet. Other connection are also correct. I think there is problem in initilization of lcd
