| 37 | Description |
|---|
| 38 | ----------- |
|---|
| 39 | |
|---|
| 40 | The W83L785TS-S is a digital temperature sensor. It senses the |
|---|
| 41 | temperature of a single external diode. The high limit is |
|---|
| 42 | theoretically defined as 85 or 100 degrees C through a combination |
|---|
| 43 | of external resistors, so the user cannot change it. Values seen so |
|---|
| 44 | far suggest that the two possible limits are actually 95 and 110 |
|---|
| 45 | degrees C. The datasheet is rather poor and obviously inaccurate |
|---|
| 46 | on several points including this one. |
|---|
| 47 | |
|---|
| 48 | All temperature values are given in degrees Celsius. Resolution |
|---|
| 49 | is 1.0 degree. See the datasheet for details. |
|---|
| 50 | |
|---|
| 51 | The w83l785ts driver will not update its values more frequently than |
|---|
| 52 | every other second; reading them more often will do no harm, but will |
|---|
| 53 | return 'old' values. |
|---|
| 54 | |
|---|
| 55 | |
|---|
| 56 | Known Issues |
|---|
| 57 | ------------ |
|---|
| 58 | |
|---|
| 59 | On some systems (Asus), the BIOS is known to interfere with the driver |
|---|
| 60 | and cause read errors. The driver will retry a given number of times |
|---|
| 61 | (5 by default) and then give up, returning the old value (or 0 if |
|---|
| 62 | there is no old value). It seems to work well enough so that you should |
|---|
| 63 | not notice anything. Thanks to James Bolt for helping test this feature. |
