GD32F405RG 芯片 DMA 初始化代码如下。 发现 USART_DENT_ENABLE 和 USART_DENR_ENABLE 无法识别。 已经加载 "gd32f4xx_usart.h" "gd32f4xx_dma.h" 2个文件。依旧不行。 有知道是什么问题吗？

各位前辈好。第一次用AC78406芯片。使用uart0 uart1中断接受不定长数据。单个串口可以接收了。两个串口同时使用只有先初始化的那个串口可以进入中断。请问哪里配置有问题吗？代码是用AutoGen Studio生成的。[color=#dadada][backcolor=rgb(30, 30, 30)][font=Consolas,
