LPC MicrocontrollersのトピックUnable to read GPIO pins. https://community.nxp.com/t5/LPC-Microcontrollers/Unable-to-read-GPIO-pins/m-p/835609#M33338 <HTML><HEAD></HEAD><BODY><P>I am not understanding how to read GPIO pins using the LPC 4370, I am unable to get the right reading. I am trying to give a DC supply but am not able to get any proper output, it always gives me 0, meaning the input is always low, even when I am giving a DC of 3.3V. Do I have to supply a greater voltage? I am totally left clueless. I am using GPIO1_0.</P></BODY></HTML> Thu, 27 Dec 2018 22:11:17 GMT vxs187 2018-12-27T22:11:17Z Unable to read GPIO pins. https://community.nxp.com/t5/LPC-Microcontrollers/Unable-to-read-GPIO-pins/m-p/835609#M33338 <HTML><HEAD></HEAD><BODY><P>I am not understanding how to read GPIO pins using the LPC 4370, I am unable to get the right reading.
