Kernel driver `ds1621.o' ===================== Status: Complete and tested, alarms experimental Supported chips: * Dallas Semiconductor DS1621 Prefix: `ds1621' Addresses scanned: I2C 0x48 - 0x4f (inclusive) Datasheet: Publicly available at the Dallas Semiconductor website http://www.dalsemi.com Author: Christian W. Zuckschwerdt Module Parameters ----------------- * force: short array (min = 1, max = 48) List of adapter,address pairs to boldly assume to be present * force_ds1621: short array (min = 1, max = 48) List of adapter,address pairs which are unquestionably assumed to contain a `ds1621' chip * ignore: short array (min = 1, max = 48) List of adapter,address pairs not to scan * ignore_range: short array (min = 1, max = 48) List of adapter,start-addr,end-addr triples not to scan * probe: short array (min = 1, max = 48) List of adapter,address pairs to scan additionally * probe_range: short array (min = 1, max = 48) List of adapter,start-addr,end-addr triples to scan additionally Description ----------- The DS1621 implements one temperature sensor. Limits can be set through the Overtemperature register and Hysteresis register. Each value can be set and read to half-degree accuracy. An alarm is issued when the temperature gets higher then the Overtemperature value; or drops below the Hysteresis value. It stays on until reset by the kernel module. All temperatures are in degrees Celcius, and are guaranteed within a range of -55 to +125 degrees. The DS1621 supplies the temperature data in a format common with chips like the LM75, LM77 and DS75, DS1775. While the DS1621 has three additional bits of accuracy (12 vs. 9 for the LM75), the additional bits are not supported.
