 27 Oct 2007 18:15 ECG PIC |
|
|
|
Hello guys
I've designed a circuit based on PIC16F628 that counts the heart beat of humen in beat per minut bpm, with a bad luck I've stucked in the conversion of pulses from secondes to minutes as the heart beat must be in minut.
Note: I'm using assembly language.
Could any body help or provide a full codes please.
Regards.

If you have time between pulses in miliseconds, you can convert it into bpm according to formula:
x=60000/T_ms
T - heartbeat period in ms
but try to average time from more than one pulse to avoid disturbances.

| Count the time in tens of seconds between two input pulses and use a table to convert the value into puls/minits (retlw p/m) so you have no mathematical problem
