Hi,
I'm also having a performance problem with the I2c on the Galileo using the Arduino sketches to make calls with the Wire library. Is there a way to make the system(linux) calls with the Arduino IDE, that can setup and make the read and write calls, to improve the performance of i2c back to its normal speeds and perhaps faster like 400 kHz? I want to have it talk to an adafruit i2c pwm servo driver, and its crawling along in its normal mode. thanks for for any help on this.
best,
Steve
