What does Overrun error in UART and considerations to overcome? Overrun error occurs when another byte of data arrives even before the previous byte has not been read from the UART's receive buffer. This is mainly due to time taken by CPU to service the UART interrupt in order to remove ...
1:已准备好读取接收到的数据 ORE:上溢错误 (Overrun error) 0:无上溢错误 1:检测到上溢错误 UART通信接口 UART常见通信接口有:TTL、 RS232、 RS485。在编程时需要考虑通信接口方式,在长距离通信的时候,需要考虑线路上的延时,如果操作不当也会导致数据丢失。 1.TTL TTL比较简单,就是直接连接UART的Tx和Rx引脚...
S3C2410的每个UART都有7种状态,分别是:溢出覆盖(Overrun)错误、奇偶校验错误、帧出错、断线错误、接收就绪、发送缓冲空闲、发送移位器空闲。它们在UART状态寄存器 UTRSTATn / UERSTATn 中有相应的标志位。 波特率发生器 每个UART控制器都有各自的波特率发生器来产生发送和接收资料所用的序列时钟,波特率发生器的时钟源...
There is a race condition present in the stm32 port that relates to the way the UART overrun (ORE bit in USART status register) is handled in the IRQ service routine. If this condition is met, the pyboard completly locks up and cannot be...
