Re: Control Daikin Air Conditioner using Raspberry pi

Unfortunately, no.

RPi/Linux is not a real time OS...so you need to use tools like LIRC or our modules to send IR, as per my previous post.

FYI: Our A.IR Shield Nano comes with example python code.

Re: Control Daikin Air Conditioner using Raspberry pi

Yes...just use LIRC.

Alternatively, use any of our IR Shields/modules from our shop (with USB and/or WiFi) and connect to them over USB or LAN to send the IR signal.

Re: Help with interesting control problem

un-punched RJ-45 connector shields
..not sure what these are...

Our RepeatIR modules are US$15 each + shipping (US$5.75).


I will send you an email offline...

Re: Help with interesting control problem

If you block any simultaneous signal that arrives while the 1st is active, then that makes it a LOT simpler. EDIT: I would guess that I would have 8 emitters pointing to 8 receivers then "ignore" the receiver side of the circuit. Yes just wrap the receiver & emitter each in a dedicated enclosure (or...

Re: Help with interesting control problem

I was concerned about the IR emitter voltages, as you say, they are less than 3V. Someone mentioned that if I had the emitters "taped" to 8 receivers, then I could parallel the receivers into the processor. Yes, using an IR receiver would address that problem. However, every time a signal goes thru...

Re: Help with interesting control problem

Some points for consideration: - The IR signal at the rack, is not likely a full swing 0->5V (or 3V3)..as its used to drive an IR LED with a swing of ~1.8V. Also, it won't have GND( OR 5V), unless GND can also be provided by the HDMI box. Will probably need some additional electronics to get the sig...

Re: COM port list not visible

Look in device Manager to see if your device is actually connected to a COM port.

Maybe you do not have the correct drivers installed for your Arduino?

Re: Help with interesting control problem

Several possible approaches....depends on how hardware is configured etc. So first post a hardware connection diagram/layout, showing: - how is the IR transferred over HDMI. (Modulated, demodulated, serial data or similar). Does is come out in the rack as IR (or ?) - physical connections to Arduino(...

Re: Difficulty sending Sony 20 bit hex, detected by AnalysIR, sending via Arduino IRRemote library

I had a quick look at the Sony code on IRremote & it looks like it will send & receive SONY signals up to 32 bits long. So perhaps you issue could be related to your IR receiver or IR emitter circuit or code(see below). The 12 bits defined for SONY in the library is to ensure that every SONY signals...

Re: Erratic code capture in AnalysIR

Yes..I saw that...will look at it over the weekend.
