Heart rate sensor MAX30102

[astanapane]

well noted,

1. Changed the crystal and used only the interal

CONFIG FOSC = INTIO67 ; Internal oscillator block

2. i've changed the circuit from 3.3V which was the output of the Display, and supplied the circuit with the PICKIT2 5V. I checked that this specific circuit draws up to 80mA. (USB 2 can deliver 100mA and at its maximum 500mA)

MAX30102 can be supplied with 5V as from the following link.



I have also applied the fix they have from the given link, and measured the output voltage at 1.8V which goes to the MAX30102 chip on the tiny board. So everything looks good now.
