SI4713 FM Transmitter

Post by w0ivj »

I am using the Adafruit si4713 library with the provided example on a Nano Every. The transmitter only works if the serial monitor window is open on the Arduino 1.8.13 IDE.

Check your code to see if it has something like this at the top of setup():

Code: Select all

   while ( ! Serial ) { delay( 1 ); }
That's fairly common for microcontrollers that handle USB internally, but hangs when there's no USB connection.

Thanks...I solved the problem with an external reset button that I use after the power is applied.
