293 – Displaying BPM Through Seven Segment Displays

This Application Note demonstrates how to sample and display calculation channel data through external devices such as LED’s or 7-segment displays via UIM100C digital output ports. In this exercise, BPM data derived from an analog ECG channel is displayed through a 7-segment display matrix.

Associated Applications

• Amplifiers & Interfaces - Use BIOPAC amplifiers with MP Systems, as stand-alone devices, or with 3rd-party flow meters, force plates, sono-micrometers, telemetry equipment, metabolic carts, etc.
• ECG: Cardiology - Connect up to 16 ECG input leads with MP160 system. Use automated analysis features for HRV, RSA, to classify heartbeats, identify arrhythmias, and perform ECG averaging.
