I'm trying to run TCS3200 color sensor on raspberry pi 4 and node red.
the color sensors outputs a frequency based on the light intensity
I've tried running the normal GPIO In and removed the debounce, with a function to only pass through new output, and an interval length node,
but the GPIO IN without a debounce just overloads the node red.
is there a way for me to just read GPIO IN(using interrupt preferably) on a function node to get the time of rising/falling edge?
maybe there is a node that can read the frequency/period of GPIO in,
or maybe there is a node that is used for this type of color sensor
