想知道是否有人可以帮我解决这个问题。这是我的示例代码。我已尽可能简单地将其分解以消除潜在原因：
- #include
- #include "freertos/FreeRTOS.h"
- #include "freertos/task.h"
- #include "freertos/queue.h"
- #include "driver/gpio.h"
- #include “esp_log.h”
- #include “iot_button.h”
- #include “esp_timer.h”
- #include "bdc_motor.h"
- #include <字符串.h>
- #define BDC_MCPWM_TIMER_RESOLUTION_HZ 10000000 // 10MHz, 1 tick = 0.1us
- #define BDC_MCPWM_FREQ_HZ 25000 // 25KHz PWM
- #define BDC_MCPWM_DUTY_TICK_MAX (BDC_MCPWM_TIMER_RESOLUTION_HZ / BDC_MCPWM_FREQ_HZ) // 我们可以为占空比设置的最大值，单位为滴答
- #define BDC_MCPWM_GPIO_A 12 // 转发
- #define BDC_MCPWM_GPIO_B 16 // 向后
- #define 电机速度 200
- static const char * TAG = "例子" ;
- void app_main (无效)
- {
- ESP_LOGI ( TAG , "创建直流电机" ) ;
- bdc_motor_config_t motor_config = {
- . pwm_freq_hz = BDC_MCPWM_FREQ_HZ ,
- . pwma_gpio_num = BDC_MCPWM_GPIO_A ,
- . pwmb_gpio_num = BDC_MCPWM_GPIO_B ,
- } ;
- bdc_motor_mcpwm_config_t mcpwm_config = {
- . group_id = 0 ,
- . resolution_hz = BDC_MCPWM_TIMER_RESOLUTION_HZ ,
- } ;
- bdc_motor_handle_t motor = NULL ;
- ESP_ERROR_CHECK ( bdc_motor_new_mcpwm_device ( & motor_config , & mcpwm_config , & motor ) ) ;
- ESP_LOGI ( TAG , "启动电机" ) ;
- ESP_ERROR_CHECK ( bdc_motor_enable ( motor ) ) ;
- bdc_motor_set_speed （电机电机速度）； // 最多 400
- 而( 1 ) {
- ESP_ERROR_CHECK （ bdc_motor_forward （电机））；
- vTaskDelay ( 5000 / portTICK_PERIOD_MS ) ;
- ESP_ERROR_CHECK ( bdc_motor_reverse ( motor ) ) ;
- vTaskDelay ( 5000 / portTICK_PERIOD_MS ) ;
- }
- }
一旦我启用 PSRAM，我得到这个输出：
