Just download the datasheet of a candidate controller, and see if all the commands you found have a correct meaning. Since the lcd_init_device has a lot of commands I think the quick way to match one controller is to look at lcd_write_reg or LCD_FB_BASE_REG (device framebuffer). - -- Rafaël Carré -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAko997QACgkQYWCeGMCv8Q+XNQCgzYrLV8exdwvxaYQ9HJYy2bb5 qYAAn24LJFd7hT2mvewGXmMS7V74dlmQ =ECEy -----END PGP SIGNATURE-----
