svdoshi 0 Posted January 16, 2015 Share Posted January 16, 2015 Hello Guys, I am using I2C communication to talk to the RTC chip(Real time clock). I am using this code for it http://wiring.org.co/learning/libraries/realtimeclock.html. I am using Wire library given by Ti. For some reason it hangs at Wire.endTransmission(). Would you have any insight on that? Thanks for your support!! Happy Friday! Quote Link to post Share on other sites
