Max30003 problem with SPI #12
Comments
Hi, I'm a retired physics teacher, thou I worked in the physics labs at Havana University for many years. |
@adelalfusail Please make sure that the CS lines are separate and only one device is selected at a time when the SPI bus is used. |
I'm sorry, but I'm new to all this. I have made two or three working
projects (one is the PulseSensor) but this one is proving too difficult.
I have googled "CS lines" and found nothing. I do not know what that means.
Also, I do not understand your " only one device is selected at a time when
the SPI bus is used". Will you send me to a good tutorial where all this is
explained? Thanks for your time.
My goal is to make a Heart Rate Monitor that measures the Interbeat
interval to obtain the HRV in real time.
