| Abstract: | A design of ECG signals acquisition and storage system based on TMS320LF2407A DSP is introduced. The system＇s sampling accuracy has been improved by means of AD7858 which is an external 12-bit AD converter. The ECG datas of patients＇ can also be gatherd timely.What＇s more,patients＇ hearts state can be truly reflected throug digital filtering.Communication with the host computer can be established by way of the serial circuit. Compared with pc and single chip micro computer,this system itself has low -power,little cost,good real -time advantages and so on. |
