Mr. Aron het Lam, I really need your advice

[xx1ong]

Hello, Mr. Aron het Lam, I like your work very much, which has given me a very good experience in many application scenarios. Since I usually use the vmix coaching software, now I found a piece of code that allows me to use the same on esp8266, because I designed the LED bulb pin according to your code and the pin of vmix code is different. As a result, the colors are different. PVW is now green and PGM is blue. As my skill is very limited, I cannot solve this problem. I hope you can guide me to modify it so that this vmix code can also use your pin scheme. Thank you very much. VMIX code link:

Im not entirely Shure what the issue is, but assuming you have it working other than PGM being blue instead of red, the following should fix it.

My pin setup is: D0 RED D1 BLUE D2 GREEN

So if you put in these lines in the beginning of the code you posted I think it should work:

int redLED = D0;
int yellowLED = 4;
int blueLED = D1;
int greenLED = D2;

[xx1ong]

Mr. Aron het Lam, thanks for your busy reply, I will experiment and reply you again to confirm whether it can run, because many people still have the habit of using vmix, I also hope that Mr. Aron het Lam has considered developing the vmix tally code

[xx1ong]

I'll take the original code int redLED = 5; //D1 or GPIO 5 int yellowLED = 4;//D2 or GPIO 4 int blueLED = 0; //D3 GPIO0 int greenLED = 2;//D4 or GPIO to indicate power

To modify into

int redLED = D0; int yellowLED = 4; int blueLED = D1; int greenLED = D2;

It doesn't work properly, but thank you very much for your reply. I will continue the experiment

[AronHetLam]

Looking a bit more at the code you posted, something seems off here:

if (currentHTML.substring(13, 20) == colorGreen)
          {
            digitalWrite(redLED, HIGH);
            digitalWrite(yellowLED, LOW);
             digitalWrite(blueLED, LOW);
            Serial.println("it is green" );
          }

          if (currentHTML.substring(13, 20) == colorYellow)
          {
            Serial.println("it is yellow" );
            digitalWrite(redLED, LOW);
            digitalWrite(yellowLED, HIGH);
            Serial.println("it is YELLOW" );
             digitalWrite(blueLED, LOW);

          }

          if (currentHTML.substring(13, 20) == colorBlue)
          {
            Serial.println("it is blue" );
            digitalWrite(redLED, LOW);
            digitalWrite(yellowLED, LOW);
            digitalWrite(blueLED, HIGH);

          }

When you print green you set redLED high, and there is no code to make it green.

[AronHetLam]

Also possibly D2 could be the same as just 4, which could make green and yellow conflict in the code I sent you earlier. Make sure yellow and green are different pins

[xx1ong]

也可能 D2 与 4 相同，这可能会导致我之前发送给您的代码中的绿色和黄色冲突。确保黄色和绿色是不同的引脚

I will try to remove the yellow LED code, as it is enough to keep the PVW green and PGM red. Thank you

[xx1ong]

也可能D2与4相同，这可能会导致我之前发给您的代码中的绿色和黄色冲突。确保黄色和绿色是不同的引脚

我将尝试删除黄色 LED 代码，因为它足以保持 PVW 绿色和 PGM 红色。谢谢

Or I have another idea. Could you please change your code pin and VMIX code pin to be the same, so that they can work together in a compatible way?

[xx1ong]

可能D2与4相同，这可能会导致我之前发给您的代号中的绿色和黄色冲突。确保黄色和绿色是不同的引脚

我将尝试去除黄色 LED 代码，因为它足以保持 PVW 绿色和 PGM 红色。谢谢

或者我有别的想法。您能否将您的代码 pin 和 VMIX 代码 pin 更改为相同，以便它们可以以兼容的方式一起工作？

In today's test, I found that red is connected to D2 pin, blue is connected to D1 pin, green is not soldered, VMIX code can work normally

[AronHetLam]

In today's test, I found that red is connected to D2 pin, blue is connected to D1 pin, green is not soldered, VMIX code can work normally

I'm a little confused at this point. Did you get it to work with the Vmix code? Do you have the LED connected as my code requires it?

Else I see that the Vmix code uses yellowLED for PVW and redLED for PGM In that case the following should work, assuming you soldered you'r LED like my code requires it.

int redLED = D0;
int yellowLED = D2; // Actually connected to green pin
int blueLED = D1;
int greenLED = D4; // You probably haven't connected this. Vmix code uses this to show it's on.

[xx1ong]

今天测试发现红色接D2脚，蓝色接D1脚，绿色没有焊，VMIX代码可以正常工作

在这一点上我有点困惑。你让它与 Vmix 代码一起工作了吗？ 您是否按照我的代码要求连接了 LED？

否则，我看到 Vmix 代码使用 yellowLED 表示 PVW，使用 redLED 表示 PGM 在这种情况下，以下应该有效，假设您按照我的代码要求焊接了 LED。

int redLED = D0;
int yellowLED = D2; // Actually connected to green pin
int blueLED = D1;
int greenLED = D4; // You probably haven't connected this. Vmix code uses this to show it's on.

Hello, I mean by flashing in a different code, then no need to change the pin relationship.

[AronHetLam]

Yes, I understand, but how is your LED connected to the ESP8266?

[xx1ong]

是的，我明明白了，但是你的LED是如何连接到ESP8266的？

red=D0、GROUNE=G、GRWWN=D2、BLUE=D1

[xx1ong]

是的，我明明白了，但是你的LED是如何连接到ESP8266的？

红色=D0、GROUNE=G、GRWWN=D2、蓝色=D1

Wire the ATEM 8266 according to your design

[AronHetLam]

是的，我明明白了，但是你的LED是如何连接到ESP8266的？

red=D0、GROUNE=G、GRWWN=D2、BLUE=D1

In that case this should work, as the Vmix code uses yellowLED for PVW

int redLED = D0;
int yellowLED = D2; // Actually connected to green pin
int blueLED = D1;
int greenLED = D4; // You probably haven't connected 

If it doesn't can you check what color your LED is when it prints it is green in the serial console? The LED should be red

And when it prints it is yellow the LED should be green

Some people have also had wierd issues like this if they selected the incorrect board in the board manager. Which board did you select?

[xx1ong]

Hello, sorry, I was just busy yesterday, and I chose D1 R2 & MINI. I am constantly experimenting, but I haven't got the result yet. Thank you very much for your patient and professional reply. I will continue to study.

[xx1ong]

Thank you very much Mr. Aron het Lam. Through your code, I have successfully flashed different codes to make ATEM and VMIX compatible, thank you again. I wish you a happy life and happy every day.

[AronHetLam]

You're welcome. Those look nice too 😊
