SPI_Glcd_Init
Prototype
void SPI_Glcd_Init(char DeviceAddress);
Description Initializes the Glcd module via SPI interface.
Parameters - DeviceAddress: SPI expander hardware address, see schematic at the bottom of this page
Returns Nothing.
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 dened before using this function.
The SPI module needs to be initialized. See SPIx_Init and SPIx_Init_Advanced routines.
Example
// Port Expander module connections
sbit SPExpanderRST at LATF0_bit;
sbit SPExpanderCS at LATF1_bit;
sbit SPExpanderRST_Direction at TRISF0_bit;
sbit SPExpanderCS_Direction at TRISF1_bit;
// End Port Expander module connections
...
// If Port Expander Library uses SPI module:
SPI1_Init(); // Initialize SPI module used with PortExpander
SPI_Glcd_Init(0);
Notes None.
