LPCopen 2.x and USB Mass Storage??

Hi all,

After a six years break, I just started playing around with LPCs. On my desk I have a LPC11u68 board (and also a 1769 one).

I'd like to implement mass storage (MSC) functionality into my firmware. However, I can not find any up-to-date sample code.
The latest thing I found so far is the code example provided by version 1.03 (unfortunately for the wrong chip)... For a beginner, like me, it is very hard to migrate this code (chip AND lpcopen version). Especially when you have read post like this: http://www.lpcware.com/content/forum/hw-init-and-hw-getmemsize-return-seemingly-incorrect-values#comment-1131480

Can you please point me to the correct USB MSC demo implementation :~

Is it possible to have a MSC running in parallel with a CDC at the same chip? That is so to say "two USB devices at once"

Thanks in advance,
Juergen

You can find the current LPCOpen (v2) examples at:

http://www.lpcware.com/lpcopen

and the specific packages for the parts you mention at:

Hi,

Of course, I have already downloaded the LPC11U68 libs. The problem is that there are no mass storage device examples included. I also downloaded several libs for other processors/boards. The closest thing I found was a mass storage HOST example in the 1769 libs. However, I need a up-to-date DEVICE example.

Thanks,
Juergen

Hi Juergen,

Our apologies on missing the USB MSC Device example for LPC11U68. We will get this updated in the next few days.

Best regards,

Hello Juergen,
Please see the attachment below for the Mass storage example that runs on LPC11U6x Xpresso board. You can import the archive into a LPCXpresso (recommended v7.3.0) workspace. [If you have existing LPC11u6x workspace import only the msc_ram project, and deselect board and chip library project during import, if you are importing into a fresh workspace you can import all the three and can build and run msc_ram project].

NOTE: This example will be part of next LPCOpen release for LPC11U6x boards.

If you are looking for a composite USB device, please look into the usbd_rom_composite example which you can find inside the LPCOpen package available from lpcware.com [This example shows how to use mouse and cdc vcom device as composite usb device]

Thanks and Regards,
Sundar.

Hi Sundar,

this is exactly what I was looking for. Thank you very much.

Regards,
Juergen

BTW: I can't use v7.3.0 on my OSX. LPCXpresso does not find the debug hardware. In v7.2.0 everything works fine. Maybe I missed something during the update process...
