          Can you tell me the gpio wiring diagram

Moving this to new issue as OP keeps commenting on unrelated issues.

ESP8266 GPIO pinout is as follows: RST - To reset button with 3.3K pullup resistor. ADC - NC EN - 3.3V IO16 - MAX485 RE# and DE pin. (ensure correct logic level) IO14 - W5500 SCLK IO12 - W5500 MISO 1013 -W5500 MOSI VCC - 3.3V TXD - TX and MAX485 DI. (ensure correct logic level) RDX - RX and MAX485 RO. (ensure correct logic level) IO5 - W5500 RESET (ensure no clash with SPI) IO4 - WS2812B LEDs IO0 - Pulled to 3.3V with 3.3K resistor. IO2 - MAX485 (port 2) DI. (ensure correct logic level) IO15 - W5500 SCS (ensure no clash with SPI) GND - GND

Hope this helps.

Can you add two more dmx outputs？

MicroMarty commented 11 months ago

Are you using a buffer on gpio15, like that ? https://esp8266hints.wordpress.com/2018/02/13/adding-an-ethernet-port-to-your-esp-revisited/

Or did you use another method?

LoneWalkerWolf commented 11 months ago

@MicroMarty Yes, we're using a buffer. Pretty much exactly like the one you've linked.

We are working on this. Currently we are working on making a DMX splitter with a built in DMX node. We will let you know when we have added four DMX ports.

Looking at the code, it seems that IO0 is also connected to MAX485 (port 2) RE# and DE pin.
