| firmware reported by the mouse. Using the integer value eases | ||
| further usage in other programs. To receive the real version | ||
| number the decimal point has to be shifted 2 positions to the | ||

| Kernel driver ds620 | ||
| =================== | ||
|
|
||
| Supported chips: | ||
| * Dallas Semiconductor DS620 | ||
| Prefix: 'ds620' | ||
| Datasheet: Publicly available at the Dallas Semiconductor website | ||
| http://www.dalsemi.com/ | ||
|
|
||
| Authors: | ||
| Roland Stigge <stigge@antcom.de> | ||
| based on ds1621.c by | ||
| Christian W. Zuckschwerdt <zany@triq.net> | ||
|
|
||
| Description | ||
| ----------- | ||
|
|
||
| The DS620 is a (one instance) digital thermometer and thermostat. It has both | ||
| high and low temperature limits which can be user defined (i.e. programmed | ||
| into non-volatile on-chip registers). Temperature range is -55 degree Celsius | ||
| to +125. Between 0 and 70 degree Celsius, accuracy is 0.5 Kelvin. The value | ||
| returned via sysfs displays post decimal positions. | ||
|
|
||
| The thermostat function works as follows: When configured via platform_data | ||
| (struct ds620_platform_data) .pomode == 0 (default), the thermostat output pin | ||
| PO is always low. If .pomode == 1, the thermostat is in PO_LOW mode. I.e., the | ||
| output pin PO becomes active when the temperature falls below temp1_min and | ||
| stays active until the temperature goes above temp1_max. | ||
|
|
||
| Likewise, with .pomode == 2, the thermostat is in PO_HIGH mode. I.e., the PO | ||
| output pin becomes active when the temperature goes above temp1_max and stays | ||
| active until the temperature falls below temp1_min. | ||
|
|
||
| The PO output pin of the DS620 operates active-low. |

| Kernel driver sht21 | ||
| =================== | ||
|

||
| Supported chips: | ||
| * Sensirion SHT21 | ||
| Prefix: 'sht21' | ||

| Description | ||
| ----------- | ||
|
|
||
| The SHT21 and SHT25 are humidity and temperature sensors in a DFN package of | ||
| only 3 x 3 mm footprint and 1.1 mm height. The difference between the two | ||
| devices is the higher level of precision of the SHT25 (1.8% relative humidity, | ||
| 0.2 degree Celsius) compared with the SHT21 (2.0% relative humidity, | ||
| 0.3 degree Celsius). | ||
|
|
||
| The devices communicate with the I2C protocol. All sensors are set to the same | ||
| I2C address 0x40, so an entry with I2C_BOARD_INFO("sht21", 0x40) can be used | ||
| in the board setup code. | ||

|
||
| Notes | ||
| ----- | ||
|
|
||
| The driver uses the default resolution settings of 12 bit for humidity and 14 | ||
| bit for temperature, which results in typical measurement times of 22 ms for | ||
| humidity and 66 ms for temperature. To keep self heating below 0.1 degree | ||
| Celsius, the device should not be active for more than 10% of the time, | ||
| e.g. maximum two measurements per second at the given resolution. | ||
|
|
||
| Different resolutions, the on-chip heater, using the CRC checksum and reading | ||
| the serial number are not supported yet. |
