Troubleshooting checklist
- [Yes] I read the README (on master) thoroughly
- [Yes] I ran the MAX30100_Tester and I'm going to paste the output down below
- [Yes] I filled in all the details of my setup down below
Description of the issue
I can't merge MAX30100 code with any other sensors i always get 0s
Output from MAX30100_Tester example
Details of my setup
The issue is kinda complicated as MAX30100 had been modified by desoldering the 3 resistors 4.7k and making external resistors .. I have been trying to make MAX30100 works with another codes but with no use on Nodemcu v2 / Arduino Uno .. tried to just upload the data on Ubidots but i get zeros always .. i even tried to use Arduino as master and send data through Serial communication but no use i get zeros value .. I traced the code all along on the MAX30100 code alone if i added delay more than 90 ms it will not detect any beat ... So is there anyway i can merge MAX30100 with ECG Sensor AD8232 and upload the data to Ubidots ?
