Question: 1. A pin gets pulled low even though the simulation shows it correct? 2. I get daisy chain errors, why?
Answer: Please check the power supply voltages. There are instances where a 5V power supply has been used on a 3.3V (V) part, and this resulted in functionality issues on a few pins. This difference in power supplies can also result in failed daisy chain errors when programming.
