Revision history [back]

for me worked so far a single character read/send stable over serial, especially when ftdi or wirless adapters where in between. So I thought something like a ros node would generate the message but the serial connection itself would be reduced to a bare minimum like char or int16 for values from/to the arduino. The ros_arduino_brdige seems to do something like that. Do you know where ros_arduino_msgs.msg comes from in that code ?
