ArDMX + I2C display

Projects General Guidance
1

Hi all,

In a future project i'd like to be abled to read DMX values (so, as a receiver/slave, not as master) with a Arduino, using a MAX485 IC.

I've found the following code which seems to be very usefull:
https://playground.arduino.cc/DMX/Ardmx

But, as this device should be abled to change it's DMX startadress, i'd like to introduce a small OLED i2c display with a rotary potentiometer to set the start adress.
For example with this library: SSD1306Ascii

Is it possible to use these both together? Isn't there going to be any problems to the double serial usage (1 for reading DMX and 1 for communicating with the i2c protocol)?

I'd like to use a Arduino Nano for this by the way.

Looking forward to your replies!

I have not used the ArDMX code as I prefer to use a DMX library but you will be okay using an OLED display using I2C and DMX using Serial as long as you have enough RAM. The SSD1306Ascii library you linked to seems to be low RAM usage.
You will not be able to use Serial.print while using DMX though with the Nano. I have also used this Arduino Pro Mini clone with the DmxSerial library and you can have Serial.prints and DMX at the same time.
