V850ES/Jx3H – Plug it!

11.3 “Jx3-H_PLUGIT_COM” Serial Conversion sample program

The USB serial conversion driver is a communication device class (CDC) sample driver for built-in USB
function controller that is built of the µPD70F3760. It is detected as communication device class (virtual
COM port) when it connects with the host. The sample Application loads the user data received by the USB
function controller and converts it to uppercase characters or to lowercase characters (only ASCII character
data),

and outputs the result on the USB to the virtual COM-Port.
