This is not a real package.

It give i2cdetect programm - a user-space program to scan for I2C devices
and ds75ioctl - client programm to drive DS75 i2c thermal sensor.

Use :

make menuconfig

and choose :

Utilities -> <M> i2cdetect

You will get i2cdetect_0.1-1_mips.ipk.

i2cdetect and ds75ioctl can be used to check i2c support on La Fonera :

ipkg install i2cdetect_0.1-1_mips.ipk

root@OpenWrt:/# i2cdetect -l
i2c-0   i2c    GPIO adapter  Algorithm unavailable

root@OpenWrt:/# i2cdetect 0 
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-0.
I will probe address range 0x03-0x77.

48 ? Hey ! We got a i2c device here ! Let's use ds75ioctl :

root@OpenWrt:/# ds75ioctl -d /dev/i2c-0 -a 0x48
