Subject: [lm-sensors] ncpXXxh103 compensation values?
Date: Wed, 30 Mar 2016 14:03:41 +0000 [thread overview]
Message-ID: <56FBDCBD.7080802@gmail.com> (raw)
Hello Joseph,
You recently added support for the ncpXXxh103 in
drivers/hwmon/ntc_thermistor.c with the following array of values:
+static const struct ntc_compensation ncpXXxh103[] = {
+ { .temp_c = -40, .ohm = 247565 },
+ { .temp_c = -35, .ohm = 181742 },
+ { .temp_c = -30, .ohm = 135128 },
+ { .temp_c = -25, .ohm = 101678 },
+ { .temp_c = -20, .ohm = 77373 },
+ { .temp_c = -15, .ohm = 59504 },
+ { .temp_c = -10, .ohm = 46222 },
+ { .temp_c = -5, .ohm = 36244 },
+ { .temp_c = 0, .ohm = 28674 },
+ { .temp_c = 5, .ohm = 22878 },
+ { .temp_c = 10, .ohm = 18399 },
+ { .temp_c = 15, .ohm = 14910 },
+ { .temp_c = 20, .ohm = 12169 },
+ { .temp_c = 25, .ohm = 10000 },
+ { .temp_c = 30, .ohm = 8271 },
+ { .temp_c = 35, .ohm = 6883 },
+ { .temp_c = 40, .ohm = 5762 },
+ { .temp_c = 45, .ohm = 4851 },
+ { .temp_c = 50, .ohm = 4105 },
+ { .temp_c = 55, .ohm = 3492 },
+ { .temp_c = 60, .ohm = 2985 },
+ { .temp_c = 65, .ohm = 2563 },
+ { .temp_c = 70, .ohm = 2211 },
+ { .temp_c = 75, .ohm = 1915 },
+ { .temp_c = 80, .ohm = 1666 },
+ { .temp_c = 85, .ohm = 1454 },
+ { .temp_c = 90, .ohm = 1275 },
+ { .temp_c = 95, .ohm = 1121 },
+ { .temp_c = 100, .ohm = 990 },
+ { .temp_c = 105, .ohm = 876 },
+ { .temp_c = 110, .ohm = 779 },
+ { .temp_c = 115, .ohm = 694 },
+ { .temp_c = 120, .ohm = 620 },
+ { .temp_c = 125, .ohm = 556 },
+};
+
Where are these taken from?
Unlike the other thermistors in the file, these values don't seem to
match anything in the Murata NTC Thermistor Datasheet.
