Dear all,
after building RS232 interface in my LCD module, I wanna build I2C and SPI interfaces into it as well, is there any friend who can give me the suggestion about the code for those two interfaces.
As the codes I writing for I2C and SPI:

Code:
#USE RS232(BAUD=9600,XMIT=PIN_C6,RCV=PIN_C7)
#USE I2C(slave, sda=PIN_C4, scl=PIN_C3, address=0xA0)
...
while(1)
{
   while(!i2c_poll());
   lcd_putc("\f I2C data: \n");
   value3=i2c_read();
   lcd_putc(value3);
}                //end while of I2C

while(1)
{
output_low(PIN_A5);
while(!spi_data_is_in() && input(PIN_A5));
if (spi_data_is_in())
value3=spi_read();
lcd_putc(value3);
}                 //end while of SPI




But it seems not work well. My LCD module would be treated as a slave mode, just being used to receive data from other hardware.

Thanks for your help indeed.
