Hello, I am desperate for an answer
im trying to send a command to the Arduino to turn a servo motor. I enter the command in CAN MONITOR, the motor turns, but when I send the command through a virtual button, nothing happens. I am uploading my codes please help me with this thing
Simple command as 0x0c80:0x0 0x32

my ino code

#include <Wire.h>
#include <Adafruit_PWMServoDriver.h>

Adafruit_PWMServoDriver pwm = Adafruit_PWMServoDriver();

#define SERVOMIN  125
#define SERVOMAX  625

void setup() {
  Serial.begin(9600);
  pwm.begin();
  pwm.setPWMFreq(60);
}

void loop() {
  if (Serial.available() >= 12) {  // 4 bytes for serialBlockTag, 4 bytes for canFrameId, 8 bytes for frameData
    byte serialBlockTag[4];
    Serial.readBytes(serialBlockTag, 4);

    if (serialBlockTag[0] == 0x44 && serialBlockTag[1] == 0x33 && serialBlockTag[2] == 0x22 && serialBlockTag[3] == 0x11) {
      unsigned long canFrameId;
      Serial.readBytes((char*)&canFrameId, 4);

      if (canFrameId == 0x0c80) {
        byte frameData[8];
        Serial.readBytes(frameData, 8);

        int combinedValue = (frameData[0] << 8) | frameData[1]; 
        int servoNum = (combinedValue >> 8) & 0xFF;
        int angle = combinedValue & 0xFF;

        if (servoNum >= 0 && servoNum < 16 && angle >= 0 && angle <= 180) {
          int pulseLength = map(angle, 0, 180, SERVOMIN, SERVOMAX);
          pwm.setPWM(servoNum, 0, pulseLength);
          Serial.print("Servo ");
          Serial.print(servoNum);
          Serial.print(" angle: ");
          Serial.println(angle);
        } else {
          Serial.println("Invalid servo number or angle.");
        }
      } else {
        Serial.println("Invalid CAN frame ID.");
      }
    } else {
      Serial.println("Invalid serial block tag.");
    }
  }
}

Wow what an answer I don't know with this AI or user anyway you helped me a lot I can send commands now only I have delay problems thanks a lot
