- Driver: s626.o (s626.ko)
- Description: Sensoray 626 driver
- Devices: Sensoray s626
- Authors: Gianluca Palli <gpalli@deis.unibo.it>,
- Updated: Thu, 12 Jul 2005
- Status: experimental
-
- Configuration Options:
- analog input:
- none
-
- analog output:
- none
-
- digital channel:
- s626 has 3 dio subdevices (2,3 and 4) each with 16 i/o channels
- supported configuration options:
- INSN_CONFIG_DIO_QUERY
- COMEDI_INPUT
- COMEDI_OUTPUT
-
- encoder:
- Every channel must be configured before reading.
-
- Example code
-
- insn.insn=INSN_CONFIG; // configuration instruction
- insn.n=1; // number of operation (must be 1)
- insn.data=&initialvalue; // initial value loaded into encoder
- // during configuration
- insn.subdev=5; // encoder subdevice
- insn.chanspec=CR_PACK(encoder_channel,0,AREF_OTHER); // encoder_channel
- // to configure
-
- comedi_do_insn(cf,&insn); // executing configuration
