STM32F3DISCOVERY USB-Virtual Com Port?

Hi!

May I ask for help about setting up VCP with one?I am currently looking over the files of STM32_USB-FS-Device_Lib_V3.4.0 (under virtual com port). I can't seem to understand how to tailor it with STM32F3Discovery. Or is it even possible to use it with STM32F3? Can anyone help me understand how to use the library with other USB capable STM32's? I am using IAR starter.I am very new to STM32 MCUs. Just opened my STM32F3Discovery this week. I choose this board because of its included sensors. The objective simply to forward the readings of the sensor to a host PC. The data gathered will be used for academic purposes. So, for now, I wanted to connect it first with my PC through VCP.Than you very much.

Also many of the application notes are now the older versions which don't have any mention of F3 in them and they appear under the STM32F3 microcontroller page.

Which ones? May be they are the common ANs. Thanks, ST.MCU

AN4235 was one that seems to disappear into the void. I couldn't find it on the site anywhere, and had to dig it forcibly from Google cached image.  [DEAD LINK /public/STe2ecommunities/mcu/Lists/STM32Discovery/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/STM32Discovery/I2C_Timing_Config_Tool%20for%20F0%20and%20F3&FolderCTID=0x01200200770978C69A1141439FE559EB459D75800084C20D8867EAD444A5987D47BE638E0F&TopicsView=https://my.st.com/public/STe2ecommunities/mcu/Lists/STM32Discovery/AllItems.aspx&currentviews=23]https://my.st.com/public/STe2ecommunities/mcu/Lists/STM32Discovery/Flat.aspx?RootFolder=%2fpublic%2fSTe2ecommunities%2fmcu%2fLists%2fSTM32Discovery%2fI2C_Timing_Config_Tool%20for%20F0%20and%20F3&FolderCTID=0x01200200770978C69A1141439FE559EB459D75800084C20D8867EAD444A5987D47BE638E0F&TopicsView=https%3A%2F%2Fmy.st.com%2Fpublic%2FSTe2ecommunities%2Fmcu%2FLists%2FSTM32Discovery%2FAllItems.aspx¤tviews=23 There is a lot of linkage of the web/google which is now broken as a result of the site change. A lot of stuff either moved or disappeared out of view. I remember Intel tracking 404 errors for referrer information and getting people to fix links. It might be helpful to understand your site metrics to see what people are looking for, and failing.

Hi STOne-32,

The links no longer appear to be valid. Could you post updated links? I am also interested in stm32_vcp.zip, and any documentation that can be found with it. Thanks, L

Thanks, Clive. You're fast.

Hi Clive, I am a newbie in st32 world, and just received st32f3discovery and would like to transfer the gyro data to computer via usb port. i have already managed to read the data off the sensor but couldnt make the usb port work as a com port. if you dont mind, can you give me a sample project if u have, or direct me how to do so. I haven't worked with usb port before at all.

From easy of integration a Virtual Com Port would seem to be the least painful. You would probably want to buffer the output string you create from your device, and then report that data back as coming from the ''com'' port. I would probably start by building the examples in the USB FW library and experiment with them. No, I don't have a prebuilt example for this.

is there template files for the application interace layer (usb_prop,usb_istr..)?? and which part of them we should change??

You should perhaps become familiar with
