ECG data acquisition with Analog device frontend and Redbear nano BLE
Dependencies: BLE_API mbed nRF51822
Fork of BLENano_SimpleControls by
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)
Reference IOS and Android app will be online soon!
