Hi,
ADS1198 IC paceout pins (TESTP_PACE_OUT1 & TESTN_PACE_OUT2), i have connected to a hardware pace detection circuit
(Differentiator, window comparator, SR latch) and SR latch output is connected to a GPIO pin of a Micro controller (STMicroelectronics)
1) when a pace pulse event occurs, SR latch output changes it state form LOW to High which is seen by MCU, now how do i plot this event along with ECG signal on my device display(my ECG device has a display to show ECG waveform), because what if a pacemaker pulse event occurs before the AFE ADCs sample the ECG signal, packetize them then send over SPI interface and MCU plots it on the Display ?
How to integrate a pace maker pulse detect event along with the ECG waveform on a display?
What is the logic?
