+## method 1
+Generate libdriver.a in SDK/lib, in driver_lib folder, run:
+
+    ./make_lib.sh driver
+
+## method 2
+* STEP 1: 
+
+    Copy driver folder to your project sub-folder, such as app folder. Unused drivers can be removed in your project.
+
+* STEP 2: 
+
+    Modify Makefile in app folder.
+
+    1). Search SUBDIRS, add driver as subdir, such as:
+
+        SUBDIRS = user driver
+
+    2). Search COMPONENTS_eagle.app.v6, add libdriver.a, such as:
+
+        COMPONENTS_eagle.app.v6 = user/libuser.a driver/libdriver.a
