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
