Is there a non-polling version of HAL_I2C_IsDeviceReady?

I am looking for an interrupt based replacement for HAL_I2C_IsDeviceReady. I am implementing a EEPROM library for M24256 I2C Serial EEPROM in a FreeRTOS application.  The call HAL_I2C_IsDeviceReady relies on polling for many milliseconds to perform this function. Is there a version written to use interrupts?

Hello @nonesuchoudon​ ,

There is only a polling version of HAL_I2C_IsDeviceReady.

This function is used with Memory devices.

(DevAddress Target device address: The device 7 bits address value in datasheet must be shifted to the left before calling the interface).
