用串口助手发送8个字节的数据，在接收中断里面通过DMA搬运数据。但接收的数据有问题，第一个字节的数据搬运2次，最后一个字节的数据丢失。void uart_init(void) { UART_InitTypeDef uart0_config; GPIO_InitTypeDef GPIO_InitStruct; // DMA_InitTypeDef uart0_dma_config;

[i=s] 本帖最后由 tyw 于 2024-10-23 11:35 编辑 [/i] 首先描述一下现象：翻译 [align=left]搜索[/align][align=left]复制[/align] 在硬件上使用了PC10（TXD）和PC11（RXD）两个引脚，这两个引脚是可以使用USART3 以及UART3的，目前可以正常使用USART2进行数据收发的工作，但是无法使用UART3进行数据收发，仿真器连接的时候可以看到UART3的寄存器可以正常的初始化且配置正确，说明UART3的时钟和引脚设置应该是没有问题的，也可以正常进入串口发送的函数，但是数据传输到发送函数后就没法正常传输出来，这个问题很奇怪，不知道大家是否遇到，下面是串口3的初始化的代码。 硬件原理图如下： [img]https://bbs.21ic.com/data/attachment/album/202410/23/094325qwa5hr7a3hxhg7ao.png[/img] 相关的代码如下： [attach]2307392[/attach] [url=https://bbs.21ic.com/data/attachment/album/202410/23/094209e8zdbqhtykkphkq6.png][img]https://bbs.21ic.com/data/attachment/album/202410/23/094209e8zdbqhtykkphkq6.png[/img][/url] 请问大家有有没有遇到相同的情况？

编译错误如下：./GD32F30x_Peripherals/CMSIS\core_cmFunc.h(592): warning: unused parameter 'fpscr' [-Wunused-parameter] 592 | __attribute__( ( always_inline ) ) __STATIC_INLINE void __set_FPSCR(uint32_t fpscr) | ^ 1 warning generated. 如何解决？

IAR8.10.1的版本，雅特力单片机用AT_LINK仿真时报错probe not found,驱动卸载后重新装也是一样

有哪位佬有AT32F403ARCT7最小系统外围电路的原理图，想画一个最小系统板玩玩

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,
