Version one has not got a 10k pull up resistor on the cs sd card line.
Version two does have this.
Teensy 3.6 does not have the resistor either.
Is this 10k pull up required on the sd card cs line? If so why? Its just a gpio line and the software has full control over its output state.
I am adding a sd card to my custom board (to be used with the teensy audio lib) and just wondering if i need to add this resistor or not
One note the sd card will be the only SPI device on my board. Do i even need the cs line? Can i just ground it?
