Figure 2-40 Fan rotation speed determination process
Function Block Diagram
Shows the Function block diagram of the AutoFan demonstration. This design has two
main parts. The one is an I2C controller (FAN_TEMP_I2C), which can be used to read the
temperature value of the HAN Pilot Platform Temperature Sensor IC (TMP441) and to set the Fan
Controller IC (MAX6650) register for controlling the fan rotation speed. Both the Temperature
Sensor and the Fan Controller use the same I2C bus. The Temperature Sensor I2C Slave-Address is
0x38, the Fan Controller I2C Slave-Address is 0x90. The other one is a judgment controller
(FAN_ONOFF), which can determine the fan rotation speed value according to the process in
. In this demonstration, you can use the two seven segments to display the FPGA
temperature value and the fan rotation speed value(rpm). All module functions are described as
below:
