Re: W8TEE vfo encoder fix

I don't understand this quote:

No matter how fast I turn the encoder, it will only change the LSD. 7.258.9 the encoder will only change digit after the 8.

Have you tried changing line 61:

#define DEFAULTINCREMENT????? 100UL??? // Make it a long since it works with frequency

Change that term to 1UL and see what happens.

I have had problems like that.? My 3D printer take forever to read the encoder?
The encoder library used to have a spot to declare that?? You could mess with the steps.
I moved the change code into the interrupt to read the frequency on one project.? The interrupt sets the frequency, not a change Flag.
Most just set a Flag and wait for the Loop Routine to see the Flag and set the Frequency.? May cause a delay?
Then it reads it as soon as it moves.? Maybe some de-bounce caps on the encoder.? Make sure pull ups enabled or use resistors on the encoder.
Mine has them.? I have tried .01 to .1 uF.? I have 10K pull-ups too.
You might look at that?
A problem I have had too!

Well gang,

it's not elegant, but solved the problem. You can't go too fast, as the software can't read the encoder at top drill speed.




Seriously, anyone come up with a fix to this? My encoder takes two clicks to make a digit change. Perhaps my Chinese encoders aren't aren't sending the necessary pulses to the ardunio.

the encoder will only change digit after the 8.

Still playing, still having fun
