This board is a PC-104 based I/O board. It contains -four subdevices: - subdevice 0 - 16 channels of 16-bit AI - subdevice 1 - 8 channels of 16-bit AO - subdevice 2 - first 24 channels of the 48 channel of DIO - (with edge-triggered interrupt support) - subdevice 3 - last 24 channels of the 48 channel DIO - (no interrupt support for this bank of channels) - - Some notes: - - Synchronous reads and writes are the only things implemented for AI and AO, - even though the hardware itself can do streaming acquisition, etc. Anyone - want to add asynchronous I/O for AI/AO as a feature? Be my guest... - - Asynchronous I/O for the DIO subdevices *is* implemented, however! They are - basically edge-triggered interrupts for any configuration of the first - 24 DIO-lines. - - Also note that this interrupt support is untested. - - A few words about edge-detection IRQ support (commands on DIO): - - * To use edge-detection IRQ support for the DIO subdevice, pass the IRQ - of the board to the comedi_config command. The board IRQ is not jumpered - but rather configured through software, so any IRQ from 1-15 is OK. - - * Due to the genericity of the comedi API, you need to create a special - comedi_command in order to use edge-triggered interrupts for DIO. - - * Use comedi_commands with TRIG_NOW. Your callback will be called each - time an edge is detected on the specified DIO line(s), and the data - values will be two sample_t's, which should be concatenated to form - one 32-bit unsigned int. This value is the mask of channels that had - edges detected from your channel list. Note that the bits positions - in the mask correspond to positions in your chanlist when you - specified the command and *not* channel id's! - - * To set the polarity of the edge-detection interrupts pass a nonzero value - for either CR_RANGE or CR_AREF for edge-up polarity, or a zero - value for both CR_RANGE and CR_AREF if you want edge-down polarity. - -Configuration Options: - [0] - I/O port base address - [1] - IRQ (optional -- for edge-detect interrupt support only, - leave out if you don't need this feature) -*/ + * Driver: pcmmio + * Description: A driver for the PCM-MIO multifunction board + * Devices: (Winsystems) PCM-MIO [pcmmio] + * Author: Calin Culianu <calin@xxxxxxxxx> + * Updated: Wed, May 16 2007 16:21:10 -0500 + * Status: works + * + * A driver for the PCM-MIO multifunction board from Winsystems.
