Lesson plan

Byteflight

Byteflight is an automotive databus created by BMW and partners Motorola, Elmos Semiconductor and Infineon to address the need for a modernized safety-critical, fault tolerant means of electronic communication between automotive components. It is a message-oriented protocol. As a predecessor to FlexRay, byteflight uses a hybrid synchronous/asynchronous TDMA based means of data transfer to circumvent deficiencies associated with pure event-triggered databuses. It was first introduced in 2001 on the BMW 7 Series (E65). Eclipse 500 jet aeroplanes use Byteflight to connect the avionics displays.
