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:
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
