Scale connected to one half of 339. Clock and data connected to P2.1 and P2.4. Powered up, connected. Scale and display zeroed. Scale moved, display Y axis and scale value match.

Powered down, P2.1 linked to P2.0 P2.4 linked to P2.5, powered up ,connected.

Y axis display now continually jumping about. If the scale is moved X axis value changes and a number shows without changing most of the time but then for a fraction will show a completely different number..

Powered down.

Just for fun P2.1 linked to P2.5 and P2.4 linked to P2.0. Powered up connected.

X axis jumps about erratically however Y axis now stable and correct and following the scale.

Is the controller trying to supply the clock? I believe you need to do that on some types of scales.

Let me know if you need more tests
