I want to create c code for max30100

Question

Hi, i am using max30100 sensor,but i don't know how to operate ,i want to create c code for max30100,i want not use max30100 labirary.plz help me.sir

The MAXREFDES117#: Heart-Rate and Pulse-Oximetry Monitor is based on the max30102:

https://www.maximintegrated.com/en/design/reference-design-center/system-board/6300.html/tb_tab2

If TL;DR then buried within that webpage is a link to the library code:

https://github.com/MaximIntegratedRefDesTeam/RD117_ARDUINO/

PS: Of course you can also simply open up Arduino go to Sketch -> Include Library -> Manage Libraries... and type in "MAX301" and you'll find a number of 3rd party libraries.

Nittu, here are 2 people that have done it before: In c++. https://github.com/kontakt/MAX30100/tree/master/src You could use the exact same code, but have to turn the class members into C functions. from void MAX30100::setLEDs(pulseWidth pw, ledCurrent red, ledCurrent ir){
 uint8_t reg = I2CreadByte(MAX30100_ADDRESS, MAX30100_SPO2_CONFIG);
 reg = reg & 0xFC; // Set LED_PW to 00
 I2CwriteByte(MAX30100_ADDRESS, MAX30100_SPO2_CONFIG, reg | pw); // Mask LED_PW
 I2CwriteByte(MAX30100_ADDRESS, MAX30100_LED_CONFIG, (red<<4) | ir); // write LED configs
} to: void MAX30100_setLEDs(pulseWidth pw, ledCurrent red, ledCurrent ir){
 uint8_t reg = MAX30100_I2CreadByte(MAX30100_ADDRESS, MAX30100_SPO2_CONFIG);
 reg = reg & 0xFC; // Set LED_PW to 00
 MAX30100_I2CwriteByte(MAX30100_ADDRESS, MAX30100_SPO2_CONFIG, reg | pw); // Mask LED_PW
 MAX30100_I2CwriteByte(MAX30100_ADDRESS, MAX30100_LED_CONFIG, (red<<4) | ir); // write LED configs
} The 2 data members can become variables in your C file: uint16_t IR = 0; // Last IR reflectance datapoint
 uint16_t RED = 0; // Last Red reflectance datapoint If you do not like that library, then there is this python code: https://github.com/mfitzp/max30100/blob/master/max30100.py It can be translated 1 for 1 into C functions. Replace i2c.xxx() with the wire functions.
