Pulse HR sensor

Right now i have MAX30100/MAX30102 but i don't like interface, but i try to implement it, for HR data, in 50 samples per second, i need 4*50 byte, even if i use 16bit data

Note that the ULP program can only use lower 16 bits of each 32-bit word in RTC memory, because the registers are 16-bit, and there is no instruction to load from the high part of the word.)

for 4 seconds i need 800 bytes (i hope it fit to slow memory)
