Re: AC signal troubleshooting

Ok with the help of the Batch export feature of AnalysIR (Menu->File->Batch Export->IRremote) I ammended some existing code I had to generate your AC power signal from above. I have included an image of the original signal and a newly generated on from an Arduino, below. I will explaing some of the ...

Re: AC signal troubleshooting

Great This is a much cleaner image & and you will notice the large gap in the middle of 19820 uSecs. Unfortunately, IRremote cant handle this. However, we should be able to send you some code to work around this. I will test this out for you tomorrow and post the example code. (its late here now) If...

Re: Connecting to AnalysIR over Serial or LAN

Good news to report! In the upcoming release of AnalysIR, we will be introducing direct connection to the Raspberry PI via LAN (ethernet or Wi-Fi). This will remove the need to use virtual COM ports such as HWVSP - thus making installation much simpler for users. In future, we will also make use of ...

Re: AC signal troubleshooting

Just for completeness/reference, I have attached a trace of the problem signals here, captured using AnalysIR.

Re: AC signal troubleshooting

OK - lets wait for the new IR Receivers. One other thing to try, is to double check that you have the IR Receiver signal pin actually connected to Pin 2 (I have seen situations where an input is connected to an adjacent pin & there was crosstalk onto the correct pin. This is unlikely given the propo...

Re: AC signal troubleshooting

OK We managed to import the Infrared signals into AnalysIR and the screenshot is attached. Some things to note: The signal is like a typical NEC type signal, but with different timings and a different number of bits (looks like 35 bits on first glance) Next there is an issue with your IRremote code ...

AC signal troubleshooting

One backer asked.... I’m trying to decode the IR remote that my AC unit uses, I’ve hat little luck using IRremote or IRlib to record raw IR and play it back, its just not working, but I’ve verified I’m replicating the signal exactly, I suspect maybe its a different frequency than 38kHz… I’m not too ...

Re: Baud rate on UART USB bridge

Hi Yes we have set the BAUD rate quite high to improve the responsiveness of the system, and found no issues with Arduinos when testing. However, you may be in luck - we have recently started testing support for the TI MSP430 LaunchPad which appears to only run at rates up to 115,200. So if you sele...

Re: Constant current IR LED circuit

Sample code used in sketch to generate a circa 37kHz modulated signal @ 50% duty cycle is below: /* Sample modulation signal Turns on an Pin 7 on/off for 13 uSecs, repeatedly. This example code is in the public domain. */ int led = 13; // the setup routine runs once when you press reset: void setup(...
