SPI_Lcd_Cong
SPI_Lcd_Out
Prototype
void SPI_Lcd_Cong(char DeviceAddress);
Description Initializes the Lcd 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 SPI1 module
SPI1_Init(); // Initialize SPI module used with PortExpander
SPI_Lcd_Cong(0); // initialize Lcd over SPI interface
Notes None.
Prototype
void SPI_Lcd_Out(char row, char column, char *text);
Description Prints text on the Lcd starting from specied position. Both string variables and literals can be passed
as a text.
Parameters - row: starting position row number
- column: starting position column number
- text: text to be written
Returns Nothing.
Requires Lcd needs to be initialized for SPI communication, see SPI_Lcd_Cong routine.
Example
// Write text “Hello!” on Lcd starting from row 1, column 3:
SPI_Lcd_Out(1, 3, “Hello!”);
Notes None.
