Updated: 13 May 2012
|
||||
Status: Stable
|
||||
Configuration options:
|
||||
You have to upload firmware with the -i option. The
|
||||
firmware is usually installed under /usr/share/usb or
|
||||
/usr/local/share/usb or /lib/firmware.
|
||||
|
||||
Connection scheme for the counter at the digital port:
|
||||
0=/CLK0, 1=UP/DOWN0, 2=RESET0, 4=/CLK1, 5=UP/DOWN1, 6=RESET1.
|
||||
The sampling rate of the counter is approximately 500Hz.
|
||||
The following subdevices are available
|
||||
- Analog input
|
||||
subdevice: 0
|
||||
number of channels: 8
|
||||
max data value: 4095
|
||||
ranges:
|
||||
all channels:
|
||||
range = 0 : [-4.096 V,4.096 V]
|
||||
range = 1 : [-2.048 V,2.048 V]
|
||||
range = 2 : [0 V,4.096 V]
|
||||
range = 3 : [0 V,2.048 V]
|
||||
command:
|
||||
start: now|int
|
||||
scan_begin: timer (contains the sampling interval. min is 125us / chan)
|
||||
convert: now
|
||||
scan_end: count
|
||||
stop: none|count
|
||||
- Analogue output:
|
||||
subdevice: 1
|
||||
number of channels: 4
|
||||
max data value: 4095
|
||||
ranges:
|
||||
all channels:
|
||||
range = 0 : [-4.096 V,4.096 V]
|
||||
range = 1 : [0 V,4.096 V]
|
||||
command:
|
||||
start: now|int
|
||||
scan_begin: timer (contains the sampling interval. min is 1ms.)
|
||||
convert: now
|
||||
scan_end: count
|

stop: none|count
|
||||
- Digital I/O
|
||||
subdevice: 2
|
||||
number of channels: 8
|
||||
- Counter
|
||||
subdevice: 3
|
||||
number of channels: 4
|
||||
max data value: 65535
|
||||
Pin assignments on the D-connector:
|
||||
0=/CLK0, 1=UP/DOWN0, 2=RESET0, 4=/CLK1, 5=UP/DOWN1, 6=RESET1
|
||||
- PWM
|
||||
subdevice: 4
|
||||
number of channels: 8 or 4 + polarity output for H-bridge
|
||||
(see INSN_CONFIG_PWM_SET_H_BRIDGE where
|
||||
the first byte is the value and the
|
||||
second the polarity)
|
||||
max data value: 512
|
||||
|
||||
Please note that under USB2.0 the length of the channel list determines
|
||||
the max sampling rate. If you sample only one channel you get 8kHz
|
||||
sampling rate. If you sample two channels you get 4kHz and so on.
|
||||
Configuration options
|
||||
The device requires firmware which is usually
|
||||
uploaded automatically by udev/hotplug at the moment
|
||||
the driver module is loaded.
|
||||
In case udev/hotplug is not enabled you need to upload
|
||||
the firmware with comedi_config -i usbdux_firmware.bin.
|
||||
The firmware is usually installed under /lib/firmware
|
||||
or can be downloaded form http://www.linux-usb-daq.co.uk.
