Hi All,

I'm using LPC1788 customized board with LCD connected thru 8bit parallel lines.

I want to connect LCD using EMI.

I'm doing the following configuration for EMC for CS3
**************< Code begin > *******************************
        TIM_TIMERCFG_Type TIM_ConfigStruct;
EMC_STATIC_MEM_Config_Type config;

        config.CSn = 3;
config.AddressMirror = 0;
config.ByteLane = 1;
config.DataWidth = 8;
config.ExtendedWait = 0;
config.PageMode = 0;
config.WaitWEn = 0;
config.WaitOEn = 0;
config.WaitWr = 0;
config.WaitPage = 0;
config.WaitRd = 0;
config.WaitTurn = 0;
StaticMem_Init(&config);

    // init timer
TIM_ConfigStruct.PrescaleOption = TIM_PRESCALE_USVAL;
TIM_ConfigStruct.PrescaleValue= 1;

// Set configuration for Tim_config and Tim_MatchConfig
TIM_Init(LPC_TIM0, TIM_TIMER_MODE,&TIM_ConfigStruct);
TIM_Waitms(100);

//delay time
TIM_Waitms(10);

    TIM_DeInit(LPC_TIM0);
**************< Code End > *******************************

For configuring the LCD driver the DCX,WEX,CSX control signals should be as same as shown in attached document.
A23 line is used as "LCD_DCX" signal, ( signal - "DNC_SCL" in the attached pic )
EMC_nOE is used as "LCD_RDX" signal, ( signal - "NRD_E" in the attached pic )
EMC_nWE is used as "LCD_WEX" signal, ( signal - "NWR_RNW" in the attached pic )
EMC_nCS3 is used as "LCD_CSX" signal, ( signal - "NCS" in the attached pic )
and I'm using
0x9c000000 and 0x9c800000 address for toggling "LCD_DCX" ( since it is connected to A23 line )

Please help me in configuring the EMC for the signal waveform as shown in attached snap.

Regards,
Shivaraj
