LCD

The MSE-Embedded platform contains one LCD as indicated in the below figure.

The MSE-Embedded board contains a RGB LCD 320*240 pixels. The datasheets can be found here.

The control pins of this LCD which are connected to the FPGA are listed in the table below. An example tcl-file that can be used with Quartus can be found here.

The initialization code that can be used with the Nios can be found here (lcd_simple.c) and here (lcd_simple.h).

When choosing 8bit mode (IM0 = 1) use DATA8 - DATA15 as data bus and set DATA0 - DATA7 to 0. In 16-bit mode (IM0 = 0) use DATA0 - DATA15.
