<div class="markdown_content"><p>Hi<br/> I am about to configure ALL GPIOs on a Raspberry Pi 3 model B V1.2.<br/> It seems that I have limited understanding of why not all the IO’s become available with the corresponding mapped IO’s – the 'dwInUse' contains mapping of the inputs from GPIO0 to GPIO27. But 'dwInputs' are only showing GPIO0 to GPIO8 and GPIO15 as available inputs. These mentioned inputs work fine</p> <p>You will be able to watch the limited mapped IO activity here:<br/> <a href="https://drive.google.com/file/d/1zz4PBNBfRZBF2YkiJ2VQxw6L9MBVji7R/view?usp=sharing" rel="nofollow">https://drive.google.com/file/d/1zz4PBNBfRZBF2YkiJ2VQxw6L9MBVji7R/view?usp=sharing</a></p> <p>Can you please bring your best idea on why GPIO09 to GPIO14 and GPIO16 to GPIO27 state are not active (at a fixed zero state) in the dwInputs register?</p> <p>Thanks in advance.<br/> Best regards<br/> Andreas Bahrt</p></div>
