lamik / max30102_stm32_hal Goto Github PK

I am using the stm32 blue pill. Thanks for sharing a quick start, this sensor has not been easy! Now hooking up my sensor and inspecting it via stm32cubeide live I can see in the Max30102_Init(huart**) everything is HAL OK, which is good..

going into Max30102_Task(void) the conditional block if(IsFingerOnScreen) is always false and never runs? where is this global var even located as it never is assigned and never takes on a value from what I see? Even if I comment that conditional out and run the below code the only values I see here are

uch_addr	uint8_t	13 '\r'	
uch_addr@entry	uint8_t	13 '\r'	
uch_data	uint8_t	36 '$'	

so from the task I can ever switch(StateMachine)
but after the sensor is unable to detect my finger? any idea why?

the variables that I have created

    uint32_t heartRate = Max30102_GetHeartRate();
    uint32_t spo2 = Max30102_GetSpO2Value();

never contain any values ...

to confirms the SDA and SCK lines are hooked up properly, 3.3 V coming in along with the pull-up resistors attached. I can see the LED flash between cycles other than that I am unable to get anything working on it

Hi.
Can you tell me the hardware connection to reproduce the code?
