You can select from a number of options when looking for a suitable Wii ROM source. Its extensive range of Wii games is always ready to attract a potential gaming crowd. WiiNunchuckReader.Nintendo is an undefeated leader in the gaming world, enjoying the priorities of gamers globally. WiiNunchuckReader.h - WiiNunchuckReader class declaration WiiNunchuckDefs.h - Nunchuck related defines I2CConfig.h - defines I2C ports and pins. A useful table of nunchuck max/min values can be found at, which also has a sample Ardunio program.:Library Files. I use a 10ms delay.Ī good explanation of I2C can be found at. Luckily the mbed I2C library doesn't support a single operation 'write address/read data', and this has to been done as a seperate read and write, allowing the delay to be inserted between them. The Wii Nunchuck is unable to do this and requires a delay between writing the device 'read' address and the data read. A well behaved I2C device should be able to do this in one operation (with the two sequences seperated by an ACK). Nunchuck I2C:Īn I2C read operation consists of writing the device read address followed by requesting the data. All values are returned as un-normalized integers.įor debug you can read the WiiNunchuckReader internal buffer and get the raw nunchuck data (getBufferSize( ), getReadBuf( ) as in the example above). It then reads back the nunchuck values back and decodes them. This sends an initialisation sequence to the nunchuck the first time its called. Nunchuck values are then polled or read as required from each WiiNunchuckReader. This connects a nunchuck to an I2C port (A or B) with the required pin outs and clock frequency. WiiNunchuckReader nchkB(I2CPort_B::SDA, I2CPort_B::SCL, I2CPort_B::FREQ) įirst step is to create one or two WiiNunchuckReader using the definitions from I2CConfig.h. WiiNunchuckReader nchkA(I2CPort_A::SDA, I2CPort_A::SCL, I2CPort_A::FREQ) Serial.printf('%d ', nchk->getJoyY()) Serial.printf('%d ', nchk->getAccelZ()) Serial.printf('%d ', nchk->getAccelY()) Serial.printf('%d ', nchk->getAccelX()) Serial.printf('%d ', nchk->getButtonC()) Void ReadAndReport(WiiNunchuckReader* const nchk, const char* const portname)

The demo also illustrates how to use the library. The demo displays (on a terminal emulator such as Tera Term) the Z and C buttons, the X, Y, and Z accelerometer values, and the X and Y position values polled every second.

Finally mbed p9 to Data and p10 to Clk on adapter 1, and mbed p28 to Data, and p27 to Clk on adapter 2.įor the code to work you don't need both nunchucks connected, either one will do. So for both adapters you need to route the mbed GND pin to Gnd on both adapters, and the mbed VOUT (3.3V regulated out) to 3.3V on both adapters. Now updated to use the I2C read/write error return values, so you can now leave one nunchuck unconnected without any issues.įinally: you don't need any pull resistors, as the Wii Nunchuck has internal ones on the I2C lines.:How To Use. I got my adapters from Active Robots in the UK () In order not to put a strain on my laptops USB (100ma limit), the mbed is powered (Vin) by a 5V PSU. The mbed supports two I2C ports, and as the nunchucks have the same I2C address, one goes on each port.įor my set-up I use the Solarbotics Nunchucky breakout adapters, and powered the 3.3V for the nunchucks from the 3.3V output of the mbed board. Main.cpp is the demo program and is written for two nunchucks.

This version is a port from my own Arduino version, which in turn arose from trying to figure out the Wii Nunchuck I2C using the PIC Serial Analyser and writing some test scripts (which is a story in itself).
