Pull-up/down resistors or sort circuit ?

Post by kmiha » Thu 2018-04-05 16:18

Hi,
Can I connect the unused VS1003 inputs for instance GPIOs/xDCS/xTEST/RX pins directly to power supply/gnd pins or it is a must to connect them via resistors ?

inputs can be connected directly. I/O:s need resistor. Check datasheet for each pin type.
