Driver for Maxim MAX30101/MAX30102 Pulse Ox/Heart Rate Sensors

[tammymakesthings]

The Maxim 30101/30102 are sensors that measure pulse ox (blood O2 saturation) and heart rate. DigiKey has an evaluation board for this sensor, as do other vendors such as SparkFun and MakerFocus. As near as I can tell, all of these boards communicate using i2c, and the protocol is pretty well documented in Maxim's data sheet.

I've found an Arduino library which supports this sensor, but nothing for CircuitPython. I'm planning a project which will use this sensor, so I'd like to work on porting the Arduino library to CircuitPython. (I've never written a driver for something before, so I'd also love help 😄.

When I wrote my first CircuitPython library, which was a complex one, I referenced the Data Sheet and the Arduino Driver and looked at other CircuitPython libraries and the learn guides for reference.

Oh and I asked questions on Discord if I got stuck, but I think that was mostly at the end with the publishing part of it.

I would like to know if anyone is still interesed to porting, from Arduino library or maybe make new driver in CircuitPython ( or also for MicroPython ) of Maxim 30101/30102 chip.

I’m still interested in working on this, especially since I am currently furloughed from work. Happy to have collaborators!

@tammymakesthings what do you need to get started? I'm sure we can find folks to help.

@tammymakesthings I just got a maxrefdes117# from digikey. it has the max30102. i could help write the library if you are interested. I so, do you have your current work within a github? Thank you.

I would love the help. I have a GitHub repo set up, but nothing in it yet. I will add the people who have expressed interest, and then we can figure out a path forward. Thank you

Hi to all. I believe that it may useful have a file with raw data ( only samples data ) and to know which of them are the heart rate and SpO2. In this manner we can develop and test some algorithms before to try the sotfware in the bare-metal. Do somebody has the file or know where is possible to get it ?

by using the maxim reference code, i built a rough circuitpython class, @tammymakesthings, which i can send to you if you're interested

i'm working in project that uses max30102 using micropython ...... but unfortunately i didn't found its library ...... i just found the max30100 library and most people said it doesn't work !!

any help please ??

So looks like i also want to use this sensor and have found no library...
