NAME

       mesa_7i65 - Support for the Mesa 7i65 Octuple Servo Card

SYNOPSIS

       loadrt mesa_7i65

DESCRIPTION

       The  component  takes  parameters  in the form of a comma-separated list of bspi (buffered
       SPI) instance names, for example:

        loadrt mesa_7i65 bspi_chans=hm2_5i23.0.bspi.0, hm2_5i23.0.bspi.1

       The BSPI instances are printed to the dmesg buffer during the Hostmot2 setup sequence, one
       for  each  bspi  instance included in the bitfile loaded to each installed card during the
       Hostmot2 setup sequence. Type "dmesg" at the terminal prompt to view the output.

PINS

       mesa-7i65.N.analogue.M.out float in (M=0..7)
              Analogue output values. The value will be limited to a  -1.0 to +1.0 range

       mesa-7i65.N.analogue.M.in float out (M=0..7)
              Analogue outputs read by the 7i65 (in Volts)

       mesa-7i65.N.digital.M.in bit out (M=0..3)
              Miscellaneous Digital Inputs

       mesa-7i65.N.enable.M.out bit in (M=0..7)
              Amplifier-enable control pins

       mesa-7i65.N.watchdog.has-bit bit out
              Indicates the status of the 7i65 Watchdog (which is separate  from  the  FPGA  card
              watchdog

PARAMETERS

       mesa-7i65.N.scale-M float rw (M=0..7) (default: 10)
              Analogue  output  scale  factor. For example if the scale is 7 then an input of 1.0
              will give 7V on the output terminals

       mesa-7i65.N.is-bipolar-M bit rw (M=0..7) (default: 1)
              Set this value to TRUE for a plus/minus "scale" output. Set to 0  for  a  0-"scale"
              output
