Hello,
I did not know where to post and I think that this can be helpful
for the people who work with Windows CE 5.0. Hopefully this e-mail will appear
in the search engines results
The goal is simple - send (and receive) raw
data from Windows CE 5.0 device to the PC
Now problems. The device (WinCE)
does not have FLASH based file system. ActiveSync is not an option, because
of limited resources in the embedded device and lack of portability of the
interface across different host operating systems.
I failed to initialize
storage class device in Win CE 5.0 This is apparently a new feature for Win
CE. Before CE 5.0 MS truly believed that ActiveSync is all a man will ever
need. In Win CE 5.0 Storage Class is officially supported, but still requires
so called file system driver in case of system with only one FLASH device
(here i may be wrong). Long story short - storage class did not work for me.
I chose serial class
You need three things in WinCE
- add USB function
serial class to the components tree in the Platform Builder
- add USB driver
(easy in my case, because BSPs for Intel Xscale ARM already have USB driver)
- add to the file platform.reg lines
