Serial Rx problemJohn van Kleisterlee over 15 years ago I have a strange problem in my code. I cannot receive characters via the serial port. I've read up on the TI and RI interrupts and I think I am handling these correctly. The program goes to the serial I/O isr, but just sits...
send_xchar():发送一个 XON 或 XOFF 字符,用于流控。 stop_rx():停止接收数据。 enable_ms():启用串口的 modem 状态检测功能。 break_ctl():发送一个 break 信号。 startup():初始化串口硬件。 shutdown():关闭串口硬件。 flush_buffer():清空串口的缓冲区。 set_termios():设置串口的终端参数。 set_l...

所有Arduino板至少有一个串口,数字引脚位为 0(RX) 和1(TX) Arduino Mega 有三个额外的 TTL串口如下: Serial1:19(Rx) 和 18(Tx) Serial2:17(Rx) 和 16(Tx) Serial3:15(Rx) 和 14(Tx) Arduino Due 有三个额外的3.3V TTL串口,额外串口引脚排布和 Arduino Mega 相同 Arduino Lenonardo 串口 Serial1...

Current Behavior The Matek F411 Wing with SFTSRL2 Firmare has 2x Softserial but just 2x TX no RX/TX Desired Behavior It would be better to have a third "full" serial with RX TX as Serial 2 and leave Serial 1 as TX only. Suggested Solutio...
The demos are written for Linux, some using sockets andclone()for background processing. They try to simulate real TinyFrame behavior in an embedded system with asynchronous Rx and Tx. If you can't run the demos, the source files are still good as examples. ...
