I was a little surprised when I saw the waves. Datasheet orwnic82 USA #3 Nov 2011 EZ-B || ITG3200 SDA - SDA SCL - SCL GND - GND 3.3V - VDD/VIO Solder contacts together next to CLK for internal CLK DJ Sures PRO Synthiam #4 Nov 2011 Why would you want internal CLK? Isn't the point of i2c to get the clk from the master? orwnic82 USA #5 Nov 2011 For sync reasons between the devices yes however where is the clk signal coming from on the EZ-B then? DJ Sures PRO Synthiam #6 Nov 2011 The EZ-B generates a clk on the SCL. Maybe that is why your scope capture has strageness. Maybe it's because there are conflicting clock signals? Tonight when i get home, i'll scope an i2c communication so you can see what the SCL clock looks like. Hopefully I get my ITG this week too orwnic82 USA #7 Nov 2011 Thats what I was thinking before about the sync when I believed that it might had been reading in the ACK instead. The EZ-B clock needs be same sample speed as the ITG3200. orwnic82 USA #8 Nov 2011 You get your Gyro yet? I really believe their clocks are different which prevents them from syncing. 1 2 3 » »» Login to post a comment
