Using the USB host shield with MAX3241, arduino is the host and android is the device.
In USB_Host_Shield_2.0 library
USB_Host_Shield_2.0 > examples > adk > “term_time”, we believe we can send data from arduino to android.
Question 1, In the test, the arduino is powered by the PC.
In addition, 5V is output from port C of the USB host shield to supply power to android.
How to connect the USB host shield to the android, should I put a USB OTG cable or something in between?
I understand that I need to create an android demo app with Android Open Accessory.
Question 2, I had a hard time making a demo app on android, so I changed the purpose once.
First, I wanted to check the output from the USB host shield, so I would like to download an existing terminal emulator application for android and check the serial output from arduino, with android as the host and arduino side as the device.
The way I connected the android to the USB host shield at that time, I connected it across USB OTG.
Then the LED on the USB host shield is blinking.
What is the status of this?
The state of the MAINPOWER switch at this time is OFF, and no output should be taking place from port C of the USB host shield.
Thank you in advance for your response.
