Cannot interface SHT25 to STM32F4239I-DISC1 board BY I2C3.

[Madhusudan]

Hi there,

I have made the touch project by touchgfx and initiated the I2C3 by cubemx.

I am interfacing the SHT25 with STM32F4239I-DISC1 board BY I2C3. PA8 AND PC9.

I am using the command HAL_I2C_Master_Transmit and HAL_I2C_Master_Receive. but I cannot get the values from the protocol. Any help is required.

The Sensirion is almost a normal I2C device, should work just fine with STM32.

HAL_I2C_Mem_Read to read registers, HAL_I2C_Master_Receive to read data.
