- Check with a switch case to see what happens through the code.
- Check if the pin has been assigned as output pin instead of input pin inorder to read from the pin.

mypi = raspi; cam = cameraboard (mypi); ButtonPress= readDigitalPin(mypi,23); if ButtonPress img = snapshot (cam); img = imagesc (img); end
I want to click photos through raspberry pi with raspberry pi camera board in MATLAB when we press push button. I wrote a MATLAB code for this which is shown in below figure.
Even if I connect the digital pins directly to wires still my readDigitalPin shows 0.
Could you please help me with this?
