Arduino Yun Bridge

Linino 的 console /dev/ttyATH0
Arduino 使用 YunSerialTerminal

Arduino 使用 Bridge, 在 Bridge.cpp 中
Arduino\libraries\Bridge\src\Bridge.cpp
void BridgeClass::begin() {
  uint8_t quit_cmd[] = {'X', 'X', 'X', 'X', 'X'};
  transfer(quit_cmd, 5);
  stream.print(F("run-bridge\n"));
}

Linino 執行 /usr/bin/run-bridge

/usr/bin/run-bridge
exec python -u bridge.py 2> /tmp/bridge.py-stderr.log

/usr/lib/python2.7/bridge/packet.py

使用 stdin stdout

/usr/lib/python2.7/bridge/mailbox.py

json_server = TCPJSONServer('127.0.0.1', 5700)

/usr/lib/python2.7/bridge/mailbox.py

def __init__(self, port=6571):

  utils.try_bind(server, '127.0.0.1', port)
