Linux-2.6.XXXX/Documentation/i2c is what i read. the problem is that #include <linux/i2c-dev.h> causes compiler errors because of the missing I2C_SMBUS_... macros in 2.6.x (if you want i include the error output, my example program or the linux/i2c-dev.h file i am using) although all this is fixable, i am surprised that i couldn't find any howto/tutorial/advice on that - or am i the only one having this problem ? thanks, nils
