40 | Driver Notes |
| 41 | ============ | |
| 1da177e4 | 42 | |
| d80b5005 | 43 | Installation is simple, you only need to add Linux Input, Linux USB, and the |
| 1da177e4 LT |
44 | driver to the kernel. The driver can also be optionally built as a module. |
| 45 | ||
| 46 | This driver appears to be one of possible 2 Linux USB Input Touchscreen | |
| 47 | drivers. Although 3M produces a binary only driver available for | |
| 48 | download, I persist in updating this driver since I would like to use the | |
| 49 | touchscreen for embedded apps using QTEmbedded, DirectFB, etc. So I feel the | |
| 2fe0ae78 | 50 | logical choice is to use Linux Input. |
| 1da177e4 LT |
51 | |
| 52 | Currently there is no way to calibrate the device via this driver. Even if | |
| 53 | the device could be calibrated, the driver pulls to raw coordinate data from | |
| 54 | the controller. This means calibration must be performed within the | |
| 55 | userspace. | |
| 56 | ||
| 57 | The controller screen resolution is now 0 to 16384 for both X and Y reporting | |
| 58 | the raw touch data. This is the same for the old and new capacitive USB | |
| 59 | controllers. | |
| 60 | ||
| d80b5005 MCC |
61 | Perhaps at some point an abstract function will be placed into evdev so |
| 62 | generic functions like calibrations, resets, and vendor information can be | |
| 1da177e4 LT |
63 | requested from the userspace (And the drivers would handle the vendor specific |
| 64 | tasks). | |
| 65 | ||
| d80b5005 MCC |
66 | TODO |
| 67 | ==== | |
| 1da177e4 LT |
68 | |
| 69 | Implement a control urb again to handle requests to and from the device | |
| 70 | such as calibration, etc once/if it becomes available. | |

72 | Disclaimer |
| 73 | ========== | |
| 1da177e4 | 74 | |
| d80b5005 | 75 | I am not a MicroTouch/3M employee, nor have I ever been. 3M does not support |
| 1da177e4 LT |
76 | this driver! If you want touch drivers only supported within X, please go to: |
