RE: programing the Max30105 with nrf52840

I would recommend you to ask about this in some C/C++ specific forums.

By the way, if you browse DevZone, you will find already written drivers for the nRF5 SDK and MAX30105:

https://devzone.nordicsemi.com/f/nordic-q-a/42526/trying-to-start-developing-driver-for-max30105
https://devzone.nordicsemi.com/f/nordic-q-a/43624/arduino-twi-to-nrf52-twi-conversion
https://devzone.nordicsemi.com/f/nordic-q-a/49882/how-to-interface-external-twi-sensor-max30105-with-nordic-thingy-52-application-source

If you're using NCS, you can use the sample <ncs location>\zephyr\samples\sensor\max30101. I'm not sure how different max30101 is from the max30105, but you might have to modfiy it a little. In addition you need to add an overlay file for the nrf52840dk.

Best regards,

Simon
