Hi
I'm using external RTC which has DS1307 where it communicates to my cc3200 using (SDA and SCL) I2C. Please note as oer block diagram there are two I2C interface available in cc3200 LP
I'm using RTC lib specified for ds1307 from here
Option #1: when I connect my RTC module to Pin P01 and P02 (SCL and SDA) as detailed in CC3200 block diagram I see valid clock/time in my COM port
Option #2: Now, When I try the with other I2C port in P4 40 and 39 (top two pins) I'm not seeing any clock/timer value
Please help me to understand what might be the reason? why one I2C interface works w
