Programming DXP channels with Python 3
NOTE
The speed of the data transmission depends on the configured block size and the
set transfer rate. The speed may possibly not be enough for time critical
applications. To achieve faster data processing, the process can be set as a real-time
process.
The following example shows the programming of the digital I/O channels with Python 3.
import sys
#GPIOs-> OUT: IN:
ports = ["88","59"]
# write GPIO:
try:
# set direction to write DXP
fo = open("/sys/class/gpio/gpio" + ports[0] +"/direction", "w")
fo.write("out")
fo.close()
# write GPIO:
f = open("/sys/class/gpio/gpio" + ports[0] +"/value", "w")
f.write("1")
f.close()
except:
# export gpio if not done as yet
f1 = open("/sys/class/gpio/export", "w")
f1.write(ports[0]) f1.close()
# set direction to write DXP
fo = open("/sys/class/gpio/gpio" + ports[0] +"/direction", "w")
fo.write("out")
fo.close()
# write GPIO:
fw = open("/sys/class/gpio/gpio" + ports[0] +"/value", "w")
fw.write("1")
fw.close()
