Hello, I installed the EC11 rotary encoder (20 steps 20 pulses according to distributor) in two units of the LCR-T4 those yellow color (Chinese clones) and with the firmware m everything works perfect, right, left, slow spin, normal spin, Quick spin etc.
But with the k firmware, it works fine but only with slow turns, if you turn the encoder at half speed or fast the screen fails, text lines jump, vertical streaks go out or it goes blank even though the tester keeps running.
Example:
I have compiled the latest version available (Trunk 699) with the options:
CFLAGS += -DWITH_ROTARY_SWITCH=2
CFLAGS += -DCHANGE_ROTARY_DIRECTION
I have also put the Pull-UP resistances recommended in the manual and quartz crystal at 16MHZ (photos in post # 3006 a little higher).
It happens to me in the two units exactly the same, is that normal?
