Arduino+MAX30100(RCWL-0530) Unable to begin MAX30100

[William-An]

Hi, thank you for developing such code for MAX30100!

But as my title says, after connecting the sensor to arduino uno, the serial console shows nothing. However, after I unplugged the sensor from my breadboard, the serial console starts to print "Heart rate:0.00bpm / SpO2:0%." After I inserted some "Serial.println();" in the MAX30100.cpp, I found out that the code stopped at this line: "Wire.write(data);" in "MAX30100::writeRegister" during the "MAX30100::begin" process.

I really cannot solve, could you help me through this?

[AhmadZMQ]

yup....Arduino UNO,Mega, as well as Nano....

I'm having problems. max30100 (rcwl0530) can not work. I'm using your library max30100. and run the max30100 tester and just show it

pin max30100 vin = pin arduino v3,3 pin max30100 scl = pin arduino scl ( 4,7 R ) pin max30100 sda = pin arduino sda ( 4,7 R ) pin max30100 int = pin arduino d2 ( 4,7 R ) pin max30100 GND = pin arduino GND

this is like @mesutsaygioglu project. but I do not understand can some one help me??

[AhmadZMQ]

Hi, Is this working for him( @mesutsaygioglu https://github.com/mesutsaygioglu ).Also , you can try out by open the INT pin. As I already told you to just use max30105 ( https://learn.sparkfun.com/tutorials/max30105-particle-and-pulse-ox-sensor-hookup-guide) breakout board for convenience.I don't know whats wrong with max30100 breakout board,I didn't find any solution for him at yet.

i have problem sensor data. the sensor value jumps with a large range. how is the data sensor stable ?? anyone can help

[AhmadZMQ]

Firstly,just tell me which sensor are you using and let's explain little bit of you problem....

Hi, I saw this,It's so cool s/w and provides a simulation.It's so interesting too. Can u let me know, what type of problem u encounter.As I understand that u can use Arduino IDE to code and make compatible with Proteus by adding Arduino library to the Proteus like this (click n c-- http://www.instructables.com/id/How-to-add-Arduino-Library-in-to-Proteus-7-8/)way . 👍

Hi all, I was using MAX30102 and had the same issue. I solved the problem by using 1 pull-up resistor (4.7 kohm) for SDA pin and another one (4.7 kohm) for SCL pin. Vin was connected to 5V of Arduino and also both pull-up resistors were connected to 5V. I got these information from this link, http://mikrokontroler.pl/2017/09/14/przyklad-pulsoksymetr-max30100-plus-kamduino-uno/ Thanks,

Check if you are using max30100 or max30102.

@FelipeMdeO Which one should I use? (I have both)

To this library, only max30100.

@FelipeMdeO I am using max30100 right now and I still have the same problem.

[FelipeMdeO]

Please, look again.

In datasheet of max30102 (https://datasheets.maximintegrated.com/en/ds/MAX30102.pdf )page 11 you have Part ID = 0x15 But in max30100 (https://datasheets.maximintegrated.com/en/ds/MAX30100.pdf), Part ID is 0x11: So, you have max30102 in your board. Please, if the problem continues, send photo of your wire.

[CarlaZeine]

Hi,

You should do some modifications on the Max30100 board to work with arduino. That is because of the voltage 1.8v or 3v.

Please check the image below.

You should cut the connection between one rail of the voltage regulator and the resistor, then you have to connect the resistors to Vin.

@FelipeMdeO I think you are right! It is marked as a Max30100 but it seems to respond as a Max30102...

Do you know another library for that one ?

[FelipeMdeO]

Its because max30100 and 30102 have same pin out and foot print, so you can change one per other in ae board. U can use it: https://learn.sparkfun.com/tutorials/max30105-particle-and-pulse-ox-sensor-hookup-guide/all

hello sir this is my program when i am running this program only using max30100 sensor then it is working but if i call any other funtion in void loop it is not working i am not getting how to solve this trying from 15 days not getting answer even i searched so many articles but dint get the answer plz if anyone knows plz reply as soon as early thank you

[pahart2208]

Hi. Yes, I've struggled with this for a few days. Works fine as-is when writing to serial or LCD, but when I add anything, the output from MAX30100 stops. In my case I was trying to write to my cloud services dashboard using WiFi. I'm no s/w expert, but....Seems like the pox.update() has to run at a minimum 100Hz i.e. cycle time of <10ms. I put a couple of software timers in the code and when the code above runs, it takes between 1 and 2 ms, which is easily fast enough. However, the Wifi write was taking around 350ms and so pox.update() stopped working properly.
Now I understand the comment in the code: // Make sure to call update as fast as possible At least 100 times each second, or it won't work! So, your other function must be taking longer than 10ms which stops pox.update() working. Still trying to figure out a workaround.
Hope that helps - or at least gives some insight into the problem.

so I've been struggling with this for some time and finally able to get it working. I ordered got 2 "MAX30100" boards but 2 are not alike. turns out 1st one is MAX30100 and the 2nd one is MAX30102 so kept the max30102 aside and started working on max30100. I used an Arduino Mega. Vin to 3.3v, GND to GND, SCL to SCL, SDA to SDA and INT to digital pin 2. then I scanned for i2c devices File > examples > Wire > i2c _scanner No devices detected. then I broke the connection between SMD resistors and voltage regulator and solder a wire to those resistors ( check red circle in the picture) and connected that wire to 5V then again did an I2C device scan. -> device at address 57! then upload the max30100 debug file and it worked! then tried again the max30100 tester ---> "could not convert 'sensor.MAX30100::begin((pulseWidth)3, (ledCurrent)14, (sampleRate)1)' from 'void' to 'bool'" Sketch->include libraray -> MAX30100lib and finally got everything to work !!!
