hey forum

Has anybody some experience with the Philips TDA 8444 6 bit octal DAC, that they want to share? I am trying to use this DAC, but cant reach it. I think my i2c rutines are okay; i can read and write a PCF8574 port expander with out problems, but using the following steps - from the data sheet - nothing happens.

void write_DAC (unsigned char i2c_data)
{
i2c_start(); // Send I2C Start Transfer
i2c_write(0x4E); // Send identifier I2C address - Write
i2c_write(0xF0); // Send control byte to device
i2c_write(i2c_data); // Send data to port
i2c_stop(); // Send I2C Stop Transfer
}

Any comments much apreaciated
