I have arduino uno wifi, dmx output too. When i had arduino uno 3 it was working. Now i can upload library but when i connect max485 with dmx out put plug into light, there is no connection. My light has small dmx light at the side which is showing dmx connected.
When i connect a and b and touch around the max485 with cable dmx activating for a while. When i put properly not connected
Please show your schematic.
PS Uno Wifi at general is a bad choice for beginner.
Are you using an Uno WiFi or an Uno WiFi Rev2?
UNO R3 WiFi ATmega328P + ESP8266
Copied from item description..
Between even dont connect arduino and breadboard it is working only with max485
