void SPI_Glcd_Init(char DeviceAddress);
Returns Nothing.
Description
Initializes the Glcd module via SPI interface.
Parameters :
-
DeviceAddress: SPI expander hardware address, see schematic at
the bottom of this page
Requires
Global variables :
-
SPExpanderCS: Chip Select line
-
SPExpanderRST: Reset line
-
SPExpanderCS_Direction: Direction of the Chip Select pin
- SPExpanderRST_Direction: Direction of the Reset pin
must be defined before using this function.
The SPI module needs to be initialized. See SPI_Init and SPI_Init_Advanced
routines.
Example
// Port Expander module connections
sbit SPExpanderRST at PORTB.B0;
sbit SPExpanderCS at PORTB.B1;
sbit SPExpanderRST_Direction at DDRB.B0;
sbit SPExpanderCS_Direction at DDRB.B1;
// End Port Expander module connections
...
// If Port Expander Library uses SPI1 module :
SPI1_Init_Advanced(_SPI_MASTER, _SPI_FCY_DIV2, _SPI_CLK_HI_TRAIL-
ING); // Initialize SPI module used with PortExpander
SPI_Rd_Ptr = SPI1_Read; // Pass pointer to SPI
Read function of used SPI module
SPI_Glcd_Init(0);
