Thanks cattledog,
I am testing with different pins but I think that there is not the problem, since I have done the following:
I have configured the SoftwareSerial like this: SoftwareSerial mySerial (11, 12); // RX, TX
I have tried the program and it does not work,
I have made a small program where there are no Timmer 1 settings that outputs the PWM signals from pins 9 and 10 at 12bits and a maximum of 4096 resolution steps. So this little program works fine. I understand that the configuration of pins 11 for RX and 12 for TX would be fine.
So I still think there is some interference between the timmer 1 prescaling and the SoftwareSerial.
Also add that I am using the RTC <DS3231_Simple.h> which is connected by I2C.
Any ideas?
