Part Number: CC2543

Hello,

I am trying to integrate a MEMS sensor (LIS2DE12) with CC2543 over I2C. To read a register from sensor, below is the activity sequence.

How will I be able generate SR (Repeated Start) signal from CC2543 ?

Hello venugopal,

Please refer to Section 20.1.3.2 (Repeated Start Conditions) of the TRM: The direction of data flow on SDA can be changed by the master, without first stopping a transfer, by issuing a repeated START condition. This is called a RESTART. After a RESTART is issued, the slave address is again sent out with the new data direction specified by the R/W bit.

Regards,
Ryan
