Conversion device and method for hetero-serial data to standard asynchronous communication wave shape

Abstract

A conversion device converting heterotype serial data into standard asynchronous communication waveform comprises an input module, a judging module, a processing module and an output module which are arranged inside a singlechip and are connected in series, as well as an interrupt processing module, wherein the input end of the interrupt processing module is connected with the other output end of the processing module, while the output end is connected with the output module. The conversion device completes reshaping of low level data waveform through the interrupt processing module, thereby realizing the conversion of the entire waveform and effectively overcoming the disadvantage that the waveform signal formed during bus transmission can not be directly received by a singlechip port; meanwhile, the data output end of the data receiver arranged inside a data transceiver is simply connected with the periphery of the singlechip, which omits the complex connection of peripheral circuit and is propitious to product integration. The invention also designs a method for waveform conversion.
