First, create a receiving buffer of 26 bytes called UART2_rxBuffer outside the main() function. This will hold the data whenever STM32 will receive data via UART interrupt. uint8_t UART2_rxBuffer[26] = {0}; UART Interrupt Call Back Function The HAL_UART_RxCpltCallback() function is ...

I have this code that initiates my UART channels with DMA at startup: if( HAL_OK == HAL_UART_RegisterRxEventCallback( m_configuration.huart,
在HAL库中,几乎每初始化一个外设就需要设置该外设与单片机之间的联系,比如IO口,是否复用等等,可见,HAL库相对于标准库多了MSP函数之后,移植性非常强,但与此同时却增加了代码量和代码的嵌套层级。可以说各有利弊。 同样,MSP函数又可以配合句柄,达到非常强的移植性: void HAL_UART_MspInit(UART_HandleTypeDef...
UART，全称：Universal Asynchronous Receiver/Transmitter，是通用异步收发器，在USART功能的基础上，裁剪掉了同步通信功能，其主要特点：异步通信全双工通信无需外部时钟信号 3. STM32 F103ZET6串口资源 STM32 F103ZET6芯片，有5个USART接口，数据手册可在官网查询：https://www.st.com/zh/microcontrollers-...
