Hardware: steering wheel and pedals?

[eckzow]

Sorry I haven't been updating you guys on my endeavors with the wheel, but I've got a lot going on that's keeping me away from working on things.

I haven't quite figured out the clutch/shifter yet but I have managed to unlock the full range of the wheel (it can be configured to run from 40 to 900 degrees). Eventually I'll get around to learning the hiddev stuff well enough to integrate that into the driver somehow...

This isn't really the appropriate place for this, but since there seemed to be some technically skilled (enough to recompile a kernel anyway) people here... if anyone cares, unlocking rotation is simple. All you need to do is send 7 bytes to endpoint 1 on the device:

0xf8, 0x81, aa, bb, 0x00, 0x00, 0x00

Where aa, bb is a little-endian unsigned short valued somewhere between 40 and 900. For instance:

char deg40_msg[7] = {0xf8, 0x81, 0x28, 0x00, 0x00, 0x00, 0x00};
char deg900_msg[7] = {0xf8, 0x81, 0x84, 0x03, 0x00, 0x00, 0x00};

Would be the messages to set the soft-stops to 40 and 900 degrees respectively. Currently to do all this I manually unbind the usbhid driver, claim the interface, send the message, and then rebind the usbhid driver.

If anyone has questions or wants help, just post away.
