I2C .C; Lcd .C - Fujitsu MB2146-450-E Setup Manual

4.2.5 I2C .c

In this function, we should initialize I2C status and use SCL and SDA to send data to master
device and receive data from slave device.
Following table describes the I2C library:
Function Name
unsigned char RD_I2C( unsigned char
Main_Addr, unsigned char Sub_Addr )
void Write_I2C_Proc(unsigned char
MainAddr, unsigned char SubAddr, unsigned
char I2Cdata)
Following table describes how to use these functions.
Type
Read data RD_I2C(0xa0,0x01);
Write data to
Write_I2C_Proc(0xa0,0x01,0x25);
EEPROM

4.2.6 LCD .c

In this function, we should initialize LCD register and drive LCD by sending different data to
SEG00...SEG31
Following table describes the LCD library:
Function Name
void Init_LCD(void)
void LCD_Clear(void)
void LCD_LigON_NUM(unsigned char Num,
unsigned char Dat)
Following table describes how to use these functions.
Type
Display LCD LCD_LigON_NUM(0x02,0x06);
