URGENT MATTER:
We are a senior design team working on the design of a MPPT charge controller. We are using the SM72442 and the MSP430G2553 launchPad to read out the values from the charge controller. When we run our i2c code we do not get an acknowledge bit from the SM72442. We are attaching the schematic of the configuration used only for communicating with the MSP430 via I2C. In addition we have attached the screenshot from our oscilloscope displaying the clock (Yellow line) and data (Blue line) lines, but the SM72442 does not respond. we have reviewed the datasheet and carefully read page 13 for I2C communication. below is the link of the PDF for the SM72442.

Our address is: 0x07, and our I2C0=1; I2C1=1; I2C2=1
Please we do appreciate a prompt response, due that we are running out of time for the deadline of our project.
Thanks,
Andrea Solano
