I'm currently using a STM32 Nucleo-G071RB, I am trying to connect to a DAC (MCP4725) and also to a MLX90393 both using I2C, the DAC is connecting fine, but I am getting nothing from the MLX90393, has anyone used this device and been able to get anything back?

Hello @JNava.3 , 

Make sur that you are using the right address and respecting the max frequency.
To check if target device is ready for communication, use the function HAL_I2C_IsDeviceReady()
Take an oscilloscope to check SDA and SCL behavior.
