Detailed Description

This class provides low-level functions for reading and writing from the SPI interface of a DRV8434S stepper motor controller IC.

Most users should use the HighPowerStepperDriver class, which provides a higher-level interface, instead of this class.

Member Function Documentation

readReg() [1/2]

uint16_t DRV8434SSPI::readReg ( DRV8434SRegAddr  address )

inline

Reads the register at the given address and returns its raw value.

Definition at line 71 of file DRV8434S.h.

readReg() [2/2]

uint8_t DRV8434SSPI::readReg ( uint8_t  address )

inline

Reads the register at the given address and returns its raw value.

Definition at line 56 of file DRV8434S.h.

setChipSelectPin()

void DRV8434SSPI::setChipSelectPin ( uint8_t  pin )

inline

Configures this object to use the specified pin as a chip select pin.

You must use a chip select pin; the DRV8434S requires it.

Definition at line 48 of file DRV8434S.h.

writeReg() [1/2]

void DRV8434SSPI::writeReg ( DRV8434SRegAddr  address, uint8_t  value  )

inline

Writes the specified value to a register.

Definition at line 94 of file DRV8434S.h.

writeReg() [2/2]

uint8_t DRV8434SSPI::writeReg ( uint8_t  address, uint8_t  value  )

inline

Writes the specified value to a register.

Definition at line 77 of file DRV8434S.h.

Member Data Documentation

lastStatus

uint8_t DRV8434SSPI::lastStatus = 0

The status reported by the driver during the last read or write. This status is the same as that which would be returned by reading the FAULT register with DRV8434S::readFault(), except the upper two bits are always
