Re: Si5351 audio pops and PLL Lockups

Thanks Ron!

This is my first Arduino project, and though I was wondering why so many Arduino based radios used IO lines instead of the I2C Bus(it seemed to me they were going through a lot of effort), now I know why!

I haven't gotten to hacking libraries yet.
However, after making the HW changes that Dave suggested (which involved removing the pullups from the encoder/moving them to code), and changing 2 parameters in the code, all seems well. I've been tuning all over the dial with no pops, clicks, or PLL drop outs.

The 2 lines of code I changed were:

attachInterrupt(digitalPinToInterrupt(PinA), Dial, FALLING) ... instead of LOW

and
if (interruptTime - lastInterruptTime > 10) { ... instead of 5

Changing from calling DIAL on a LOW to calling DIAL on a FALLING edge made the largest change.
Increasing interupt debouce was just added insurance ;)

Sounds like great stuff to me....  I would have been talking to you about your "miracle antenna".....  I was thinking that would make a good "Mini" podcast to help replace our loss of Ozarkcon..Maybe Tinker John could do another one and or any of the other presenters as well..   Just some thoughts from an old ham.

Re: Si5351 audio pops and PLL Lockups

Ron Carr
 

There is another buffer of length 32 defined in directory utility in file twi.h
Without wading through all the code, I would guess you would need to increase this one also.

Re: Si5351 audio pops and PLL Lockups

Ron Carr
 

You have the Si5351 and your LCD both on the I2C bus.  That is a lot of I2C activity.  ( Personally I think the Wire library is brain dead as it uses interrupts but still blocks until all the activity is done. )

The Wire library has a buffer size of 32.  If the buffer is full, the code just drops the data and sets an error.  So you may be dropping some writes to the Si5351 when things get busy.

Here is the code from the wire library where it drops data...

size_t TwoWire::write(uint8_t data)
{
  if(transmitting){
  // in master transmitter mode
    // don't bother if buffer is full
    if(txBufferLength >= BUFFER_LENGTH){
      setWriteError();
      return 0;
    }

To see if this is the issue you could edit the library to increase the buffer size.  The file to change is Wire.h.

On my computer ( I installed to directory Arduino ) the path is:   C:\Arduino\hardware\arduino\avr\Libraries\Wire\src
If you have other versions of Wire in your own libraries, then you will need to find the one the compiler uses.

Winlink *can* depend on the internet, but it also includes a peer to peer mode that does not require gateways or internet access.  In that mode, it's pretty similar to a traffic net - operators bounce the mail around, and then take care of the "last mile".
