固件在线升级BootLoader 的主要功能是加载主程序,但为了支持在线升级,它需要实现对 Flash 的擦除和写入功能。通过网络(如 WiFi、以太网)或串行接口(如 UART、CAN),将新固件下载到设备中并写入 Flash,完成程序的更新。 分区存储管理在复杂的应用中,可能会使用 Flash 的不同分区存储多个固件版本或配置文件。Flash Writ...
例如UART、1284等,它的总线架构不像 AHB支持多个主模块,在APB里面唯一的主模块就是APB 桥。再往下,APB2负责AD,I/O,高级TIM,串口1;APB1负责DA,USB,SPI,I2C,CAN,串口2345,普通TIM。 cortex-M3、cortex-M4内核是由ARM公司提供的。芯片其余外围是由ST公司设计完成的。
HAL_UART_Receive_IT(&huart2,(uint8_t *)&value,1);//程序不会在这个语句停留,直接会按照中断方式把接收数据存放在value中,但是这个语句只能使能一次串口中断。所以要在中断服务函数或者回调函数中重新使能 串口接收功能3: if(HAL_UART_Receive_IT(&huart2,(uint8_t *)&value,1) != HAL_OK){ //这...

Combine UART + DMA for data reception Now it is time to understand which features to use to receive data with UART and DMA to offload CPU. As for the sake of this example, we use memory buffer array of20bytes. DMA will transfer data received from UART to this buffer. ...
This is the 4th tutorial in the STM32 UART Series. In this tutorial we will use the DMA to receive the data in the normal and circular mode..
