Hi. Is it possible and if yes, where can i find examples how to communicate with slave devices that work only with Repeated Start instead of Stop when reading them?

Library: Cube F4 V1.3.2

MCU: STM32F429ZI

Hi goncharov.sergey,

Unfortunately this feature does not exist in the current version of STM32Cube F4 package (1.7.0), but it is planned to be added in one of coming releases.

Hi Syrine

I am trying to modify the HAL_I2C_Master_Transmit() to not send STOP condition but instead send a repeated start condition.

From the manual (RM0383 page 472), this seems to be possible when in Master Receiver mode. Is this possible in Master Transmitter mode?

I am using a STM32F411RE.
