I think there might be the pins settings that are pointing to somewhere else, or I'm just using the wrong libraries for my board. Digital pin 4, 7, 8 and 12 are used to drive the DC/Stepper motors via the 74HC595 serial-to-parallel latch I was just wondering if there is a way to switch these occupied pins to other pins because I am also using a USB host shield with this project and the USB shield uses pins 8-13. ), but nothing happened.Īlso, I tried using the Greiman's library ( ) with the DriveInfo example ( ) and it only returned: UsbFat version: 20141220 I have tried using Kroll's library ( ) to do some mass storage testing and see what happens (i.e. The main goal is: I want to read a text file from a flash drive plugged into its USB port.įrom the board's documentation, I know that the USB Host module uses the following Arduino pins: 7 - RST It has a built-in MAX3421E USB Host module. I'm using an Arduino Mega 2560 (Iteaduino ADK v1.0d to be more specific, like the one shown below).
