https://devzone.nordicsemi.com/f/nordic-q-a/46912/rs485-transmit-enableWe&#39;re running a multi-drop single duplex RS485 bus, so it&#39;s important to stop driving the bus as soon as a transmit is complete so the next device can transmit without two drivers driving the bus at once. Is there a way to set up hardware control of theen-USTelligent Community 13Sat, 04 May 2019 11:10:38 GMThttps://devzone.nordicsemi.com/thread/185287?ContentTypeID=1Sat, 04 May 2019 11:10:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:03c68f6d-429d-44ae-8474-14d9f7097a4eawneil<p>See also the duplicate thread:</p> <p><a href="https://devzone.nordicsemi.com/f/nordic-q-a/46911/rs485-transmit-enable">https://devzone.nordicsemi.com/f/nordic-q-a/46911/rs485-transmit-enable</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/185264?ContentTypeID=1Sat, 04 May 2019 00:38:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:efaabc96-c1a4-4985-98d1-9cc097ff71c2icanhazscreenid<p>I&#39;m sure there is a more elegant way of handling this situation but I typically configure the &quot;driver&quot; pins as inputs in this case. Set them up as inputs, change them to outputs before transmitting, then set them back to inputs when transmission is complete.</p><div style="clear:both;"></div>
