Wiring for NodeMCU-esp8266

anwarbashir commented 7 years ago

Troubleshooting checklist

[x] I read the README (on master) thoroughly
[x] I ran the MAX30100_Tester and I'm going to paste the output down below
[x] I filled in all the details of my setup down below

Description of the issue

Output from MAX30100_Tester example

Details of my setup

Arduino hardware: nodemcu-esp8266
MAX30100 breakout: MAX30102/MAX30100 Heart Rate Breakout Sensor Blood Oxygen Transducer for Arduino
Arduino framework version: 1.8.3
MAX30100 library version: 1.1.0 I have attached 3.3V and GND. I have connected SDA - GPI04(D2) nd SCL - GPI05(D1). I have added the line Wire.begin(4, 5); //sda, scl. I ran the MAX30100_Tester code. I am getting FAILED: I2C error. Do you think I need pull-up resistors on SDA/SCL or am I using wrong pins or is something else wrong?

Would be graet if I could get your code working with my nodemcu-esp8266.

Hey @anwarbashir in the readme it is explicitly stated that the most critical thing to check are the two 4.7kOhm pullups on SDA/SCL lines.. Note also that MAX30102 is not supported, so make sure you have a MAX30100 on your breakout. I do not support esp8266, but if you make it working please let me know

Hi, sincere apologies, I should have read the information properly. I am trying to get an ESP32/ESP8266 to interface with MAX301002 that has breakout with circuitry already attached. To begin the process of developing a heart-rate monitor interface I have connected to a Raspberry Pi and using an IC2 library available at http://wiringpi.com/reference/i2c-library/ I am begining the journey. I have published my code on github at https://github.com/anwarbashir/max301002-raspi. At the moment it simply obtains the part id (I think it works but I am checking). Please feel free to keep an eye on this... Again my apologies for not reading your documentation properly even though you have made the process clear.

No prob! I'll keep an eye on your repo!

hi, I guess am able to interface with MAX30100 module using NodeMCU ESP12 config. Am getting HeartRate and SPO2 value(%) appropriately as expected. Please let me know for any help and if you are still stuck with this. Will post the details soon.

@madhujiot can you please help me with those codes ? i m stuck withit , i dont find libraries to use.

madhujiot commented 6 years ago

Sure, I am stuck with some other work. In couple of days, I will post there.

thank you @madhujiot

Praveen-dhanasekae commented 6 years ago

@madhujiot i really need this . Can you upload it faster? i need it to move to the next step .My schedule to finish it is very less .So please make it faster.

madhujiot commented 6 years ago

really Sorry as I wanted to send now, but before that I thought I will check with my Nodemcu, its crashing due to some library issues or some other recent updates on my IDE, not sure.. will rectify and send.

ok @madhujiot try to send it soon ... can you tell me like what were the libraries used by you ?i ll try it from my part..

madhujiot commented 6 years ago

hi Praveen,

I used MAX300 library from OXullo only (MAX30100_PulseOximeter.h) with PulseOximeter as the interface and wire.h for I2C operations.

I need to cleanup a lot my laptop before I re-instantiate the Arduino and sensors setup, it may take a while.,
