The Sample code source you can download from

Source file:

<Google Drive> F81801U_HW_Src

<FTP> F81801U_HW_Src

About source code.

1.Install libgtk2.0-dev first

2.We suggest using Code::Blocks as an IDE in Linux.

3.Or you can just use "make" to compile the source code in the f81801u_hw_src/ folder or f81801u_hw_src/src/ folder.
  And you can excute "f81801u_hw" file in the f81801u_hw_src/src/ folder
 $cd f81801u_hw_src
 $./configure
 $make
 $src/f81801u_hw
 or double click f81801u_hw

If you want to execute the hardware monitor utility under user account , you can follow the procedure:

1.Login by user account.

2.go to the f81801u_hw_src/src folder
 $cd f81801u_hw_src/src/

3.copy the f81801u_hw into the ForUser folder
 $cp f81801u_hw ForUser

4.build SetForUser
 $gcc -o f81801u_hw SetForUser.c

5.change the file mode
 $sudo chown root.root f81801u_hw
 $sudo chmod 4755 f81801u_hw

6.then you can execute the hardware monitor utility
 $./f81801u_hw 
 or double click f81801u_hw

Binary file:

<Google Drive> F81801U_HW_Bin

<FTP> F81801U_HW_Bin

How to use the DEMO application

1. Press the "Read Value" button , and then you can find the values in the below text boxes.
