| 摘 要： | 针对目前静态心电图机体积较大，不便于携带出诊的问题，设计一种基于MSP430F1611的便携式12导心电数据采集系统。该系统利用MSP430F1611和高速16通道24位高精度MD转换器ADS1258，采用SPI，I^2C串口通讯方式，使用DMA控制器对12导联心电信号进行同步采集和传输。实验结果显示达到预期目标。该系统可应用于便携式多道心电图机，并可连接至电脑对数据处理显示、打印、分析及诊断，大大方便心电图检测。

| Abstract: | Considering the problem that the ECG is too large to tote, the acquisition system of 12-lead ECG data bsed on MSP430F1611 is designed,which can acquire and transmit the 12-lead ECG data.Its main features include a micro-controller MSP430F1611, and a 16-channel low-noise, 24-bit delta-sigma, high speed low-power analog-to-digital converter. It uses SPI and I2C mode to transmit;DMA controller to store data.The result of experiment shows it achieves the request. And its data can accommodate with normal ECG or ... |
