Problem with LEONARDO and SevoTimer2 library

Projects Programming
1

I am not able to compile any sketches referencing ServerTimer2 library when LEONARDO board is selected.

Here is a sample code.

#include <ServoTimer2.h>
ServoTimer2 a;
void setup()
{
   a.attach(5);
}
void loop()
{
  a.write(1500);
}

And the error message is:

Any suggestions how to deal with this?

Thanks,

Looks like something is wrong with that library.

Try the standard Servo library and use .writeMicroseconds()

Thanks for the reply. Unfortunately I can't easily switch to another library since I am not referencing it directly. It is used by other libraries that manage I2C and sensor data. Note that this problem only exists when compiling sketches for Leonardo. With other boards everything works fine. Any other suggestions?

Ask the author of the library to update it to work on Leonardo or switch to an UNO.
