some code for review
rayl
in an effort to make the existing code a little easier to understand
and hack on, i've ported some of the stuff i did in libfprint to
vfs101driver. the code is sitting here:
git://github.com/rayl/vfs101driver.git rayl
with this version, you can write code like this:
static int test_case_1 (struct vfs_dev *dev)
{
_( GetVersion(dev));
_( GetConfiguration(dev));
_( try_something(dev));
_( Peek(dev, 0x00009806, 0x04));
_( Poke(dev, 0x00009806, 0x12345678, 0x04));
_( Peek(dev, 0x00009806, 0x04));
_( try_something_else(dev));
return 0;
}
static int try_something (struct vfs_dev *dev)
{
_( GetParam(dev, 0x14));
struct set_param p1[] = {
{ 0x0005, 0x0000 },
{ 0x0006, 0x0000 },
{ 0x0007, 0x0000 },
{ 0x000A, 0x0002 },
};
_( SetParamList(dev, p1, nitems(p1)));
_( GetPrint(dev, 2, type_0));
_( LoadImage(dev));
return 0;
}
static int try_something_else (struct vfs_dev *dev)
{
_( GetParam(dev, 0x11));
_( SetParam(dev, 0x0062, 0x0032));
_( GetPrint(dev, 5000, type_1));
_( LoadImage(dev));
return 0;
}
then you can call test_case_1() and get output like this:
Libusb inititalized!
Searching for device...
Device found!
Checking active kernel driver...
Claiming interface...

Resetting device...
Configuring device...

Main cycle complete success!
hopefully this will make it easier to experiment with different
protocol variations.
any feedback is welcome
