+# Getting started PWM1 with DC servo motor on mbed OS
+
+
+### Import NuMaker-mbed-PWM1_DCservo from on-line IDE
+1. Please choose Nuvoton NuMaker-PFM-XXX as your target platform.
+2. Please press the left-up icon "New", then choose "NuMaker PWM1 drive + 5V DC servo motor" from the template list.
+3. Your NuMaker-mbed-PWM1_DCservo program is existed.
+
+#### Now compile
+Please press compile icon.
+
+#### Burn Code & Execute
+1. Connect the board NuMaker-PFM-XXX with your PC by USB cable, then there will be one "mbed" disk.
+2. Copy the built binary file into "mbed" disk on you PC.
+3. Press device's reset button to execute, and you could get the below log by uart console.
+-------------------------------------------------------------------------------
+...DCserv Start...
+DCservo pulse width = 500
+DCservo pulse width = 700
+
+		:
+		:
+...DCserv End.....
+--------------------------------------------------------------------------
