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 ...

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...

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(...

We recently publish a blog post about a constant current IR LED circuit.

The standard Arduino connection is serial over USB. You will notice from the AnalysIR GUI that we use a baud rate of 2Mbps, which is unusual but works well. (The baud rate is actually ignored for virtual/CDC COM type ports, but is relevant on Arduinos with FTDI-like serial USB) The HW-VSP s/w is use...

We recently receive this question from a backer.... Let me ask you a question about Arduino. Do you connect to the Arduino over Ethernet using the HWVSP software? If so, there must be code in the Arduino that enables Ethernet to serial conversion. You must open a socket connection, and send Ethernet...

One backer reported an issue, whereby AVAST blocked AnalysIR during installation. After checking the AVAST website it appears that this occurs when 'autosandbox' is set to auto. The suggested workaround from AVAST is to set 'autosandbox' to ask . Then the user will be prompted if they want to allow ...

During our phase-1 rollout of AnalysIR, we encountered an issue decoding NEC signals transmitted from IRremote. After lots of head scratching we finally found that one of the definitions in IRremote for NEC is too low. This issue has been reported on the IRremote blog a couple of years ago, but the ...

One user reported that the IR send pin on Leonardo changes from pin 3 for UNO and similar ATMega328 class Arduinos to pin 13 for the Leonardo. I found that the output pin for IRsend for the Leonardo is pin 13 instead of pin 3 (https://github.com/shirriff/Arduino-IRremote/issues/12) We understand tha...

This describes some general issues with Arduino, Leonardo & serial. We recently, came across an issue on one of our Windows PCs with blutetooth installed. We remembered reading previously that the Arduino IDE doesnt react well with serial over bluetooth when it is installed on the same system.Th...
