Can you help, i dont know connect this sensor, i put the connections but the led not put on. Thank you

FelipeMdeO commented 5 years ago

To have light in led is necessary configure it to do. Read max30100 datasheet and you will understand better.

yes, I know. But max30100 not working, any peoples say that i need desolder the resistences, and put 4.7kOhms. What do you know?

sorry for my english, I speak spanish

FelipeMdeO commented 5 years ago

Sorry for my delay and no problem for your english, I no speak english well yet, I speak portuguese...

So... about change the resistor, wait to do it, this will be last thing to do.

Can you communicate with sensor ? You can use library i2c scanner to do it. - https://playground.arduino.cc/Main/I2cScanner/ Other method to test comunnication is uncomment line 18 of sketch: //pulseOxymeter->printRegisters(); and use serial monitor. If it work: Try comment line : pulseOxymeter = new MAX30100(); and uncomment line: //pulseOxymeter = new MAX30100( DEFAULT_OPERATING_MODE, DEFAULT_SAMPLING_RATE, DEFAULT_LED_PULSE_WIDTH, DEFAULT_IR_LED_CURRENT, true, true );

Post your result, please.

celciusjj commented 5 years ago

Ok I try that. Dont worry, thank you for help me.

I have two questions. 1- what scheme did you use to mount the circuit

2- Did it work with the soldered resistors of the max30100?

tomorrow I try the communication l2c, today i am a little busy.

FelipeMdeO commented 5 years ago

1- what scheme did you use to mount the circuit: I use standard connection. At this time I´m not using Arduino, but NXP Freedom kl02 board. I only connect Vcc, GND, SDA and SCL and it worked. 2- Did it work with the soldered resistors of the max30100? I´m using this board: -> https://pt.aliexpress.com/item/WS16-NEW-MAX30100-Heart-Rate-Sensor-Click-Heart-Rate-Oximeter-Pulse-Sensor-Pulsesensor-Module-For-Arduino/32722466324.html?spm=a2g0s.9042311.0.0.556cb90aJzwqFv For it I no need do any modification in board.

celciusjj commented 5 years ago

Oh, ok i am use the max30100 green or rcwl - 0530, this is the best tutorial that i found. https://www.teachmemicro.com/max30100-arduino-heart-rate-sensor/

FelipeMdeO commented 5 years ago

uhnnnnnn... Basead in your tutorial, you will really need remove pull ups connecteds to SDA and SCL and use resistor to +5V to do it work in Arduino. At my case, maybe work because my micro controller is +1.8 to 3.6 V. So, do it. Remove pull ups and use external resistor connected between +5V and SLC and +5V and SDA and try use Arduino library.

I wait for news! Good luck.

Verify your baud rate of serial.

I have 115200, what value i put?

FelipeMdeO commented 5 years ago

You need put same value in serial monitor. Do you verify it?

celciusjj commented 5 years ago

Yeah i have this value, now if i put RD to ground the led start glow but in program is failed. Is so rare... Sometimes the LED is bright, others do not shine or shine little.

in this post https://github.com/oxullo/Arduino-MAX30100/issues/16 saikapilan have the same problem.

FelipeMdeO commented 5 years ago

You tried connecting just VCC, GND, SDA and SCL? I just use that pins. And... you put pull ups?

celciusjj commented 5 years ago

Yeah, i am use this pins, but the led not put on, when i put RD to ground the led is glow, also when i put my finger above him.

Sometimes, when connect arduino the led put on, but inmediatly this put off. Jajaja omg

celciusjj commented 5 years ago

Forget the previous comments, I turn on. Now let's look at the data that the sensor delivers.

look this, I put the finger to take the pines with the sensor.
