There are +alarms for high, low, and critical thresholds. There's also an hysteresis to +control the thresholds for resetting alarms. + +Support was added later for the LM76 and Maxim MAX6633/MAX6634/MAX6635, +which are mostly compatible. They have not all been tested, so you +may need to use the force parameter. |
