| 32 | DRIVER NOTES: |
| 33 | |
| 34 | Installation is simple, you only need to add Linux Input, Linux USB, and the |
| 35 | driver to the kernel. The driver can also be optionally built as a module. |
| 36 | |
| 37 | This driver appears to be one of possible 2 Linux USB Input Touchscreen |
| 38 | drivers. Although 3M produces a binary only driver available for |
| 39 | download, I persist in updating this driver since I would like to use the |
| 40 | touchscreen for embedded apps using QTEmbedded, DirectFB, etc. So I feel the |
| Matt LaPlante | 2fe0ae7 | 2006-10-03 22:50:39 +0200 | [diff] [blame] | 41 | logical choice is to use Linux Input. |
| Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 42 | |
| 43 | Currently there is no way to calibrate the device via this driver. Even if |
| 44 | the device could be calibrated, the driver pulls to raw coordinate data from |
| 45 | the controller. This means calibration must be performed within the |
| 46 | userspace. |
| 47 | |
| 48 | The controller screen resolution is now 0 to 16384 for both X and Y reporting |
| 49 | the raw touch data. This is the same for the old and new capacitive USB |
| 50 | controllers. |
| 51 | |
| 52 | Perhaps at some point an abstract function will be placed into evdev so |
| 53 | generic functions like calibrations, resets, and vendor information can be |
| 54 | requested from the userspace (And the drivers would handle the vendor specific |
| 55 | tasks). |

| 61 | TODO: |
| 62 | |
| 63 | Implement a control urb again to handle requests to and from the device |
| 64 | such as calibration, etc once/if it becomes available. |

| 68 | I am not a MicroTouch/3M employee, nor have I ever been. 3M does not support |
