Hello Shay,

The I2C clock frequency per the DLPC900 data sheet is 400 kHz. The structure is shown in section 1.1 of the Programmers Guide [DLPU018].

To the best of my knowledge there is no specified limit to clock stretching period. This is per the I2C protocol specification.

Are you running into an issue with the stretching time?

Hello Shay,

When it does not receive an ACK, I assume that the secondary controller is not configured correctly.

What firmware version is the system reporting?
