None of the chips on the Uno are designed to be a host. It has a chip that is designed specially to be a USB host so you can plug a device in to it. To do it with anything less powerful than a Due you require additional hardware that is specifically designed to be a USB host - and that is where the USB host shield comes in. The Arduino Due uses a far more powerful chip, and that is capable of being a host (using what is known as On-The-Go mode). If you want to plug a device into something it has to be a host (note: I am purposely ignoring hubs here). The small USB interface chips they use are very low powered and can only be a device, never a host. Being a device means just communicating with the host in your own way.Īs you can see it is a far more complex job being a host than being a device.Īrduinos are devices. You have one Host (usually your computer) and many Devices (such as Arduinos, Printers, Scanners, Webcams, WiFi dongles, etc).īeing a host involves knowing about what devices you are going to have attached to you and how to communicate with them. In USB there are two main 'things': Hosts and Devices. The commands can be found in the file things first you need to learn the basics of how USB works.

I also like to get the Ethernet kit (4 USD) just in case I want to use the hardware 10/100Mbit wired Ethernet connection also. Now you can control the Board via Rx/Tx (UART). Id suggest a Teensy 4.1 (about 27 USD), plus the USB Host connector (about 3 USD, only need to solder standard 4-pin 0.1' spacing pin header). Remove the short-circuit between CS1 and GND. Remove the USB connection from the Board. Select VS1000D -> Upload USB boot file and choose VS1000_B.RUNĬopy the file boot.img to the new drive with the Windows Explorer. Make the following settings and press USB Search: Nominal Size: 256 MByte Set CS1 to low: add a wire from GND to R5 (100k).Ĭonnect the Board to the PC via USB and press the Power button on the Board.Ĭheck the new drive. Remove all connections from the Breakout Board.

Software: Flash-Tool, VS1000 UART-Control Firmware Yellow/ White wire of servo to digital pin 2 NOTE: The pins on the shield are the same as the Arduino pins that are directly below. For more information about this library please visit us at. Warning: Make sure to not force the pins down, gently wiggle USB host shield until pins are completely covered NOTE: make sure it’s a Microsoft adapter. The SparkFun USB-Host-Shield has additional connected Reset and GPX from the MAX3421E to the Arduino pins 7 and 8.įor a correct function of the USB Host Shield 2.0 Library from you have to initialize these pins in setup() before using the library. The USBHost library allows an Arduino Due board to appear as a USB host, enabling it to communicate with peripherals like USB mice and keyboards.
