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. |
