GD32E230系列的，里面描述的单周期乘法器和17周期分频器我要怎么去使用它?在哪里有详细的描述？

GD32E230的datasheet中可以看到PA2和PA3是可以复用到USART1的，然后使用官方的例程，将官方例程默认引进从串口0中的PA9、PA10可以打印。请教一下有没有人知道PA2、PA3怎么当串口1使用？以下是官方例程，我将引脚宏定义改成PA2和PA3,串口0也改为了串口1：usart.h文件#definePrint_GPIO_RCURCU_GPIOA//串口对应GPIO端口的时钟#definePrint_USART_RCURCU_USART1//对应串口号的时钟#definePrint_GPIOGPIOA//串口对应GPIO端口#definePrint_GPIO_AFGPIO_AF_1//串口是GPIO引脚的复用功能1（查询芯片数据手册）#definePrint_TX_PINGPIO_PIN_2//串口对应的GPIO引脚#definePrint_RX_PINGPIO_PIN_3//串口对应的GPIO引脚#definePrint_USARTUSART1//print所使用的串口1usart.c文件//串口打印初始化voidusart_print_init(void){usart_print_gpio_init();usart_print_config();}/*!\briefinitilizethecomGPIO\paramnone\param[out]none\retvalnone*/voidusart_print_gpio_init(void){/*enablePrintGPIOclock*/rcu_periph_clock_enable(Print_GPIO_RCU);/*connectporttoUSARTx_Tx*/gpio_af_set(Print_GPIO,Print_GPIO_AF,Print_TX_PIN);/*connectporttoUSARTx_Rx*/gpio_af_set(Print_GPIO,Print_GPIO_AF,Print_RX_PIN);/*configureUSARTTxasalternatefunctionpush-pull*/gpio_mode_set(Print_GPIO,GPIO_MODE_AF,GPIO_PUPD_PULLUP,Print_TX_PIN);gpio_mode_set(Print_GPIO,GPIO_MODE_AF,GPIO_PUPD_PULLUP,Print_RX_PIN);/*configureUSARTRxasalternatefunctionpush-pull*/gpio_output_options_set(Print_GPIO,GPIO_OTYPE_PP,GPIO_OSPEED_10MHZ,Print_TX_PIN);gpio_output_options_set(Print_GPIO,GPIO_OTYPE_PP,GPIO_OSPEED_10MHZ,Print_RX_PIN);}/*!\briefinitilizetheUSARTconfigurationofthecom\paramnone\param[out]none\retvalnone*/voidusart_print_config(void){/*enableUSARTclock*/rcu_periph_clock_enable(Print_USART_RCU);/*US

首次用vscode来烧录（国产化的需要），仿真器是ArmV9，芯片是GD32F103ZET6，烧录配置想用JlnkSWD，但是用USB连接pc和仿真器--GD开发板后，点击vscode中的烧录，出现如下错误：网上找了很多帖子还没有解决，有思路的请指点下，谢谢

出错信息如下：请大家看看有没有思路，谢谢。或者用vscode环境+Jlink烧录GD32的程序，是怎么个步骤烧录的？

以前用ADC很少用内部基准,都是尽量加一个431什么的,多用一个ADC通道读431再换算这次偷懒用了VREFINT,结果发现每次复位之后ADC采样结果相差挺大,于是单独把VREFINT的值输出到串口再换算成电压试试.一看吓一跳,标称1.2V,最低只有1.138V左右,最高1.207V左右,每次复位都不一样,复位之后倒是挺稳定的.是我哪里设置得不对吗?还是这东西就这样...
