7inch Display + Get values from Arduino
Hello! i have this 7inch elecrow display connected to my Arduino Mega, and its also connected to a Barcode scanner, the scanner is saving the number in a variable, how can i make the Elecrow display a stored variable from an Arduino?
i would love to discuss HMI interface later when i get this "Display arduino variable on Elecrow Display" done, like how to make a GUI display the number in a nice font.

Hi EndoGraphic,
For this 7inch display, https://www.elecrow.com/esp32-display-7-inch-hmi-display-rgb-tft-lcd-touch-screen-support-lvgl.html
It can communicate with Arduino with I2C or UART port.
Hello @EndoGraphic
Please follow this tutorial series: https://www.youtube.com/playlist?list=PLwh4PlcPx2Ge-h-Pfsa7juFeWMgXmv8lc.
The Lesson5 is about making UI. We will update the course on how to communicate through UART in the future.
Thank you both! this was seriously helpful!
Schematic really helped me know what im doing, didn't know I2C was inherently different.
Tutorials has everything i need!
except for RTC usage, i will try to figure it out on my own but Can you help?
