Question
JayLee
my project goal is to design a 'heart rate module' using zed board and ppg sensor.
I'm gonna use Pmod as ADC for converting the analog signal from the ppg sensor to the digital signal so that the zedboard would be able to process it.
there is a problem at this point.
my module gets a '12-bit signal' as input,
but I found out that the Pmod provides the digital output in serial peripheral protocol.
the input of the module has 12-bit range, but the output of pmod(which will be connected the module as a module input) is only 1-bit range.
i think their bit range differs, which shouldn't
how can i solve this problem?
ps. it's my first time to ask something online in English. so please understand even if my English is not good.
