Hi, the shield arrived yesterday. I followed the instructions and I have the same errors (post of Lars) while compiling. Is there any information about what we are doing wrong? Latest ArduinoSDR; Arduino IDE 1.6.9 Any help is welcome! Best regards, Johan

You are right and i have to excuse for NOT removing the line:  #include <Adafruit_Sensor.h>   In my case also without removing this line, compilation did work without any problems, but there was some place, where Burkhard Kainka ( program author of original firmware ) meanwhile did write about this ( text automatically translated by Google ): Elektor-Labs reported that there were problems with entry #include <Adafruit_Sensor.h> What actually has to do with the sensor library, I've also asked myself. After some search, it has become clear. This library was falsely registered in Adafruit_SI5351.h, but was never used. To compile everything I had to use it in my source code. Meanwhile the error was corrected in the current library. And anyone who now uses the new library with my cold source code will get an error message. You must then remove the line #include <Adafruit_Sensor.h> from the source code.

Hi Christian, This is the problem: the voltage across the zener diode is probably expected to be almost always 6.8V, except at the zero crossings, where it is supposed to be zero volts for a short time. If you look at the "Simulation over longer time" a few posts back, then you can see that, after a while, the voltage across the zener is always 6.8V, and has no longer zero crossing pulses. This is probably due to C1 building up a charge and never uncharge. The current state of the project (it is actually only a part of a project, it does not actually do anything on its own) is an extra emitter follower at the "cold" side of the optocoupler and a resistor of a much higher value at the "hot" side (with very low dissipation). I will publish the updated circuit diagram soon.

Hello, The sketch si5351vfo3.ino is compiled with a lot of errors when the line :#include <Adafruit_Sensor.h> Is present THe first error is:undefined reference to `Adafruit_SI5351::setupMultisynth(unsigned char, si5351PLL_t, unsigned long, unsigned long, unsigned long) Everything seems to be OK without this line. Can you tell me the purpose of tis line, there is no sensor in the SDR Thanks, Ikkeje
