For the CW operators here ... have you had any problems with the sBitx CW keyer?
The timing seems off for me when keying at higher speeds, and the TX isn't quite right even using an external keyer. I took a couple of videos showing what I mean:?
Using an external keyer at 25 wpm, the dits are much more staccato than they should be and sometimes entirely cut off. The TX is bad enough that the RBN will not pick up my call when using the external keyer:

Using the sBitx internal keyer at 25 wpm, there are many keying mistakes introduced by the software, for example when keying the word "POTA", which is a word many of us will be keying of course:?

Keying using a small keyboard or a save message seems to work fine, so that's good :)?
I noticed the code polls the GPIO associated with the key only about 10-20 times per second, which I think is much too slow for faster keying, so I was thinking about rewriting it to use GPIO interrupts to change the CW flags instead of repeatedly polling the GPIO.
Does anyone have thoughts on this as a possible approach??
Thanks,?
