From b411d7f2288ce688fe67db8c157a7721b70bc20d Mon Sep 17 00:00:00 2001 From: Andy Walls Date: Sat, 21 Jun 2008 21:27:00 -0400 Subject: cx18: Add I2C slave reset via GPIO upon initialization From: Andy Walls cx18: Add I2C slave reset via GPIO upon initialization. One user, Michael , has reported this allows his HVR-1600 EEPROM to be consistently recognized when using (long,) 100 msec delays. The delays in this commit are nominal (10 & 40 msec) and need testing/tuning on boards with I2C problems to find the right values.
