#%TITLE% HBM2.MAC
#%NAME%
# Macros to control the Hbm 2 channels equipement (MGC)
#
#%AUTHOR% MCD
#
#%CATEGORY% Positioning
#
#%DESCRIPTION%
# These macros allow to initialize, read this type of encoder, and
# define them as pseudomotors.
#%DEPENDENCIES%
# To use an HBM encoder:
#%UL%
#%LI% load the macro file : hbm2.mac
#%LI% setup the encoder(s) : with hbmsetup
#%LI% configure your encoder(s) :
#%UL%
#%LI% controller NONE
#%LI% mnemonic corresponding to the one provided in hbmsetup
#%XUL%
#%XUL%
# For the following macros, the HBM_DEV_index
# represents the index 0..n in the list of
# HBM devices defined by the user with hbmsetup
# if this parameter is omitted, as it is always
# the last parameter in the list of the macro,
# Spec will replace it by 0. So omitting it
# allows to work to the first HBM of the list.
#%END%
# $Revision: 3.1 $
#
# NOTE: For the following macros, the HBM_DEV_index
# represents the index 0..n in the list of
# HBM devices defined by the user with hbmsetup
# if this parameter is omitted, as it is always
# the last parameter in the list of the macro,
# Spec will replace it by 0. So omitting it
# allows to work to the first HBM of the list.
#
# hbm_quit HBM_DEV_index
#
# frees the connection with the serial line for
# one device
#
# hbm_cmd cmd HBM_DEV_index
#
# sends the set of caracters `cmd' to one device
#
# hbm_init HBM_DEV_index
#
# initialises the connection with one device
#
# hbm_flush HBM_DEV_index
#
# reads what is on the serial line buffer for
# one device
#
# hbm_read HBM_DEV_index
#
# print the position value of one device
# It puts also this value in HBM_VAL
#
# hbm_read3 mne HBM_DEV_index
#
# for pseudo motor mecanism, reads the value
# of one pseudo motor
# It puts also this value in HBM_VAL

#%BR% This macro allows to define some HBM encoders as pseudomotors.
#%BR% For each encoder, the user has to provide the mnemonic for this
# encoder (free), plus the server device name for the hardware
# access to the encoder. Each encoder has a number, from 0 to
# [nb of hbm]-1.
