Enumeration Type Documentation

enum EDC_COMMAND

The host can request different types of data from the palm.

Enumerator:

EDC_COMMAND_INVALID	Reading an empty mailbox on the ET1200 results in a zero.
EDC_COMMAND_SENSOR_DATA	Normal operating value. Palm transmits ADC readings.
EDC_COMMAND_SENSOR_CHANNEL_NUMBERS	Instead of sending ADC readings, send the channel number, so the host can confirm the firmware is correct.
EDC_COMMAND_SENSOR_ADC_CHANNEL_CS	Instead of sending ADC readings, send the chip select channel, so the host can confirm the firmware is correct.
EDC_COMMAND_CAN_DIRECT_MODE	Might be used in the future for running automated tests inside the firmware.

Definition at line 48 of file common_edc_ethercat_protocol.h.

enum HARD_CONFIGURATION_INFORMATION

Enumerator:

PALM_SVN_VERSION
SERVER_SVN_VERSION

Definition at line 163 of file common_edc_ethercat_protocol.h.

enum MESSAGE_DIRECTION

This represents the top two bits [10..9] of the CAN message ID. These bits tell us the type of the message.

Enumerator:

DIRECTION_DATA_REQUEST	Requesting that motors send back status data (AKA Start of Frame)
DIRECTION_TO_MOTOR	Message contains command data being sent to the motors.
DIRECTION_FROM_MOTOR	Message contains status data from a motor.
DIRECTION_BOOTLOADER	Message has something to do with boot-loading.
