Download as PPT, PDF0 likes805 views
The document discusses development options for hardware/software solutions using Android and Arduino. It provides an introduction to Arduino, describing its open-source development environment and hardware capabilities. It then discusses connecting Arduino to Android using various protocols and development kits, including challenges with high Android API levels and emulator limitations. Alternative options like IOIO and Microbridge are presented.
Development, debug and deploy hardware/software solutions based on Android and Arduino
- 1. Development, debug and deploy hardware/software solutions based on Android and Arduino Ilya Rodin Senior Android Engineer Lohika Systems
- 2. Arduino
- 3. Introduction into Arduino Arduino is… Open-source electronics prototyping platform Open-source development environment A lot of electronics circuit elements, Arduino-base schemes and kits e.t.c 3
- 4. Hardware Microcontroller ATmega2560 Operating Voltage 5V Input Voltage 7-12V (recommended) Input Voltage (limits) 6-20V 54 (of which 15 provide Digital I/O Pins PWM output) Analog Input Pins 16 DC Current per I/O 40 mA Pin DC Current for 3.3V 50 mA Pin 256 KB of which 8 KB used Flash Memory by bootloader SRAM 8 KB EEPROM 4 KB Clock Speed 16 MHz 4
- 5. Development environment Cross-platform Java-base IDE Simple C++ base language •Begin • Well known language constructions (class, variables, loops, operators, methods, etc…) • You can use already created library setup() (LiquidCrystal, EEPROM, Servo, TinyGPS, erc…) • You can create new library, if it needed… Simple application life circle loop() Port Monitor toolkit etc… 5
- 6. … and something more Connection by Digital I/O • PWD • UART • I2C/TWI • SPI devices • DC motors • etc.. Connection by Analog port • Microphone • Sensors • AC drive • etc… 6
- 7. Hey, bro! What about Android?
- 8. Android Open Accessory Support in…and higher Android SDK 3.1 (API 12) Google API add-on lib for Android 2.3.4 (API 10) Implemented… USB Host Mode Accessory Mode 8
- 9. How it is work? 1. Wait for and detect connected devices 2. Determine the device's accessory mode support • The attached device supports Android accessory mode and is already in accessory mode. • The attached device supports Android accessory mode, but it is not in accessory mode. • The attached device does not support Android accessory mode. 3. Attempt to start the device in accessory mode if needed 4. Establish communication with the device if it supports the Android accessory protocol 9
- 10. AOA 2.0 New products Ids… AOA 1.0 • 0x2D00 – accessory • 0x2D01 – accessory+ADB AOA 2.0 • 0x2D02 – audio New features… • 0x2D03 – audio+ADB Audio output by USB (only for • 0x2D02 – accessory+audio Android 4.1 (API 16) and higher) • 0x2D03 – accessory+audio+ADB Support multi-connection with HID devices 10
- 11. Trouble… Limitations… High API level Some Android devices do not support Accessory/Host Mode Android Emulator do not support USB Resolving… Try use MicroBridge Mode Try use MicroBridge Mode ×Actually not resolved 11
- 12. ok, it is clear… ADK ?! O_o
- 13. Android Development Kit ADK 2011 ADK 2012 13
- 14. IOIO Spark Fun IOIO it is… Low cost PIC24FJ256-DA206 base platform Support connection by Digital Input/Output, PWM, Analog Input, I2C, SPI, and UART. Support Android 1.5 and higer 14
