求助，GD32470V_START UART无法正常运行
GD32470V_START（GD32F470VKT6）UART无法正常运行，逻辑分析仪测试针脚无变化（一直高电平）。所有函数都使用GD32470V_START_Demo_Suites的例子。感谢所有提供帮助的同学。gd_eval_com_init来自官方教程.intmain(void){/*configuresystick*/systick_config();/*configureEVAL_COM0*/gd_eval_com_init(EVAL_COM0);/*enabletheLEDsGPIOclock*/rcu_periph_clock_enable(RCU_GPIOC);/*configureLED2GPIOport*/gpio_mode_set(GPIOC,GPIO_MODE_OUTPUT,GPIO_PUPD_NONE,GPIO_PIN_6);gpio_output_options_set(GPIOC,GPIO_OTYPE_PP,GPIO_OSPEED_50MHZ,GPIO_PIN_6);while(1){usart_data_transmit(EVAL_COM0,'O');while(RESET==usart_flag_get(EVAL_COM0,USART_FLAG_TBE));usart_data_transmit(EVAL_COM0,'K');while(RESET==usart_flag_get(EVAL_COM0,USART_FLAG_TBE));/*waitforcompletionofUSARTtransmission*/while(RESET==usart_flag_get(EVAL_COM0,USART_FLAG_TC)){}/*turnonLED2*/gpio_bit_set(GPIOC,GPIO_PIN_6);//gpio_bit_set(GPIOA,GPIO_PIN_9);delay_1ms(100);gpio_bit_reset(GPIOC,GPIO_PIN_6);//gpio_bit_reset(GPIOA,GPIO_PIN_9);delay_1ms(100);}}
