i would like something like this with just a diode…
i don’t know what i’m doing wrong … 
Try connecting the output of the flip flop to the upd of the clear display
You only update the display on boot. Add a 2nd wire to the concat output and run it to a pulse-on-change node, then wire pulse-on-change to the any node. That should clear & update the display when text changes.
I have one more question? how can i type shapes or logotype?
Using the “line”, “rectangle”, etc. nodes.
Thanks for all the above info. I really appreciate.
I’m using Amica NodeMCU esp8266 board. What changes that I should do? there are no A4 & A5 pin on the board…
What else should I change?
thanks.
I don’t know what you’re trying to do, but it would be better if you start a new thread with the particular query about your project
in NodeMCU only A0 analog
I’m referring to the same issue IIC I2C OLED Display but this time with ESP8266 NodeMCU board (instead of Arduino).
With only A0 analog pin, how to connect OLED display with the board? What other changes that I should observe in implementing all the above suggestions (for Arduino) on NodeMCU board?
Not sure, but try this
To define the ports in XOD for NodeMCU, it is D1 will not be D1 but D5 and D2 will be D4
Summing up in XOD use D5 for SCL and D4 for SDA (you should not define them, but they will be used by i2c)
On the board connect SCL to D1 (GPIO5) and SDA to D2 (GPIO4)

gweimer do you maybe know why there is no Digispark support and I can’t even upload in code via Arduino IDE? I’m constantly getting some error.thanks!
Sorry, I just use UNO and don’t understand much about hardware support. But if it doesn’t work in IDE, it’s almost certainly not going to work in XOD.
works in IDE … ok thanks anyway
The instructions for digispark mentions that it needs to be manually added to IDE. Did you do this for XOD? There are instructions in XOD documentation for adding new boards to XOD.
ok, where does it say in xod … i haven’t seen it
