Hello everyone,
Just a simple question about button design, Do we always need pull up resistor based on the dsPIC33FJ chips? Can I just use the output port to set the pin value to 1 and then read back the value and see if the button is pushed?(I tried this in code, but looks it doesn't work:sad: or maybe I didn't do it the right way)
Thanks.
