Microcontroller Prototyping System: Platform and Components 8.4 MPS_CharacterLCD The MPS_CharacterLCD component provides a 2x80 character display window. Figure 8-3 shows the MPS_CharacterLCD component in System Canvas. This component is written in LISA. Figure 8-3 MPSVirtualisation component in sgcanvas 8.4.1 Ports Table 8-11 gives a brief description of the MPS_CharacterLCD component ports. Refer to the Microcontroller Prototyping System platform documentation for more details. See the Microcontroller Prototyping Board User Guide. Table 8-11 MPS_CharacterLCD component ports Name Port protocol Type Description display CharacterLCD master Provides content of alphanumeric display. intr Signal master Interrupt signal driven for display update. clock ClockSignal slave Reference clock. pvbus PVBus slave Slave port for connection to PV bus master/decoder. 8.4.2 Additional protocols The MPS_CharacterLCD component has one additional protocol. The protocols is: • CharacterLCD 8.4.3 Parameters The MPS_CharacterLCD component has no parameters. ARM DUI 0423J Copyright © 2008-2011 ARM. All rights reserved. 8-11 ID051811 Non-Confidential
Microcontroller Prototyping System: Platform and Components 8.4.4 Registers Table 8-12 provides a description of the configuration parameters for the MPS_CharacterLCD component. Register name Offset Access Description Table 8-12 MPS_CharacterLCD registers CHAR_COM 0x00 write Command register. The command set is compatible to the commands of the Hitachi HD44780U controller. CHAR_DAT 0x04 write Write data register. CHAR_RD 0x08 read Read data register. CHAR_RAW 0x0C read/write Raw interrupt. CHAR_MASK 0x10 read/write Interrupt mask. CHAR_STAT 0x14 read/write Masked interrupt. 8.4.5 Debug features The MPS_CharacterLCD component has no debug features. 8.4.6 Verification and testing The MPS_CharacterLCD component has been tested as part of the MPS example system using MPS test suites and by booting ucLinux. 8.4.7 Performance Applications that make heavy use of re-drawing the contents of the character LCD might incur an overhead through GUI interactions on the host OS. 8.4.8 Library dependencies The MPS_CharacterLCD component relies on the Simple DirectMedia Layer (SDL) libraries, specifically libSDL-1.2.so.0.11.2. This library is bundled with the Model Library and is also available as a rpm for Red Hat Enterprise Linux. See http://www.libsdl.org/ for more information on SDL.
