  • AD1941 I2C Reading Problems


    I have developed the micom control program using AD1941 Sigma DSP.

    I developed a custumized AD1941 board and it is working very well.

    But, the only one problem is the I2C data read. (There is no problem when I2C data writing.)

    I tried to read…

  • AD1941 clock frequency at I²S output (serial data I/O ports)


    I would like to use the Sigma DSP AD1941 to equalize music. But I have to know which clock frequency has got the I²S port (serial data I/O port) because I want to transmit the music via FM-Transmitter to a car-radio. The FM-Transmitter input must…

  • RE: Hi, how can I get a sigma studio soft  key?

    Different subsets of algorithms run on different SigmaDSP processors. Some algorithms are not available on all processors due to memory limitations.

    The reverb algorithm is available on the AD1940, AD1941, ADAU1442, ADAU1445, and ADAU1446 SigmaDSPs.
