This is the 4th tutorial in the series on the UART peripheral of STM32 Microcontrollers. In this series we will cover different ways of transmitting and receiving data over the UART protocol. We will also see different UART modes available in the STM32 microcontrollers and how to use them....
In addition, this UART emulation uses DMA to minimize CPU usage. This application note provides a basic example of communication between a hardware and a software UART, as well as a summary of CPU load and firmware footprint. The STSW-STM321...
波特率是有一定的容错范围的,例如,STM32配置成115200波特率,每10ms发送一个30字节的字符串,串口芯片用的CH340,上位机波特率设置成113000-121000也可以接收,无乱码,差不多正负2000的波特率,这容错范围也太大了,当然如果发送频率太快,数据量太大,误码率肯定会大大增加,所以还是建议通信双方使用同样的波特率以减少误差...
