    Communication between PIc and an external EEPROM

    Hello, glad to tell that it work, my mistake was in addressing the second time (line 22 from the start) I should write the address of the eeprom in the right form. I changed the I2C1_Wr(0xA1); with I2C1_Wr(0xA0);

    Communication between PIc and an external EEPROM

    Hello, I need to save some data in a 24LC256 eeprom from a pic, the eeprom work with I2C. I linked the sda and the scl pin with 2 pull up resistor of 4.7kohm, linked the 3 pins A0 A1 and A2 with the ground. The eeprom then has the address of 0XA0 for read and 0XA1 for write. This is the PIC...

    Extracting audio information from HDMI

    Hi, thanks for your replay we find this circuit the "TDA19977A" which can decode the HDCB and can send all the audio infoframe through a pic microcontroller via please take a look and tell me what do you think of this device. This is too good to be true! **broken link removed**
