Hardware flow is typicallycontrolled by the DTE device, which could be considered a‘master’ device. In the case of a DTE-to-DTE configuration, either device can act as a master. 发送方DTE1,通过自己的RTS引脚,发出发送请求给DTE2: When one DTE devicewishes to transmit data, the DTE device...

Hardware flow control 有两个模式:1、auto flow control;2、software configured hardware flow control。 Hardware flow control Auto hardware flow control由auto-CTS和auto-RTS控制,auto-RTS在receiver block中产生,如果RX FIFO的数据量少于阈值,RTS is active,发送设备(外部的UART)可能会多发1byte数据,这是因为当...
We have a product that is nearly ready to ship and only waiting on a resolution to the hardware flow control not working properly. 0 Kudos Reply 10-29-2024 02:35 AM 993 Views xiangjun_rong NXP TechSupport Hi, This is the timing I use the scope Trigger mo...
USART_HardwareFlowControl:硬件流控制 USART_Mode:单/双工,即收发状态 4、NVIC配置 5、开启中断并且初始化NVIC NVIC_Init(); USART_ITConfig();//使能相关中断 6、使能串口:USART_Cmd() 7、编写中断处理函数 USARTx_IRQHander(); 8、串口数据收发
