the Arduino pin connected to the SS line) when using the USB Host shield library (or any of the pins used by the library), in setup(). However, it does not appear to be possible to simply specify the "select pin" (i.e. So, one could use a pin (or pins) that is not reserved by the Ethernet shield. However, I could employ one of the small form factor boards, such as the USB Host Shield 2.0 Arduino UNO MEGA ADK Compatible Google Android ADK which I found on eBay:Īs this board is not in the usual shield "shape", one would not be constrained by which pin to connected to which MAX3421E input/output, in particular the chip select (SS) input.
I would like to add USB host functionality, to a particular Arduino setup, whilst, also, being able to use an Ethernet/SD (or just SD) shield.Īs both the Ethernet shield and USB Host shield use pin 10 to select the W5500 and MAX3421E respectively 1, obviously I can not use a standard USB Host shield. Which is the correct file to modify the Arduino pin used for the USB Host slave select (SS) line?.
