MAQUEEN IR Codes

Hi,
I have noticed that the IR codes reported by the sensor do NOT match the NEC IR codes when read in the MIND+ IDE and in MAKECODE IDE.
Reference is only to the last 2 hex digits.
Also in MAKECode, the IR codes read are three digits, but the code executes correctly ONLY if one compares the last two digits.

Below are all three for your study:
Code: Select all
NEC CODES MQ-IR CODES MQ-IR CODES Key Encoded Value in MIND+ in MAKECODE hex dec hex dec dec 0 0xFF4AB5 - 181 B5 - 181 182 1 0xFF6897 - 151 97 - 151 122 2 0xFF9867 - 103 67 - 103 125 3 0xFFB04F - 79 4F - 79 113 4 0xFF30CF - 207 CF - 207 112 5 0xFF18E7 - 231 E7 - 231 124 6 0xFF7A85 - 133 85 - 133 194 7 0xFF10EF - 239 EF - 239 18 8 0xFF38C7 - 199 C7 - 199 128 9 0xFF5AA5 - 165 A5 - 165 190

Please advise where the differences come from.

2019-08-12 18:48:20 The issue is NOT whether the codes work fine or not !

1. Same remote controller used in MakeCode and MIND+ produce different IR codes.
Since the library is by DFROBOT, I am asking why there is a difference.

2. In MakeCode, an IR code for button "1" produces code 122. However, when this code is used in the program IF statement, one must code: "IF message = 22" instead of 122. Why ?

3. In MIND+, IR codes are 3 digits, and the IF statements also use 3 digits. Why the difference from MakeCode?

Below are two programs, one for each IDE. Try it before guaranteeing the codes work OK !

MAKECODE:

Code: Select all

/**
 * Even though the IR message received has the codes 122 and 190 for number 1 and 9 respectively, the IF comparisons have to be for 22 and 90 for it to work!
 * 
 * Checking for 122 and 190 does NOT work.
 */
maqueen.IR_callbackUser(function (message) {
    serial.writeLine("" + message)
    if (message == 22) {
        basic.showString("1")
    }
    if (message == 90) {
        basic.showString("9")
    }
})
serial.redirectToUSB()
serial.writeLine("Port ready")

MIND+:

Code: Select all

/**
 * IR message received has the codes 151 and 165 for number 1 and 9 respectively. The IF comparisons have to be for 151 and 165, NOT LIKE THE MakeCode!
 */
#include <DFRobot_IRremote_dal.h>

DFROBOT_IRremote_Receive remote(16);

void onIRReceive(uint8_t data_IR)
{
	Serial.println(data_IR);
	if ((data_IR == 151)) {
		Serial.println("1");
	}
	if ((data_IR == 165)) {
		Serial.println("9");
	}
}


void setup() {
	Serial.begin(9600);
	Serial.println("PORT Ready");
	remote.begin();
	remote.setCallback(onIRReceive);
}

void loop() {

}
