+If you're just using the MLX90640 on iic.You can add content that below to the config.txt.
+
+```bash
+dtparam=i2c_arm=on,i2c_arm_baudrate=1000000
+```  
+
+This will give you a framerate of - at most - 32FPS.

+and If you have other iic device ,maybe you can add content that below to the config.txt to get the fastest rate recommended for compatibility

+```bash
+dtparam=i2c_arm=on,i2c_arm_baudrate=400000
