Target cable with twisted pairs
Step 1: Use separate unshielded wires to minimize capacitance and reduce crosstalk. Step 2: If the problem persists, add a capacitor of approximately 22 pF (acceptable range 18–27 pF) between CLOCK and GND on the nails, as close as possible to the MCU. Step 3: If the issue still exists, add a similar capacitor (≈22 […]
