Turn on and off the LEDs Portwise
Learn:
- Digital Output
- LED
The difference between this program and the previous one is that the Digital Port is written portwise ie 8 bits at a time.
WritePort.py
import emant
import time
m = emant.Emant300()
m.Open("00:06:66:00:a1:D8")
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
