Python script Optoma UHD40

[devros]

hello, here is my simple script to control on/off my optoma projector UHD40 (RS232)
but should work on other models too... (tested on raspberry with USB serail convertor)

Code: Select all

#!/usr/bin/env python3
import time
import serial
import sys
ser = serial.Serial(
	port='/dev/ttyUSB0',
	baudrate=9600,
	parity=serial.PARITY_NONE,
	stopbits=serial.STOPBITS_ONE,
	bytesize=serial.EIGHTBITS,
	timeout = 1,
	xonxoff = False,
	rtscts = False,
	dsrdtr = False,
	writeTimeout = 2
)
command_off = "~0000 0\r"
command_on = "~0000 1\r"
# command = "~00352 1"

def send_command(command_):
	print ('Connection is %s' % ('open' if ser.isOpen() else 'closed'))
	ser.write(str(command_).encode())
	if ser.isOpen():
		ser.flushInput()
		ser.flushOutput()
		ser.write(str(command_).encode())
		time.sleep(0.1)
		while True:
			line = ser.readline()
			if line:
				print (line.decode('utf-8'))
				break
		ser.close()

try:
  command = sys.argv[1]
except:
  print("no input")
  command = ''

if command == 'ON':
	send_command(command_on)
	print ('Optoma ON')
elif command == 'OFF':
	send_command(command_off)
	print ('Optoma OFF')
else:
	print ('Wrong command')
