Use any unused port number eg:4568Ĭonnection = ADB::addConnection("tcp:4568", true, adbEventHandler) įinally, install the Android Demo application onto the device. Open an ADB stream to the phone's shell. PinMode(i+2,OUTPUT) // Set pins as output LEDState = data // Store the State of LED

#ARDUINO USB HOST SHIELD CODE SERIAL#

Serial.println(data,DEC) // Output debugging to serial In this example Data packets contain three bytes: one for the state of each LEDĭigitalWrite(i+2, data) // Change the state of LED Void adbEventHandler(Connection * connection, adb_eventType event, uint16_t length, uint8_t * data) Event handler for shell connection called whenever data sent from Android to Microcontroller You can checkout the source for the Arduino sketch from Github, or just copy and paste the following into the Arduino IDE. Microbridge uses Android Debug Bridge (ABD) forwarding over TCP, rather than the official Google Android ADK. The sketch uses the Microbridgeimplementation by Niels Brouwers. Next, upload the Arduino sketch to the microcontroller. Here is a diagram of the completed circuit (created with Fritzing): The resistors, in this case, are being used to prevent current overdraw to the LEDs. The example uses digital pins 2, 3, and 4, but can be used with any IO pin that doesn’t interfere with the SPI communication with the USB Host Board.

Google ADK board, Freeduino ADK board , Seeed Studio ADK board, and DIY Drones ADK boardĬonnect the 330 ohm resistors in series with the anodes of the LEDs to the desired digital output pins, and the cathodes of the LEDs to ground. For additional background information on Android development, Arduino, and MicroBridge, check out these links:įirst, make sure you have setup the development environments for Arduino and Android: The goal is to demonstrate the easiest possible use of the technology. This article will discuss the bare minimal requirements for development of an Android USB digital output device.

So if the code in the initialization use HAL library(GPIO or SPI),to control IO pins, for example, it is not initialized yet.Simplest possible digital output with Android and Arduino.

The c++ global object initialization is done before the _main is executed. Global class initialization to control IO pin In Keil, need to specify #pragma anon_unions before the anonymous union definition in usb.hpp. This is important especially in definition of USB packet. unsigned int should be changed to uint16_t in STM32. Variable size in Arduino is different from STM32.

reconnect the MAX3421E_RESET to Arduino pin D7, CPU(PA8).

Remove all 1000 ohm resistors for SPI signal.

Sparkfun version use IO pin to control it. MAX3421E reset signal connect to Arduino RESET pin. It uses two resistors(4 ohm)for each SPI signal to divide voltage.Īlso it could be unstable with 3.3V CPU like STM32. This hardware version has 2 features that is not the same as sparkfun's.ĭoesn't have hex converter to convert 5V to 3.3V level. Power Pins Power Pinsĭownload orginal Android ADK library from ( ) Hardware Changes of USB Host Shield If not,ĭisconnect the SB21 at the back of board. Since SPI1_SCK is output, it should be OK just leave the LED connected. Using STM32 CubeMX configure the Arduino pinout for USB Host Shield. We will provide 7-12V from the VIN pin of Arduino Connector(CN6 pin 8) Interface pins

We need to configure the Nucleo board using external power. USB host shield need to provide power to device. Porting Arduino USB host shield to STM32 using STM32F070 Nucleo. The demokit of orignal ADK use Arduino ADK or Arduino with USB Host Shield.

This project is used to connect Android device with STM32 using Android ADK(2011).
