Design and Implementation of A Low-Cost ECG Monitoring System Using ARM Cortex-M4 Family Microcontroller
Shahrokh Sani
Abstract
A prototype of a low-cost electrocardiogram (ECG) monitoring device has been designed and implemented. We used Texas Instruments TM4C123G LaunchPad as a low-cost ARM Cortex-M4 based microcontroller, the AD8232 board as a cost-effective single lead ECG sensor, and Nextion 3.2" touch screen Liquid Crystal Display (LCD) as a monitor. A moving average filter was designed and applied to smooth the signal and get a high-quality ECG signal. Experimental results indicated the feasibility, validity, and reliability of the design.
