The following information is for the EMANT300
Turn on and off the LEDs Portwise
Learn:
- Digital Output
- LED
The Digital Port is written portwise ie 8 bits at a time using the USB DAQ Training Kit
WritePort_USB.py
import emant
import time
m = emant.Emant300()
# Windows
m.Open("COM5",dev="300")
# Ubuntu
# m.Open("/dev/ttyUSB0",dev="300")
print m.HwId()
count = 0
while count < 8:
m.WriteDigitalPort(count)
count += 1
time.sleep(1)
m.Close()
Code Explained
m.WriteDigitalPort(count)
The output bits are determined by the count value
8 – 0000 0111 all LEDs are turned off
7 – 0000 0110 only Green LED is turned on
0 – 0000 0000 all LEDs are turned on
m.Open("COM5",dev="300")
For Windows, get serial port using diagnostic.exe
m.Open("/dev/ttyUSB0",dev="300")
For Ubuntu, get serial port using the following
$ dmesg | grep tty
[ 0.000000] console [tty0] enabled
[ 849.395479] usb 2-1: FTDI USB Serial Device converter now attached to ttyUSB0
