irMagician can handle only one IR signal in itself. You need to download, if you use other IR signal data in every times. This page shows basic use case for IR signal uploading(save) and downloading(load).

1. Capture IR signal
2. Confirm correct captured IR signal data with play command
3. Save captured IR signal data
4. Load & Play captured IR signal data

Using python for independent platform. irMagician is based on CDC-ACM. Pyserial is mandatory. This sample does not care error handling. It will be required to make real application.

1. Capture IR signal
   For capturing IR signal, script as below,
   Capture - IR remote signal

   Python

   # -*- coding: utf-8 -*- import sys import serial import time import json ser = serial.Serial("/dev/ttyACM0", 9600, timeout = 1) ser.write("c\r\n") time.sleep(1.0) print ser.readline() ser.close()

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

   # -*- coding: utf-8 -*-   import sys import serial import time import json     ser = serial.Serial("/dev/ttyACM0", 9600, timeout = 1)   ser.write("c\r\n") time.sleep(1.0) print ser.readline()   ser.close()

2. Confirm correct captured IR signal data with play command
   Evaluate captured IR signal data to point to target device. Just changed to command as “c’ to ‘p’.
   Play - IR remote signal playback

   Python

   # -*- coding: utf-8 -*- import sys import serial import time import json ser = serial.Serial("/dev/ttyACM0", 9600, timeout = 1) ser.write("p\r\n") time.sleep(1.0) print ser.readline() ser.close()

   1 2 3 4 5 6 7 8 9 10 11 12 13 14

   # -*- coding: utf-8 -*-   import sys import serial import time import json   ser = serial.Serial("/dev/ttyACM0", 9600, timeout = 1)   ser.write("p\r\n") time.sleep(1.0) print ser.readline()   ser.close()

3. Save captured IR signal data
   Captured IR signal data is stored to json format. This point of view, inquiry for number of data, bank handling
   Save IR signal - inquiry data point and saving format as JSON

   Python

   # -*- coding: utf-8 -*- import sys import serial import time import json rawX = [] ser = serial.Serial("/dev/ttyACM0", 9600, timeout = 1) #ser = serial.Serial("/dev/tty.usb0121", 9600, timeout = 1) ser.readline() argvs = sys.argv argc = len(argvs) if (argc != 2): print 'Usage: # python %s filename' % argvs[0] quit() print argvs[1] f = open(argvs[1], 'w') ser.write("I,1\r\n") time.sleep(1.0) recNumberStr = ser.readline() recNumber = int(recNumberStr, 16) ser.write("I,6\r\n") time.sleep(1.0) postScaleStr = ser.readline() postScale = int(postScaleStr, 10) #for n in range(640): for n in range(recNumber): bank = n / 64 pos = n % 64 if (pos == 0): ser.write("b,%d\r\n" % bank) ser.write("d,%d\n\r" % pos) xStr = ser.read(3) xData = int(xStr, 16) rawX.append(xData) json_data = {'format':'raw', 'freq':38, 'data':rawX, 'postscale':postScale} json.dump(json_data, f) f.close() ser.close()

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

   # -*- coding: utf-8 -*-   import sys import serial import time import json   rawX = []   ser = serial.Serial("/dev/ttyACM0", 9600, timeout = 1) #ser = serial.Serial("/dev/tty.usb0121", 9600, timeout = 1) ser.readline()   argvs = sys.argv argc = len(argvs) if (argc != 2): print 'Usage: # python %s filename' % argvs[0] quit() print argvs[1] f = open(argvs[1], 'w')     ser.write("I,1\r\n") time.sleep(1.0) recNumberStr = ser.readline() recNumber = int(recNumberStr, 16)   ser.write("I,6\r\n") time.sleep(1.0) postScaleStr = ser.readline() postScale = int(postScaleStr, 10)     #for n in range(640): for n in range(recNumber):     bank = n / 64     pos = n % 64     if (pos == 0):         ser.write("b,%d\r\n" % bank)       ser.write("d,%d\n\r" % pos)     xStr = ser.read(3)     xData = int(xStr, 16)     rawX.append(xData)   json_data = {'format':'raw', 'freq':38, 'data':rawX, 'postscale':postScale} json.dump(json_data, f)   f.close()   ser.close()

4. Load & Play captured IR signal data
   Download IR signal data from json file then send it to target device
   Load & Play - load with Jason format, then play

   Python

   # -*- coding: utf-8 -*- import sys import serial import time import json ser = serial.Serial("/dev/ttyACM0", 9600, timeout = 1) #ser = serial.Serial("/dev/tty.usb0121", 9600, timeout = 1) ser.readline() argvs = sys.argv argc = len(argvs) if (argc != 2): print 'Usage: # python %s filename' % argvs[0] quit() f = open(argvs[1]) json_data = json.load(f) f.close() recNumber = len(json_data['data']) rawX = json_data['data'] ser.write("n,%d\r\n" % recNumber) ser.readline() postScale = json_data['postscale'] ser.write("k,%d\r\n" % postScale) #time.sleep(1.0) ser.readline() for n in range(recNumber): bank = n / 64 pos = n % 64 if (pos == 0): ser.write("b,%d\r\n" % bank) ser.write("w,%d,%d\n\r" % (pos, rawX[n])) ser.write("p\r\n") ser.readline() ser.close()

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45

   # -*- coding: utf-8 -*-   import sys import serial import time import json   ser = serial.Serial("/dev/ttyACM0", 9600, timeout = 1) #ser = serial.Serial("/dev/tty.usb0121", 9600, timeout = 1) ser.readline()   argvs = sys.argv argc = len(argvs) if (argc != 2): print 'Usage: # python %s filename' % argvs[0] quit() f = open(argvs[1])   json_data = json.load(f) f.close()   recNumber = len(json_data['data']) rawX = json_data['data']     ser.write("n,%d\r\n" % recNumber) ser.readline()   postScale = json_data['postscale'] ser.write("k,%d\r\n" % postScale) #time.sleep(1.0) ser.readline()   for n in range(recNumber):     bank = n / 64     pos = n % 64     if (pos == 0):      ser.write("b,%d\r\n" % bank)       ser.write("w,%d,%d\n\r" % (pos, rawX[n]))   ser.write("p\r\n") ser.readline()   ser.close()
