Hi!, I have a setup with a PIC24FV16KM202 and a Si4703 in I2C mode. 

If I touch any of the pin's at the Si4703 breakout board the music stop's and the frequency is changed to 87,5MHz??

In my search I have soldered 1uF at the +3.3v and gnd, and I still have the issue.


Thank you for your time.

  • Hi Elmek,


    The host MCU may be reset when you touch the wire. 
    Can you check the voltage of the power supply when you touch the wire?

  • Hello,


    Please have a try of the circuit in attached file. The RC circuit(resistor and cap) need to be placed very close to the pin5 of the tuner.
