Hi all
thank you for helping me, my issue is resolved because of you all suggestion.
but I am beginner in the Arduino. i am doing one project using Atmega4809 and Nextion display. for Nextion display already i created the GUI (HMI File). in this GUI 32 pages is there and now I want to communicate this display with the atmega4809. but I am getting stuck because I am not getting idea i am writing right or wrong code . so please help me in this.
problem:- 1). in GUI I have 32 pages and on every page I use system mode and fan mode. fan mode will be off or on and in system mode- off, cool, heat, cruise control, emergency heat, dehumidify and humidify but in system mode one will be selected at one time and same for fan mode. and also if i will change these from any page then it will be change in every page.(i already shared the screenshot and I used dual state buttons)
2). I used left side button for opening the pages - home, temp, hum, co2, outdoor air temp, setup.
I want to write the Arduino code for this
functionality so can anyone write the code for this functionality then I will get the idea and I can complete my project for all GUI.
Hi @manishsingh9752. Are you offering to pay someone to do this work for you?
The reason I ask is because there is a "Jobs and Paid Consultancy" forum category specifically for offering paid work. If you are offering payment then I would move your topic there to ensure the people who are interested in such opportunities will see it.
The category you have posted in is generally used to request free assistance in accomplishing your project. The helpers in this category are happy to help you learn, but not often interested in doing your project for you.
actually I don't want assistance only i want some guidance if anyone can guide then I can move forward in my project because i want to do it from myself but i have need of guidance only.
Of course you can share your code but it is preferred by most people that you do so directly in the forum, not as an attachment. Don't forget the <code/> tags.
The 4809 has 3 hardware serial ports you can use for communication with the Nexion. There is no reason to use Software Serial.
Most simple would be to use Serial1 on Rx and Tx if you were using a Nano Every, but it's not clear what pins you are using for what purposes on the custom circuit board and which of the three serial ports would be best to use.
