The second version of my driver for the I2C unit in Motorola's MPC107 bridge chip, plus the 824x integrated processors, is now available: http://www.humboldt.co.uk/mpc10xi2c.html The changes in this release are: *) Now interrupt driven. *) Faster startup. *) Fixed bug in the stop condition (thanks to Timo Rossi). *) Uses official adapter and algorithm numbers. Once more, I welcome feedback on how it works for other people. - Adrian Cox http://www.humboldt.co.uk/
