Hi all,

I'm facing a problem with the implementation of a double Own address on a STM32F030K6T6 uC. the project is already working but with only 1 Own address on OAR1 (code 42 hex), now I want to update the project to enable the reception of another code (52 hex) on OAR2 but there's something wrong on the matching address of the i2c hardware of ST I think, because it seem that hide OAR1 and made priority to OAR2. It is possible? 

Thnaks.

Yes, it's possible. The address in the OA2 field is ACKed if OA2EN is set.
