Hi,

My son got a new infrared remote controlled: Winfun R/C Toy Car - ("1155-NL")


[Link: winfun.com]

On the remote control there are three buttons:

1.)
drive forward

2.)
acoustic signal / horn

3.)
drive back and turn right at the same time


In the past I was very interested in IR remote controls related topics and interested in the different IR protocols and I already did read many about them and read many about the different IR related tools:


LIRC -- http://www.lirc.org/
WinLirc -- http://winlirc.sourceforge.net/
IrScrutinizer -- [Link: harctoolbox.org]
Infrared protocol analysis with PC soundcard -- [Link: onetransistor.eu]
SlyControl RCExplorer -- [Link: slydiman.me]
(Infrared) Nethome Protocol Analyzer -- [Link: wiki.nethome.nu]
IR protocol analyzer - [Link: ostan.cz]
[Link: sourceforge.net]
DecodeIR - JP1 Remotes -- [Link: hifi-remote.com]
Interpreting Decoded IR Signals (v2.45) -- [Link: hifi-remote.com]


What I was able to do so far:

I have not got any rs232/usb-hardware for receiving IR signals with my linux PC.
So, accidentally I figured out, that my old HTC Android smartphone has a built-in IR blaster, which can send !AND! receive IR signals.

The next step was to find a possibility to get and capture the IR signals from the toy car IR remote control.
Many IR remote control related Android apps use an internal or external IR code database and do not have a "learn" button for new IR codes.
A few IR remote control related Android apps have the possibility to learn new IR codes.(e.g.: Smart IR Remote - AnyMote)

But I could find only one IR remote control related Android app which can show the newly learned/captured IR remote control signal in detail: "Unified Remote".

But this IR code learning feature is not the main feature of the app.
In the settings: "IR (Select & Learn)" you can test your IR receiver and the app shows a LIRC like RAW IR code.

I could successfully capture the tree IR signals from the IR remote control buttons and I could successfully build a LIRC compatible "remotecontrol.conf" file for importing the signals into IrScrutinizer:



1.)
drive / turn back clockwise:
Unified Remote output:
UIR.FREQ.34090.SEQ.229,150,77,85,77,85,77,151,76,85,77,151,76,151,76,86,76,1591

converted for and used/inserted in IrScrutinizer:
+229 -150 +77 -85 +77 -85 +77 -151 +76 -85 +77 -151 +76 -151 +76 -86 +76 -1591 @ 34090 Hz

IRScrutinizer analysis result:
{34,1k,76,msb}<1,-1|1,-2>(3,-2,A:7,1,-20)+{A=0x16}; Alt leadout form: ^3m

("A=0x16" --> HEX2BIN = 0001 0110)


2.)
drive forward:

Unified Remote output:
UIR.FREQ.35294.SEQ.229,151,76,85,77,85,77,85,77,85,77,151,77,150,77,151,76,1590

converted for and used/inserted in IrScrutinizer:
+229 -151 +76 -85 +77 -85 +77 -85 +77 -85 +77 -151 +77 -150 +77 -151 +76 -1590 @ 35294 Hz

IRScrutinizer analysis result:
{35,3k,76,msb}<1,-1|1,-2>(3,-2,A:7,1,-1588u)+{A=0x07}; Alt leadout form: ^3m

("A=0x07" --> HEX2BIN = 0000 0111)


3.)
acoustic signal / horn:

Unified Remote output:
UIR.FREQ.34413.SEQ.229,149,76,85,77,148,77,85,77,85,77,148,77,85,77,148,77,1599

converted for and used/inserted in IrScrutinizer:
+229 -149 +76 -85 +77 -148 +77 -85 +77 -85 +77 -148 +77 -85 +77 -148 +77 -1599 @ 34413 Hz

IRScrutinizer analysis result:
{34,4k,77,msb}<1,-1|1,-2>(3,-2,A:7,1,-3069u)+{A=0x25}; Alt leadout form: ^5m

("A=0x25" --> HEX2BIN = 0010 0101)

I also could insert the RAW codes into the Android app "RCoid" and could also design and create a simple remote control for controlling the Winfun RC toy car.


Questions:

Referring the three different captured RAW IR data, what kind of IR protocol / IR standard is used?

Does IrScrutinizer analyze and decode the RAW IR signals correctly or are there further possible interpretations?

Referring the three existing / captured IR codes, would it possible to regenerate new IR codes - for example just driving back without turning right at the same time or just driving forward legt/right?


Kind regards

Steven
