sub procedure SPI_Lcd8_Config(dim DeviceAddress as byte)
Returns Nothing.
Description
Initializes the Lcd 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.
SPI module needs to be initialized. See SPI1_Init and SPI1_Init_Advanced routines.
Example
' port expander pinout definition
dim SPExpanderCS as sbit at PORTB.B1
SPExpanderRST as sbit at PORTB.B0
SPExpanderCS_Direction as sbit at DDRB.B1
SPExpanderRST_Direction as sbit at DDRB.B0
...
Spi1_Init() ' Initialize spi
interface
Spi_Rd_Ptr = @SPI1_Read ' Pass pointer to
SPI Read function of used SPI module
SPI_Lcd8_Config(0) ' Intialize lcd in
8bit mode via spi
