The analyzer itself is a LPC-E2294-RB development board from Olimex. This development board uniquely features four CAN controllers and a UART to USB conversion chip capable of RS-232 with speeds exceeding 1Mbits/s.
Controller Area Network (CAN) is the de-facto protocol for communication between embedded devices. It was developed by Bosch in 1983 and was designed originally to be used in automotive industry where many systems within a car need to be communicated with a central ECU. CAN or CAN-bus is a vehicle bus standard design to allow microcontrollers and devices to communicate within a vehicle without a host computer. CAN is a high integrity serial data communications bus for real time control applications. Operates at data rates up to 1Mbits/s over links up to approximately 40m.
