TFT_Set_Active

Prototype

sub procedure TFT_Set_Active(dim Set_Index_Ptr as ^TTFT_Set_Index_Ptr, dim

Write_Command_Ptr as ^TTFT_Write_Command_Ptr, dim Write_Data_Ptr as ^TTFT_

Write_Data_Ptr)

Returns

Nothing

Description This function sets appropriate pointers to a user-defined basic routines in order to enable multiple

working modes.

Parameters:

Set_Index_Ptr

: Set_Index handler.

Write_Command_Ptr

: _Write_Command handler.

Write_Data_Ptr

: Write_Data handler.

Requires

None.

Example

‘ Example of establishing 16-bit communication between TFT display and

PORTD, PORTE of MCU :

sub procedure Set_Index(dim index as byte)

TFT_RS = 0

Lo(LATD) = index

TFT_WR = 0

TFT_WR = 1

end sub

sub procedure Write_Command(dim cmd as byte)

TFT_RS = 1

Lo(LATD) = cmd

TFT_WR = 0

TFT_WR = 1

end sub

sub procedure Write_Data(dim _data as byte)

TFT_RS = 1

Lo(LATE) = Hi(_data)

Lo(LATD) = Lo(_data)

TFT_WR = 0

TFT_WR = 1

end sub

main :

TRISE = 0

TRISD = 0

TFT_Set_Active(Set_Index,Write_Command,Write_Data)

TFT_Init(320, 240)

.....

end.
