Laboratory board demonstrates CAN bus

The goal of this thesis, is proposal of the laboratory board demonstrates communication by the help of bus CAN. Laboratory boards, controlled with microprocessor, will be send statuses inputs and outputs with each other. Also it will can be transmit and receive messages by the help of the serial port RS-232. With protocol CAN will be send this information: Temperature, Lighting, Analog input 0 - 5 V, Analog output 0 - 5 V, Digital input level TTL and digital output type open collector
