Trouble about control Servos on Matrix creator.!

I use Matrix Creator to control 2 servos, but only one active and the other does not move. I try to create 2 objects on matrix_hal :: MatrixIOBus is bus1, bus2 created 2 of them. I do not know if the matrix can control a servo or not. you help, thank you very much!
The code below is just a test, I just created an object on matrix_hal :: MatrixIOBus.thank you very much!

#include <iostream>
#include "matrix_hal / gpio_control.h"
#include "matrix_hal / matrixio_bus.h"

float angle, angle1;

int main ()
{
  matrix_hal :: MatrixIOBus bus;
  if (! bus.Init ()) return false;
  // if (! bus.Init ()) std :: cout << "error SerR" << std :: endl;
  
  matrix_hal :: GPIOControl SerR, SerV;
  SerR.Setup (& bus);
  SerV.Setup (& bus);
while (1)
{
  std :: cout << "Chose angle:" << std :: endl;
  std :: cin >> angle;
  std :: cin >> angle1;
  SerR.SetMode (0,1);
  SerR.SetFunction (0,1);
  SerV.SetMode (2.1);
  SerV.SetFunction (2,1);
  SerR.SetServoAngle (angle, 1., 0);
  SerV.SetServoAngle (angle1,1., 2);
}
  return 0;
}

I think the issue is related to that you just need one instance of GPIOControl, to select different Servos you use the pin parameter for it.
Here is the code with some changes, its hust a guide, I didnt build it .

Let me know how it goes.

#include <iostream>
#include "matrix_hal / gpio_control.h"
#include "matrix_hal / matrixio_bus.h"

#define SERVO_0_PIN = 0
#define SERVO_1_PIN = 1

#define GPIO_INPUT_MODE = 0
#define GPIO_OUTPUT_MODE = 1

#define GPIO_BANK_0 = 0 // From pin  0 - 3
#define GPIO_BANK_1 = 1 // From pin  4 - 7
#define GPIO_BANK_2 = 2 // From pin  8 - 11
#define GPIO_BANK_3 = 3 // From pin 12 - 15

#define GPIO_FUNCTION = 0 // General GPIO I/O
#define PWM_FUNCTION = 1 // PWM I/O

float angle_0, angle_1;

int main ()
{
  matrix_hal :: MatrixIOBus bus;
  if (! bus.Init ()) {
    std :: cout << "Error!" << std :: endl;
    return false;
  } 
  
  matrix_hal :: GPIOControl gpio_ctrl;
  gpio_ctrl.Setup(& bus);
  
  gpio_ctrl.SetMode(SERVO_0_PIN, GPIO_OUTPUT_MODE);
  gpio_ctrl.SetMode(SERVO_1_PIN, GPIO_OUTPUT_MODE);
  gpio_ctrl.SetFunction(SERVO_0_PIN, PWM_FUNCTION);
  gpio_ctrl.SetFunction(SERVO_1_PIN, PWM_FUNCTION);
  
  while (1) {
    
    std :: cout << "Chose angle:" << std :: endl;
    std :: cin >> angle_0; // in degrees
    std :: cin >> angle_1; // in degrees

    gpio_ctrl.Set9GServoAngle(angle_0, SERVO_0_PIN);
    gpio_ctrl.Set9GServoAngle(angle_1, SERVO_1_PIN);

    // For non standart servo look for the min pulse 
    // in the datasheet and use it in the 
    // 2nd parameter in SetServoAngle():
    
    // int min_pulse_ms = ???
    // gpio_ctrl.SetServoAngle(angle_0, min_pulse_ms, SERVO_0_PIN);
    // gpio_ctrl.SetServoAngle(angle_1, min_pulse_ms, SERVO_1_PIN);

  }

  return 0;

thx you,it’ worked.!
thank you, it worked. I created 2 objects of 2 servo pins so it did not work. happy one day, thank you so much!
