Hi,
I have soldered 10K resistor on the DATA for CD4021, but the problem persists frown

Let me make a summary:
- B-5 grip with CD4021 is working fine with Warthog base,
- both TLE5010 are working fine,
- I use separate CS for each chip,
- I use separate DATA for CD4021 and TLE5010s,
- I have 10K resistor on the DATA for CD4021,
- I have checked all cables from end to end and I haven't found any short circuits and believe there are no errors in design.

#%&*$#! What else can be wrong?

@Sokol1,
your schema looks like the maze wink
