![]() ![]() ![]() 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. Support for more devices is currently in development.This project is used to connect Android device with STM32 using Android ADK(2011).Digital cameras - Canon EOS, Powershot, Nikon DSLRs and P&S, as well as generic PTP.USB to serial converters - FTDI, PL-2303, ACM, as well as certain cell phones and GPS receivers.HID devices, such as keyboards, mice, joysticks, etc.The following device classes are currently supported by the shield: This shield is shipped as the picture has shown, containing a populated and tested board plus a set of stackable headers, which is properly soldered.Īrduino Compatible board with standard connector layout, including ICSP connector, should work. Note: You will need to solder some of the pads to provide power to the USB socket and also the shield. No more SPI re-wiring and code modifications! This is a great shield if you want to interface with Android phones or tablets too :) Thanks to the new interface layout it is now compatible with more Arduinos - not only UNO and Duemilanove but also big Mega and Mega 2560 work with Standard variant of this shield out of the box.
