MEMLCD - Memory LCD#

Memory LCD interface.

The memory LCD interface is built to use SPI communication either with usart or eusart.

Configurations for three standard display are already supported (lpm013m126a, ls013b7dh03 and ls013b7dh06), but the sl_memlcd_t structure can also be configured with a custom LCD's specifications. To implement a fully custom memory LCD interface, see Custom Memory LCD.

Note

• When using the EUSART as the communication engine, care must be taken to ensure the EUSART is re-enabled when coming back from EM2/3. This is automatically handle by the Power Manager when added to a project. See EMLIB Eusart - EM2 guideline for non EM2-Capable instance

Custom Memory LCD#

The custom memory LCD is a module allowing the implementation of a LCD driver that can't use the already designed interface. To achieve this, conditions must be met.

The LCD driver and the communication need to be implemented manually. However, some functions must be implemented and the sl_memlcd_t structure must be initialized for the GLIB library to work properly. The functions to implement are sl_memlcd_init, sl_memlcd_power_on, sl_memlcd_draw and sl_memlcd_get and they must follow the same declaration as shown in the documentation.

In the sl_memlcd_init function, it is important to initialize a sl_memlcd_t type variable and fill in the "height" and "width" fields with the real specifications of the LCD display. This same variable must be accessible from the sl_memlcd_get function as the GLIB library will fetch the height and width of the display.

The sl_memlcd_t structure contains a "custom_data" field to store any custom structure needed for the implementation of the driver.
