Rex Ching / Mbed 2 deprecated MedtricsIOECG

ECG data acquisition with Analog device frontend and Redbear nano BLE

Dependencies:   BLE_API mbed nRF51822

Fork of BLENano_SimpleControls by RedBearLab

Reference Design

2 channel EKG with Redbear BLE reference and Analog Device amplifier to generate RAW EKG data fed into Medtrics MaaS service . Medtrics API can consumer raw input with given parameters of ADC sample frequency and scaling factor

Specification

  • Application Processor: nRF51822/BLE , Analog frontend: AD8232 /
  • Input Analog Voltage = 3.3V
  • 10 bit ADC input range = (0-1023) or scaling factor= 3.22mV/unit (this is ADC resolution)
  • ADC sample frequency (BLE pull rate) = 250Hz (4ms per sample)
