Userspace vs kernel module

Initial research in Linux I2C implementation (yes, believe it or not, I dived into this head-first without any prior knowledge of how linux i2c worked) revealed that besides direct kernel-space adressing, I2C devices can also be adressed from userspace via the device file system by means of the i2c-dev module. Since it will apparently be quite easy to actually bake together the contraption once I uncover a source of parts (which I haven't really looked into much so far), be ready to access the module from userspace for the time being, because actually writing a dedicated kernel module for the chip will definitely be the trickier part of the project. --Drdeath 00:14, 26 July 2009 (UTC)
