Hi folks, I just ordered my Spark Core and I’m very excited to give it a try. (Even though I have some basic education in electronics, I haven’t done anything in the last 6 years) So my first question refers to displays, specifically those displays with high quality like OLED. The thing is that I …

@JumpMaster , any chance you can share the HMI file? That bar graph is very cool and I really like your fonts!

I have ported the latest Arduino lib to Spark if anyone needs it.

I’m only using 3 Nextion commands so didn’t want to import the whole library. I’ll zip the images, fonts, and HMI file later and post a link. void nextionExecute() { Serial1.write(0xFF); Serial1.write(0xFF); Serial1.write(0xFF); } void setPic(const int page, const char* name, const in…

I have been playing with the nextion a bunch and it is quite easy to use. I have been able to implement a back button, keyboard with shift and cap lock, etc. Some of these have been put on the nextion forum. You can do a ton without any arduino code.

@LukeUSMC could you share with me ? I need it :)) many thanks.

@JumpMaster i liked your minimal approach and tested it out - but my text is not changing at all. i have the 2.4’’ Display on the Photons RX/TX. in setup() i did Serial1.begin(9600); and i try to execute: setText(0, "t0", "TEST!"); page 0 is the only page in my test and t0 the only object on th…

Hi @smnnekho , Try this even more basic example… setup() { Serial1.begin(9600); Serial1.write(0xFF); Serial1.write(0xFF); Serial1.write(0xFF); Serial1.write("t0.txt=\"test\""); Serial1.write(0xFF); Serial1.write(0xFF); Serial1.write(0xFF); } Also make sure the TX from the display is connected to t…

:flushed: :flushed: :flushed: :flushed: And there i am. Thought i would be the uberguy since it went so well with all that electronics stuff - i must be a genius. :stuck_out_tongue_closed_eyes: well not so much, since i connected RX --> RX and TX --> TX. Thanks for opening my eyes… it’s working …

Could I bug you for the HMI again? Also what size did you set the page to in PowerPoint so it wouldn’t get cropped when you imported it? Thanks!

Anyone got experience with >4 inch displays?
