I recently replaced my original 2.8" LCD with a Nextion display.? The Nextion has a button battery slot on the back for RTC, and a micro SD card slot on the back for programming.? However, I noticed on the original LCD, there is an SD card slot on the back, but I've never seen anything mentioned about this?? Can the original LCD be programmed similarly like the Nextion displays and are there any examples of this?
