Re: Updated documentation?

[Ytai Ben-Tsvi]

IOIOLibCore translates the main IOIO API (ioio.lib.api.*) into a
bidirectional serial protocol that the IOIO understands.
IOIOLibAndroid adds an implementation of the serial channel over TCP/ADB as
well as ties the IOIO application model (IOIOLooper, etc) into the Android
application framework. Then, other IOIOLibAndroidXXX merely add more
connectivity options.
Similarly, IOIOLibPc adds support for serial ports as the serial channel to
the IOIO as well as bindings to the Java console or Swing application
framework.
Hope this makes things clearer for you.

Re: Controlling LoRa radio with IOIO

[Ytai Ben-Tsvi]

I don't know specifically about this radio, but indeed SPI is possible.
Usually, unless the device has some weird timing requirements, there should
be no problem. You should be able to translate the Arduino-based library to
Java.
Alternatively, you can leave the Arduino in the loop and use the Android as
display only. In this case, what I would do is have the Arduino present the
data that needs to be displayed over UART or I2C and consume it via a IOIO.
Another option is not to use the IOIO and use one of the Arduino boards
that can talk to Android over USB or add a Bluetooth shield to the Arduino.
