[Zhengdian Atom STM32 Elite V2 Development Board Experience] Experience LVGL's SD NAND File System [Copy link]

Purpose

Verify the compatibility of SD NAND card on the Zhengdian Atom STM32 Elite V2 development board

Experimental Materials

• Zhengdian Atom STM32 Elite V2 Development Board

• TF card

• One SD NAND card

Experimental procedures

1. Open the routine [On-point Atom] Elite STM32F103 Development Board V2-Data Disk (Disk A)\4, Program Source Code\3, Extended Routine\4, LVGL Routine\LVGL Comprehensive Experiment (800x480)\Projects\MDK-ARM

2. Download to the development board after compilation

3. Copy the SD card files in the project into the card

SD NAND write speed:

TF card writing speed:

From this point of view, the writing speed of SD NAND card is much faster than that of TF card.

After inserting the card, the SD card was detected quickly and the access speed was quite fast.

This time, the 32Gbit card of Thunder Dragon CS Genesis SD NAND is used.

Popularize the difference between SD NAND card and TF card

edit

CS Genesis SD NAND cards have a very long write life and can be used as a good medium for data access or IAP.

Boss! That's great! I'll post a few more here in a few days!

This is good, it is designed mainly for SD NAND flash memory, which can be used as a storage device supporting read-only or read-write operations.

What LVGL is used by Zhengdian Atom? This interface looks good.

I have always wanted to learn LVGL routines. This routine is very good. I have learned it. Thanks for sharing!
