An autonomous sailboat control system is developed based on PC/104 and ARM for motion control precisely.The functions of ARM collect multiple real-time signals from individual sensors simultaneously, delivering the data to PC/104.And the PC/104 process the original data from ARM through algorithm, give order series to ARM at particular periods,and then ARM can produce Pulse Width Modulation and high or low level signal to motivate the actuators. PC/104 is chosen to be the central processing unit because of ...
