ESP32串口监视器异常：TMC2209驱动通信测试无输出

我是新手，正在尝试将ESP32模块与TMC2209驱动连接，使用janelia-arduino的TMC2209库进行测试。运行库中的波特率测试示例后，VSCode的PlatformIO串口监视器中看不到任何输出。以下是我的PlatformIO配置、测试代码，以及串口监视器截图：

PlatformIO配置 #

[env:nodemcu-32s]
platform = espressif32
board = nodemcu-32s
framework = arduino
lib_deps = janelia-arduino/TMC2209@^9.0.6
monitor_speed = 115200

测试代码 #

#include <Arduino.h>
#include <TMC2209.h>

// 本示例不适用于无硬件串口的Arduino板，比如Uno、Nano和Mini。
// 更多细节参考：
// https://www.arduino.cc/reference/en/language/functions/communication/serial/

  }

  bool test_further = false;

  Serial.print("serial1_baud_rate = ");
  Serial.println(serial1_baud_rate);

  }

    for (uint8_t i=0; i<SUCCESSIVE_OPERATION_COUNT; ++i)
    {
      microstep_sum += stepper_driver.getMicrostepsPerStep();
    }
    if (microstep_sum > 0)
    {
      Serial.println("连续读取测试通过！");
    }
    else
    {
      Serial.println("连续读取测试失败！");
    }
    uint8_t itc_begin = stepper_driver.getInterfaceTransmissionCounter();
    for (uint8_t i=0; i<SUCCESSIVE_OPERATION_COUNT; ++i)
    {
      stepper_driver.disable();
    }
    uint8_t itc_end = stepper_driver.getInterfaceTransmissionCounter();
    if (itc_begin != itc_end)
