mcpwm一次无法中断超过1个引脚的工作怎么解决？

我有点卡在让 mcpwm 捕获在我的 ESP32-WROON 中正常工作...esp-idf v3.3.4 commit cded0f5aa（我知道，老玩具！）。但真的很感谢这方面的任何帮助。

我打算使用 mcpwm 的捕获模式读取 2x 霍尔传感器输出，我设法为其中一个上限输入正确生成中断，但第二个不会触发 isr 处理程序。

我检查了基础知识 - 信号正确到达预期的引脚。

遵循我如何配置我的引脚，遵循mcpwm_basic_config_example.c中的示例

代码：全选

   esp_err_t rv = ESP_OK;

  /* GPIO initialization */
  mcpwm_pin_config_t pin_config;
  pin_config.mcpwm0a_out_num = HBRIDGE_PIN_A;
  pin_config.mcpwm0b_out_num = HBRIDGE_PIN_B;
  pin_config.mcpwm_cap0_in_num = HALL_PIN_0;
  pin_config.mcpwm_cap1_in_num = HALL_PIN_1;
  rv = mcpwm_gpio_init(MCPWM_UNIT_0, MCPWM0A, pin_config.mcpwm0a_out_num);
  rv |= mcpwm_gpio_init(MCPWM_UNIT_0, MCPWM0B, pin_config.mcpwm0b_out_num);
  rv |= mcpwm_gpio_init(MCPWM_UNIT_0, MCPWM_CAP_0, pin_config.mcpwm_cap0_in_num);
  rv |= mcpwm_gpio_init(MCPWM_UNIT_0, MCPWM_CAP_1, pin_config.mcpwm_cap1_in_num);
  if (rv != ESP_OK) {
    SysError(BE_500_TODO, "set pin failed: rv (%d)", rv);
    return false;
  }

  /* Start hall capture */
  rv = mcpwm_capture_enable(MCPWM_UNIT_0, MCPWM_SELECT_CAP0, MCPWM_POS_EDGE, 0);
  rv |= mcpwm_capture_enable(MCPWM_UNIT_0, MCPWM_SELECT_CAP1, MCPWM_POS_EDGE, 0);
  if (rv != ESP_OK) {
    SysError(BE_500_TODO, "capture enable failed: rv (%d)", rv);
    return false;
  }

  MCPWM[MCPWM_UNIT_0]->int_ena.val = (1<<27) | (1<<28);

  /* enable hall isr */
  rv = mcpwm_isr_register(MCPWM_UNIT_0, hall_isr, NULL, ESP_INTR_FLAG_IRAM, NULL);
  if (rv != ESP_OK) {
    SysError(BE_500_TODO, "isr register failed: rv (%d)", rv);
    return false;
  }

  /* PWM configuration */
  mcpwm_config_t pwm_config;
  pwm_config.frequency = 20000;
  pwm_config.cmpr_a = 0.0;
  pwm_config.cmpr_b = 0.0;
  pwm_config.counter_mode = MCPWM_UP_COUNTER;
  pwm_config.duty_mode = MCPWM_DUTY_MODE_0;
  rv = mcpwm_init(MCPWM_UNIT_0, MCPWM_TIMER_0, &pwm_config);
  if (rv != ESP_OK) {
    SysError(BE_500_TODO, "init failed: rv(%d)", rv);
    return false;
  }

我还生成PWM输出，它正在示波器上正常测量。只有应该发生的 CAP1 事件永远不会触发！
