Open oopsitsaflame opened 6 years ago

Hi, is there a wiring howto? i am having trouble getting my nextion (3.5inch but thats another story) connected. Which ports on RAMPS board?

weeelfi commented 6 years ago

For RAMPS: The pins on Aux-4 is D16 and D17

External supply of 5V is needed. Nextion needs 450mA

And finally, you need to change serial 3 to serial 2 in \ITEADLIB_Arduino_Nextion\NexConfig.h (line 37)
