Macro Definition Documentation

◆ MAX31865_CFG_1SHOT

#define MAX31865_CFG_1SHOT (0b00100000)

Trigger a single conversion.

The automatic conversion mode must be off. Single conversion time is 52ms in 60Hz or 62.5ms in 50Hz filter mode.

Definition at line 94 of file max31865_internal.h.

◆ MAX31865_CFG_3WIRE

#define MAX31865_CFG_3WIRE (0b00010000)

3-wire resistor connection

Clear the bit for 2- or 4-wire connections.

Definition at line 101 of file max31865_internal.h.

◆ MAX31865_CFG_CLEAR_FAULT

#define MAX31865_CFG_CLEAR_FAULT (0b00000010)

Clear fault condition.

Definition at line 106 of file max31865_internal.h.

◆ MAX31865_CFG_CONV_AUTO

#define MAX31865_CFG_CONV_AUTO (0b01000000)

Enable automatic conversion mode.

The conversion rate is the same as the selected filter mode, i.e. either 50 or 60Hz.

Definition at line 86 of file max31865_internal.h.

◆ MAX31865_CFG_FILTER_50HZ

#define MAX31865_CFG_FILTER_50HZ (0b00000001)

Filter out 50Hz if set, or 60Hz otherwise.

Clear the bit for 60Hz filter mode.

Definition at line 113 of file max31865_internal.h.

◆ MAX31865_CFG_FLTDET_AUTO_START

#define MAX31865_CFG_FLTDET_AUTO_START (0b00000100)

Start a fault detection with an automatic delay (about 550µs)

Definition at line 134 of file max31865_internal.h.

◆ MAX31865_CFG_FLTDET_IDLE

#define MAX31865_CFG_FLTDET_IDLE (0b00000000)

No fault detection is running.

Definition at line 129 of file max31865_internal.h.

◆ MAX31865_CFG_FLTDET_MANU_START

#define MAX31865_CFG_FLTDET_MANU_START (0b00001000)

Start a fault detection with a manually controlled delay.

Definition at line 139 of file max31865_internal.h.

◆ MAX31865_CFG_FLTDET_MANU_STOP

#define MAX31865_CFG_FLTDET_MANU_STOP (0b00001100)

Terminate fault detection with a manually controlled delay.

Definition at line 144 of file max31865_internal.h.

◆ MAX31865_CFG_FLTDET_MASK

#define MAX31865_CFG_FLTDET_MASK (0b00001100)

Fault detection bit mask.

To check the status of the fault detection cycle, mask the bits of the configuration register and compare the value with MAX31865_CFG_FLTDET_IDLE, MAX31865_CFG_FLTDET_AUTO_START, MAX31865_CFG_FLTDET_MANU_START or MAX31865_CFG_FLTDET_MANU_START.

Definition at line 124 of file max31865_internal.h.

◆ MAX31865_CFG_VBIAS_ON

#define MAX31865_CFG_VBIAS_ON (0b10000000)

Enable Vbias.
