개소료DSP(이TMS320F2812위례)Flash정서재선승급방법적총체설계사로,이급상위궤、하위궤량부분적설계.본방법선택기우 RS422 통신접구실현,방편쾌첩차안전가고,가제고DSP Flash정서재선승급적역용성화가조작성,이경과실천검험.
This paper introduces the overall design ideas of the method of DSP (takeing TMS320F2812 as an example) Flash program upgrading online and the designs of the PC and the PLC. The upgrading online method is based on RS422 communication interface, which is convenient and safe. It can improve the usability and operability of DSP Flash application upgrading, which has been tested in practice.
