Content
Single Edge Nibble Transmission (SENT) is a promising low-cost solution for communication between off-ECU sensors and a microcontroller. First, this paper analyses the advantages of digital sensors with a special focus on position sensors. The possible integration of SENT in other application fields (such as pressure sensors) is also discussed. Secondly, it describes possible solutions for handling SENT communication on microcontrollers and it gives practical examples based on Infineon's TriCore and XC2000 families. It discusses the constraints and limitations on software level and how they could be solved by dedicated hardware implementations. Finally, this paper presents the Short PWM Code (SPC) protocol, which is a further extension of the SENT protocol. SPC aims at increasing the performance of the communication link and reducing system costs at the same time. By allowing bidirectional communication, SPC opens the way to new system relevant functionalities.
