Hi, I succesfully tested demo programs related to analog IO but digital IO is not working. Calling to "comedi_config /dev/comedi0 daqboard2000" generates in the kernel log the following: Feb 22 18:11:59 imi kernel: comedi0: daqboard2000: ids2daqboard2000_resetLocalBus Feb 22 18:11:59 imi kernel: daqboard2000_reloadPLX Feb 22 18:11:59 imi kernel: daqboard2000_pulseProgPin 1 Feb 22 18:11:59 imi kernel: daqboard2000_resetLocalBus Feb 22 18:11:59 imi kernel: daqboard2000_reloadPLX Feb 22 18:11:59 imi kernel: 8255 support not configured -- disabling subdevice Feb 22 18:11:59 imi kernel: and the test program "info" from comedilib/demo yields this output: [root_at_imi demo]# ./info overall info: version code: 0x010000 driver name: daqboard2000 board name: ids2 number of subdevices: 3 subdevice 0: type: 1 (analog input) number of channels: 24 max data value: 65535 ranges: all chans: [-10,10] [-5,5] [-2.5,2.5] [-1.25,1.25] [-0.625,0.625] [-0.3125,0.3125] [-0.156,0.156] [0,10] [0,5] [0,2.5] [0,1.25] [0,0.625] [0,0.3125] command: not supported subdevice 1: type: 2 (analog output) number of channels: 2 max data value: 65535 ranges: all chans: [-10,10] command: not supported subdevice 2: type: 0 (unused) My problem is that the subdevice 2 (digital IO is not enabled). Where sould I configure support for the 8255? RedHat 9 with vanilla kernel 2.4.20 comedi 0.7.67 comedilib 0.7.21 Thanks in advance Alfonso Fernandez
