  1. Hi,
    I am having TDA7418 Audio Processor connected with PIC18F(scl and sda) .  I am very new to this. Can anyone help me to tell how to configure and test TDA7418. ?
    anyone have source code for TDA7418.? Please share more details about it

    thank you

  2. unsigned short PortP0  ;
    unsigned short PortP1 ;
    
    void main(){
    {
       I2C1_Init(100000);      //100 KHz      // join i2c bus
    }
    while(1)
    {
    
            I2C_Start();
            I2c_Write(0x43);  //Read Address
    
          PortP0 = I2C_Read(0);
          PortP1 = I2C_Read(0);
          I2C_Stop();
    
           if(PortP0 == 0b11100001) //Making Bit 0 high
           {
        I2C_Write(0x42);//Setting the Slave Address for PCF8575. Write Address
        I2C_Write(0b11100000);// first 8bits
        I2C_Write(0b11111110);// Turn on led on Bit0
           }
           
    }
      
       }
    Hi all,
    I am trying to control switches in PCF8575 through I2C, when I press the switch which is connected in port0 in PCF8575, I want to glow the leds which i connect in port1 of pcf8575. i attached code. I cant able to read the switch status. Please help me to solve this. Switches are connected in po,p1,p2,p3,p4 with pull down resistors and leds are connected in p12,p13,p14,p15 with pull up resistors in pcf8575
