I/O labeling needs to be swapped?

Many Thanks for this very useful gadget. I use it successful with a button and your DriveSwitcher.

Since I use the PullUp R1 with my button, I had to use I2 as input and O2 as output.

I double checked the PCB and the LS74 Pinout an saw:

• Input I2 is connected to R1 and D1 (2) of the LS74
• Output O2 is connected to 1Q (5) of the LS74
• Input I1 is connected to R2 and D2 (12) of the LS74
• Output O2 is connected to 2Q (9) of the LS74

Is it possible that the labling of the I/O Pins need to be swapped? I1<=>I2 and O1<=>O2

You are right, the labels are incorrect. What is labeled I1/O1 is actually IN2/OUT2 on the schematics (and vice-versa).

I'm sorry for that but I am not going to make a new release just to fix that at the moment. Let's leave this open as a reminder.

I think it's safe to install the pull-ups in all cases anyway, there's really no need to wonder whether to do it or not.

Many Thanks for your confirmation and your great projects.

All the best!
