Hello,

In cortex ARM M-3 (FO and F3) we can use I�C mode until 1MHz, but not with STM32F407. Somebody do you know why ? Clock is faster than F3 series so for me is possible.

#i2c-f4-1mhz

FM+ mode (I2C up to 1MHz) is available in STM32F446.

The availability of this mode doesn't depend on the use core:

- F3: Cortex-M4

- F0: Cortex-M0

- F4: Cortex-M4

Hello,

thanks for your answer. Is it possible to implements FM+ in STM32F04 despite ? II don't see any hardware limitations
