I downloaded the latest version of IRemote and successfully included the library, It is the latest version too. I am using an elegoo with a ir sensor and a remote. I compile this code in my ide next.
#include <IRremote.h>
int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);
decode_results results;
void setup()
{
Serial.begin(9600);
irrecv.enableIRIn(); // Start the receiver
}
void loop() {
if (irrecv.decode(&results)) {
Serial.println(results.value, HEX);
irrecv.resume(); // Receive the next value
}
delay(100);
}
It is connected to my computer and running properly I see a little red dot blink on the ir receiver when i click a button on the remote but I get the following error.
The function decode(&results)) is deprecated and may not work as expected! Just use decode() - without any parameter.
I don't know any other way to do what I am doing while just using decode(). I cannot see how that's possible. I hope someone has some advice for me thanks alot.
You can either change your code to work with the new version of the library, following the instructions that gfvalvo pointed out or you can delete the new version of the IRremote library from your sketchbook/libraries folder and install an older version (2.x.x) and keep the code the way that it is. The older versions are available for install from the IDE library manager.
Hello. I have gone into the code examples for the latest version and compiled and ran the simple receiver demo. It worked but when I press a button It displays funny characters that I do not recognize like this ⸮⸮[ћN⸮6
