The module has been designed to support multiple LCD targets. Each target has a specific configuration and have been provided with the component int the /devices directory. The module only supports a single LCD target per XCore.

To select the target the following should be done:

If the required target is the part AT043TN24V7 LCD display then,

• Create a header in the application project called lcd_conf.h
• In the lcd_conf.h add the define #define LCD_PART_NUMBER AT043TN24V7. This will include the “lcd_defines_AT043TN24V7.h” required for the selected target.
• Any specific overrides should be added to the lcd_conf.h. For example, to override the LCD_HEIGHT to 600 pixels add the line #define LCD_HEIGHT 600.
• The application should also include the port mapping for the LCD as per the hardware used. A variable of the type structure lcd_ports should be created and must include the port information

Example: In the application file

struct lcd_ports lcd_ports = {
        XS1_PORT_1G,
        XS1_PORT_1F,
        XS1_PORT_16A,
        XS1_PORT_1B,
        XS1_PORT_1C,
        XS1_CLKBLK_1
};

The declared variable lcd_ports is used by the LCD server call to address these ports. A core should have the lcd_server running on it and it should be connected by a channel to the application, for example:

chan c_lcd;
par {
      lcd_server(c_lcd, lcd_ports);
      application(c_lcd);
}

The module by itself cannot be build or executed separately. It must be linked in to an application which needs LCD display. Once the module is linked to the application, the application can be built and tested for driving a LCD screen.

The following should be done in order to link the component to the application project

1. The module name module_lcd should be added to the list of MODULES in the application project build options.
2. Now the module is linked to the application and can be directly used

The module is built on XDE Tool version 12.0 The module can be used in version 12.0 or any higher version of xTIMEcomposer.

The modules have been designed to support two types of interfacing with the touch screen controller; one for direct interfacing and the other for interfacing through a server. Only one of these two modules should be used by the application program.

To use a module,

• Create a header file in the application project called touch_lib_conf.h or touch_server_conf.h.
• In the header file, add the defines for conditional compilation and device-specific parameters.
• The application should also include the port mapping for the touch screen controller. A variable of the type structure touch_controller_ports should be created and must include the port information.

Example: In the application file

struct touch_controller_ports ports = {
        XS1_PORT_1E,
        XS1_PORT_1H,
        1000,
        XS1_PORT_1D
};

When module_touch_controller_server is used, a core should have the touch_controller_server running on it and it should be connected by a channel to the application, for example:

chan c;
par {
      touch_controller_server(c, ports);
      app(c);
}

The touch controller module by itself cannot be built or executed separately. It must be linked into an application. The application also depends on I2C module. Once the modules are linked to the application, the application can be built and run.

The following should be done in order to link the modules to the application project.

1. The module name module_touch_controller_lib or module_touch_controller_server should be added to the list of MODULES in the application project build options.
2. The module name module_i2c_master should also be added.
3. Now the modules are linked to the application and can be directly used

The modules are built on XDE Tool version 12.0 The modules can be used in version 12.0 or any higher version of xTIMEcomposer.
