void EthercatHardware::changeState ( EtherCAT_SlaveHandler *  sh,
EC_State  new_state 
) [static, private]

Definition at line 103 of file ethercat_hardware.cpp.

Collects diagnotics from all devices.

Definition at line 905 of file ethercat_hardware.cpp.

EthercatDevice * EthercatHardware::configNonEthercatDevice ( const std::string &  product_id,
const std::string &  data 
) [private]

void EthercatHardware::haltMotors ( bool  error,
const char *  reason 
) [private]

Definition at line 657 of file ethercat_hardware.cpp.

void EthercatHardware::init ( char *  interface,
bool  allow_unprogrammed 
)

Initialize the EtherCAT Master Library.

Parameters:
interfaceThe socket interface that is connected to the EtherCAT devices (e.g., eth0)
allow_unprogrammedA boolean indicating if the driver should treat the discovery of unprogrammed boards as a fatal error. Set to 'true' during board configuration, and set to 'false' otherwise.

Definition at line 838 of file ethercat_hardware.cpp.

void EthercatHardware::printCounters ( std::ostream &  os = std::cout)

Definition at line 940 of file ethercat_hardware.cpp.

Collects raw diagnostics data and passes it to diagnostics_publisher.

Definition at line 688 of file ethercat_hardware.cpp.

bool EthercatHardware::publishTrace ( int  position,
const string &  reason,
unsigned  level,
unsigned  delay 
)

Ask one or all EtherCAT devices to publish (motor) traces.

Parameters:
positiondevice ring position to publish trace for. Use -1 to trigger all devices.
reasonMessage to put in trace as reason.
levelLevel to put in trace (aka ERROR=2, WARN=1, OK=0)
delayPublish trace after delay cyles. For 1kHz realtime loop 1cycle = 1ms.
Returns:
Return true if device supports publishing trace. False, if not. If all devices are triggered, returns true if any device publishes trace.

Definition at line 982 of file ethercat_hardware.cpp.

bool EthercatHardware::txandrx_PD ( unsigned  buffer_size,
unsigned char *  buffer,
unsigned  tries 
)

Send process data.

Definition at line 965 of file ethercat_hardware.cpp.

void EthercatHardware::update ( bool  reset,
bool  halt 
)

Send most recent motor commands and retrieve updates. This command must be run at a sufficient rate or else the motors will be disabled.

Parameters:
resetA boolean indicating if the motor controller boards should be reset
haltA boolean indicating if the motors should be halted
