I2C Multi Master Communication in LPC55S69JBD100 EVK Board

Nikhil_Gupta — Tue, 28 Jan 2025 14:00:36 GMT

Hello All,

I'm working on LPC55S69JBD100EVK Board Controller for I2C Multi Master Communication,

While switching from Master to Slave and vice versa, there is no communication or data in between.

But when I checked individually its working fine(Master to slave).

I need in detail flow how to achieve this Multi Master communication with out any conflicts.

Note:- I'm Using two EVK boards, for master(FLEXCOMM1) and slave(FLEXCOMM4) in one board, another board(FLEXCOMM1) this should keep mode switching when required.

Thank you in advance.

Regards,

Nikhil

Hello @Nikhil_Gupta

Sorry for replying to you late. I just got back from the Chinese New Year holiday. Maybe your issue has been solved. If not, please check the SCL signal after the switch.

Thank you!

Alice
