When Windows 7 came out and I learnt about the new Sensor and Location Platform, I figured writing up a little bridge driver that exposed the 3-axis accelerometer that each Wiimote comes with to the sensor platform would be kind of cool. This article attempts to explain how the driver works and what it takes, in general, to write a driver for the Sensor platform. Use a Wii Remote to Control a Computer: I wanted to make something like this using Python, but I kept failing, mainly because this computer runs windows. I really hate writing poor reviews. I bought this adapter last year with the whole intention of buying a Wii U and SSB and using it with my Wavebird controller. Needless to say I had never gotten Smash Brothers on the Wii U and I kept this adapter in the box in my closet unopened or used. Regarding the Wii Remote input: Current development focused on the kernel driver. The next steps will be writing mouse/keyboard emulations based on the driver. It will take some time, though. However, if your X-Server supports input-hotplugging you should be able to at least use the D-Pad as UP/DOWN/LEFT/RIGHT keys.

To simplify the process of creating V-USB based devices, I created the USnooBie.

USnooBie official site

You can buy it from Seeed Studio, it should come with all the parts you need and the bootloader all ready to go.

The USnooBie is a microcontroller kit that does not require any sort of AVR programmer or USB-to-serial converters to load and run compiled code. It's hardware design allows the user to develop low cost USB devices with Atmel's AVR ATmega microcontrollers. It can also be used to develop projects which are not USB devices. It is even compatible with Arduino.

USnooBie Assembly Instructions and Parts Breakdown

This is a short version of the official assembly guide, visit the official assembly guide to read more details.

Assemble the USnooBie according to these steps. The smaller components must be soldered first, before the larger components, this makes assembly easier. The parts required are also described here so this document also acts as a part list so you may find replacement components.

Two 68 ohm resistors

These resistors limit the current between the USB device (microcontroller) and the USB host (computer) on the D+ and D- lines of the USB bus. They act as terminating resistors, so the terminating impedance matches the USB cable's characteristic impedance, reducing signal reflections. They are small and low components and are thus soldered first.

These should be two 68 ohm 1/4 watt +/- 5% tolerance carbon film resistors.

D- pull-up resistor

This resistor is placed on the D- line of the USB bus. When D- is pulled up, it indicates to the USB host that the USB device is a low speed USB 1.1 device. This resistor is usually 2.2 kilo-ohm if pulling up to 5V and 1.5 kilo-ohm when pulling up to 3.3V. 1.8 kilo-ohm works well with both 5V and 3.3V.

This resistor should be one 1.8 kilo ohm 1/4 watt +/- 5% tolerance carbon film resistor.

Note: the original design used a 1.7 kilo ohm resistor, the kit being sold is provided with a 1.8 kilo ohm resistor, either should work. The schematics may show a 1.7 kilo ohm resistor (typo, sorry).

LED current limit resistor

This resistor limits the current for the power indication LED. If this current is not limited, then the LED's lifespan is drastically reduced.

This resistor should be a 330 ohm 1/4 watt +/- 5% tolerance carbon film resistor.

Two 3.6V Zener diodes

These 3.6V Zener diodes ensures that the signal on the D+ and D- lines of the USB bus are within acceptable limits. This allows the USB device to run at 5V without damaging other devices on the USB bus.

Download game gta 5 versi java. These should be 1N5227B 3.6V Zener diodes. There have been reports that certain Zener diodes will not work. 200mW Zener diodes may not work but 500mW Zener diodes will (source: http://forums.obdev.at/viewtopic.php?f=8&t=4677).

Ensure that you place these parts in the correct orientation as indicated by the symbol on the PCB. The triangle on the symbol points in the direction which the stripe on the diode should be.

Reverse current protection diode

This part is not included in the kit provided by Seeed Studio. You must replace this part with a jumper wire or else the USnooBie will not receive power from the USB port.

Power indicator LED

This LED indicates that there is power on the power bus. Note that it does not indicate the amount of power, so even if it is lit, it does not guarantee that certain components are receiving enough voltage.

This must be a 3mm diameter standard LED.

This LED may be omitted if you want to save power or you want a 'stealthy' USB device.

Ensure that you place this part in the correct orientation as indicated by the symbol on the PCB. If you are unable to determine the direction of the LED, then you should test the LED before installing it. The 'flat side' should be the cathode, which should be negative to light up, while the 'round side' is the anode, which should be positive to light up. Use a 3V coin cell battery to perform this test really quickly to avoid damaging the LED.

USB A male connector

This allows the USnooBie to be plugged directly into a USB port, or you can buy a USB extension cable from the dollar store to connect it.

Two tactile SPST momentary on push button switch

One button is used to reset the AVR microcontroller, the other button acts as a bootloader activation button. Upon reset, the AVR runs the bootloader section code which checks whether or not the bootloader activation button is held down. If it is held down, the bootloader becomes a USBasp device so you may load your own code into the AVR microcontroller. If it is not held down, then the bootloader jumps to the application section to run the code you have previously loaded.

This bootloader activation button is placed on the D- line, when pressed during normal use (not during boot time), it will cause the USB device to appear disconnected from the USB host. This is useful in certain situations when you require your device to disconnect without physically disconnecting.

The Omron B3F-1000 tactile SPST momentarty on push button switch should be used here.

28 pin DIP chip socket

A 28 pin DIP chip socket is used to hold the AVR ATmega microcontroller.

Due to the placement of the three tandum capacitors, a 28 pin DIP chip socket must be used (or two 14 pin DIP chip sockets, the PCB layout is designed to allow this) to hold the AVR ATmega microcontroller. The chip socket should have a gap down its center, giving you room to place the three capacitors. Solder in the sockets first, then insert the capacitors through the gap. See the picture provided.

Ensure that you place this part in the correct orientation as indicated by the symbol on the PCB.

Do not insert the chip into the socket until the board passes some simple testing (later steps).

Three monolithic capacitors

The 0.1uF capacitor is a decoupling capacitor which smooths out fine ripples on the power bus. The code on this capacitor should be 104 (meaning 0.1uF).

The two 27pF capacitors cleans the signals from the 12 MHz crystal. The code on these capacitor should be 270 (meaning 27 pF).

These capacitors can be monolithic or ceramic.

12 MHz crystal

The 12 MHz crystal is the clock source for the AVR microcontroller. It is 12 MHz because that's the best clock speed for 3.3V opertation that is supported by V-USB.

The crystal must be a 12 MHz crystal in a HC49 package. Low profile packaging is prefered, as long as the pin spacing is the same.

Voltage selection jumper

A three pin header is used to select the voltage on the power bus, a shunt block is used on the 3 pin header to make the connection that makes the selection. This allows you to choose between using the 5V power supply from
