Direct Drive LCD Design Guide

 

 

The LCD Direct Driver is configured to operate with a given hardware platform by setting macro definitions.  
These values will have to be determined from the schematics on the hardware platform. As an example, 
the demonstration code can be compared the LCD direct drive hardware schematics. 

2.6.1 

This is the numeric value of the CS pin used for the frame buffer, for example if CS2 is used, a value of “2” 
would be entered. 

2.6.2 

Enter the number of BCLK cycles that are required to access the frame RAM (only used in SRAM 
configurations). 

2.6.3 

Enter the configured CAS latency for the SDRAM (only used in SDRAM configurations). 

2.6.4 

Enter the SDRAM page size in words (only used in SDRAM configurations). 

2.6.5 

Enter the name of the ExDMAC being used for the LCD Direct Drive. For example, if ExDMAC channel 2 
is being used, set the value to “EXDMAC2”. 

2.6.6 

Enter the associated port for the requested signal mapping. For example if the LCD_BACKLIGHT is on 
port PM1, set the port value to “M”. 

2.6.7 

Enter the associated port for the requested signal mapping. For example if the LCD_BACKLIGHT is on 
port PM1, set the pin value to “1”. 

2.6.8 

Enter the SFR field for the associated interrupt controller peripheral. For example if the H8SX ExDMAC 2 
is being used, enter “INTC.IPRJ.BIT._EXDMAC2”. 

2.6.9 

Enter the interrupt vector number for the associated peripheral. For example if the H8SX ExDMAC 2 is 
being used, enter “142”.
