14、NABLED.Serial Port Connection SetupPrior to running any of the C/USB-Host demo(s), a serial port connection should be established to view the output messages through a program capable of viewing Serial Data (such as PuTTY, HyperTerminal, etc.), through the IDEs Terminal I/O Window (if applicable).If

15、 establishing serial output via a program capable of viewing serial data or through the IDEs Terminal I/O window, the following must be configured:Serial Port Connection:1. Setup the serial port connection and connect the serial port to the appropriate serial port on the STM3240G-EVAL.2. Use PuTTY,

16、HyperTerminal, or any other program with the ability to display serial port communication with the following data:a. COM # Channel / Serial Line: Based on Host Computer Channel Assignment.i. The COM # channel can be found using the Device Manager in Windows.b. Baud Rate: Based on Project Settings.i.

17、 This value can be usually found in app.c inside the serial initialization function.c. Data Bits: 8d. Parity: Nonee. Stop Bits: 1f. Flow Control: NoneTerminal I/O Connection:For some IDEs, the use of the Terminal I/O connection is available if no serial port is present or configured with the project

18、. Usually, the Terminal I/O is found in the View menu of the IDE. If not, refer to the IDEs documentation for more information.Communication Device Class (CDC) Abstract Control Model (ACM) Subclass DemoThis demo is intended to be used with a USB modem that supports AT commands. Upon connection of th

19、e USB modem to the board, the demo application will initiate a few AT commands and wait for the modems response.1. To run the CDC-ACM class demo, make sure the following definitions found in app_cfg.h are set as follow:ListinC demo(1) In order for the CDC-ACM class demo to run, APP_CFG_USBH_CDC_EN m

22、HomeHuman Interface Device (HID) Class DemoThis demo tests the Mouse and Keyboard demo for the HID class, where the application expects a certain report format that is compatible with the majority of mice and keyboards using the U.S. Layout available on the market. However, there might be a device t

23、hat uses a slightly different report, so the user will have to parse the report differently as well as write it.
