Si4704 FM Arduino Debug Steps   by Patrick

 

1. Program the sample code to Arduino.

2. Connect the Si4704 module to Arduino.

3.3V : VCC

   GND : GND

   A5 : SCLK

   A4 : SDIO

   D2 : RST

   A0 : Trimpot (optional)

Note: left column means Arduino pins, right column is the Si4704 pins.

3.  Use a serial terminal console, baud rate is 57600, wait for several seconds:

It will display:
