I am new member and I need help
Hello. I want to make a custom dashboard for a project electric powered car using a nextion screen. Has anyone done anything like this before to tell me how easy is it? I have never used a nextion screen before or arduino but I'd like to learn starting from 0. I have gotten acquainted with the editor and watched many tutorials but I have some problems uploading the templates I want to the screen. Do I have to be using an arduino in order to upload the templates?
Thanks for your time.
You can upload directly to the Nextion screen using a Micro SD card or via a UART module.
You are trying to upload a file that ends in .hmi correct?
