Serial port communication between PC and NIOS II based on Delphi
Zhi Yan · Journal of Naval University of Engineering · 2008
The communication interface of NIOS II and the advantage of Spcomm under Delphi were introduced by comparing SOPC with MCU.The level conversion circuit was built for host computer RS232 serial communication,and the initialization code of serial communication of slave computer was offered.In order to enhance the ability of anti-interference in communication,the communication message protocol was designed and defined in the scheme.The concrete data processing for messages on both sides was given.The results of practical operation show that the strategy is excellent in error to-lerance and stability.
