latest bleeding edge firm now up
here. Tested it but if you find any bugs let me know.
For the 8 seconds standard delay , it is easier to achieve with this firmware, but still not that easy.
Go to mode 1.
Quantize to get 1:1 forward easily, set that with DIR 1.
Set LEN B fully CW. (up to heare is probably what you tried with old firm)
Push and hold Q up.
With Q held jiggle LEN B then leave set at fully CW.
Release Q switch.
Tap the soft switch (led should flash white briefly if tap is detected).
The delay is now ~8 seconds.
If you read the post linked above you may get why that is how you achieve 8 seconds.
The other features added are explained in the post.
Enjoy.
