| Abstract: | TMS320F240 is a 16 bit fixed-pointed digital signal processor controller,it is a member of TMS3202X series of TI. The serial communication interfac(eSCI),one of peripherals of TMS320F240,has various appli-cations in the design of DSP communication because of its simple struture and convenience. The paper simply introduces the structure of SCI,interprets a method of implementing communications between PC(host) and DSP(slave),and designs a display circuit to examine data communication simultaneously. The method has been proved to be credible by practise and has good reference of relative works. |
