Currently the driver provides -reporting of all the input values but does not provide any alarms. - -Voltage Monitoring ------------------- - -Voltages are sampled by a 12 bit ADC. Voltages in millivolts are 1.465 -times the ADC value. - -Temperature Monitoring ----------------------- - -Temperatures are sampled by a 12 bit ADC. Chip and battery temperatures -are available. The chip temperature is calculated as: - - Degrees celsius = (512.18 - data) / 1.0983 - -while the battery temperature calculation will depend on the NTC -thermistor component. |
