Can this lib be used to control an irDroid-Usb-Transmitter? #1084

|
im using an esp32-s3-otg-usb board with this device connected as a cdc -usb serial device connected to my boards usb-host type A connector. i can connect and open the ir device, but dont know how use it. so wondering can i somehow adapt your lib to control it? i'm trying to avoid rewriting Lirc code. from: https://irdroid.com/usb-infrared-transmitter/ The Irdroid USB Infrared transmitter provides infrared interface for your PC and your Android Device. It allows you to control and automate all your home infrared appliances via PC and Android. The USB Infrared transmitter is compatible with Linux, Windows and *Android. The unit features IR transmitter that emmits infrared signals with wavelenght of 940nm @38khz , which is the Standard IR frequency for most of the IR controlled home appliances on the market. The unit has 3 powerful infrared LEDS which triples the operating range and enlarges the IR LED viewing angle to about 180 degrees. The USB Infrared transmitter’s powerful infrared LEDs, provide a operating range of more than 10 meters line of sight, which makes it useful for automating large rooms , halls etc. The unit is open source and open hardware licensed under GNU GPL 2.0 and it comes with source code, schematics and production files. The USB Infrared transmitter is compatible with Winlirc , via the IRToy driver for WinLirc, and in Linux you can use it via the IRman LIRC driver. The unit is based on the PIC 18f2550 microcontroller, working at 20MHz. The Default IRman Driver for Lirc does not allow transmit by default, below is a modified downloadable version, which works with LIRC. If you use the USB Infrared Transmitter in Windows, then you need to download the .inf driver below . The Driver will allow you to use the USB Transmitter with WinLirc. Technical Specifications: Interface – USB (CDC ACM Device) |

What exactly do you need to control an irDroid-Usb-Transmitter??? USB protocol? USB driver? |

Hi Armin,
I'm trying to take an esp32-s3-otg-usb board together with an irDroidIr
cdc/acm usb dongle to emulate an IR remote to control my home IR controlled
devices. I'm using the esp32-arduino library with the arduino IDE to
program the board.
https://espressif-docs.readthedocs-hosted.com/projects/espressif-esp-dev-kits/en/latest/esp32s3/esp32-s3-usb-otg/user_guide.html
ESP32-S3-USB-OTG is a development board that focuses on USB-OTG function
verification and application development. It is based on ESP32-S3 SoC,
supports Wi-Fi and BLE 5.0 wireless functions, and supports USB host and
USB device functions. It can be used to develop applications such as
wireless storage devices, Wi-Fi network cards, LTE MiFi, multimedia
devices, virtual keyboards and mice. The development board has the
following features:
Onboard ESP32-S3-MINI-1-N8 module, with built-in 8 MB flash
Onboard USB Type-A host and device interface, with built-in USB interface
switching circuit
Onboard USB to serial debugging chip (Micro USB interface)
Onboard 1.3-inch LCD color screen, supports GUI
Onboard SD card interface, compatible with SDIO and SPI interfaces
Onboard charging IC, can be connected to lithium battery

I'm pretty novice dealing with Ir, but i've made pretty good progress. I
got the dongle working on my Win10 laptop using WinLirc to turn my Vizio tv
on/off. I used an usb snooper/monitor to capture the raw codes sent from
Winlirc to the dongle:
Decimal uint8 array used to toggle tv power:
[1,164,0,206,0,26,0,23,0,26,0,23,0,26,0,74,0,26,0,23,0,26,0,23,0,26,0,23,0,26,0,23,0,26,0,23,0,26,0,74,0,26,0,74,0,26,0,23,0,26,0,74,0,26,0,74,0,26,0,74,0,26,0,74,0,26,0,74,0,26,0,23,0,26,0,23,0,26,0,23,0,26,0,74,0,26,0,23,0,26,0,23,0,26,0,23,0,26,0,23,0,26,0,74,0,26,0,74,0,26,0,74,0,26,0,23,0,26,0,74,0,26,0,74,0,26,0,74,0,26,0,74,0,26,7,102,1,165,0,102,0,26,17,122,1,165,0,102,0,26,17,122,1,165,0,102,0,26]
I was able to get the usb host type A interface on the esp32 board to
emulate a cdc/acm usb host using tinyUsb. It recognizes and communicates
with the ir dongle.
The tinyUsb code abstracts the complexity of the usb acm/cdc host down to a
read from dongle and write to dongle functions.
when i write the above decimal array to the dongle, it actually turns on
and off my Vizio TV! 😎
My knowledge of lirc comes only from reading its code and using it with
winlirc. This is only my best guess... but I think of lirc as a way to take
a lirc formatted remote config file and parse it into a raw array of pulse
codes used to control an ir device. i.e.
*Use this lirc config file:*

From looking at your project it seems it does more or less the same. So I'm
hoping i can somehow adapt your code to create an arduino sketch that takes
as input remote device (i.e. Vizio) and device key (KEY_POWER) to produce
the raw pulse codes needed to control the ir device.

This library is much to basic and targeted to small CPU and memory resources and therefore not able to interprete LIRC data. |

No, it cannot. This library (together with suitable hardware (IR LEDs, TSOP receiver)) does approximately the same as the IrDroid (which is a simplified version of the sold-out IrToy.) See that link for a serial API for the IrToy/IRDroid. How to use that thing is OT here. Best way to use Lirc file is to use IrScrutinizer to convert it to something your preferred IR library can use. (Presently, the IRRemote export has not been updated for geneating code for version 4 yet (bengtmartensson/IrScrutinizer#444), but I hope to do that next week.) |

Thanks! It initially looks like a really comprehensive ir format transform tool that could work for me. i.e. input a lirc formatted file for the desired remote from the lirc sourceforge site. Then export a toyIr file with the raw pulse codes that i can use to send (xmit) via the irDroid Ir transmitter to control the ir device. It's probably the name irScutinizer that threw me off in my searches, because i assumed it only analyzed raw recorded ir input (which i'm not interested in doing), and never scrutinized its purpose. (pun intended 😜) thanks again... I'll post any further comments to irScrutinizer! 🤓👍 |
