[Question] Touch not working after format NAND Flash

Ajtak

Hi,
I have DMT48270C043_06WT display.
I'm formatting NAND Flash, via 0x5AA5 command in config file. After formatting, the touch stopped working.

I'm tried System Clock Calibration, and upload new dataset, but touch not working. Same dataset, working correctly, before formatting.

The display works, but the touch does not.




How to fix it?

Thanks

Does your clock calibration follow the steps below?
1. Write 5AA5 to position 06 07 of CFG to open system time calibration
2. When inserting the card, connect the computer to the serial port and use the serial port tool 115200HEX to time for 30ms 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55
The attached file contains CFG that has been configured to open the system time calibration.

Yes, I'm Tried OSC Calibration, display shows Calibration successfully, but touch not working still.

After calibration, please test whether the communication is normal, send the 5A A5 04 83 000F 01 command, and check whether there is a return.

I tried send the 5A A5 04 83 000F 01 command, output is

1. OUTˇúˇó5A A5 04 83 00 0F 01 ˇő

How to change screen via UART? I think, touch not working after change screen.

DWIN-ARK

The attached file is the factory program of DMT48270C043_06WT, please download it to see if you can touch it

Ajtak

Factory program seems working corectly. I have problem probably vertical dataset. Exists some factory dataset, with vertical orientation? Thanks.

Ajtak

Is Vertical dataset?
Because see image.

DWIN-ARK

This is a vertical screen DEMO for DMT48270C043_06WT. You can download and test again.

Ajtak

Thanks, this vertical demo working correctly, I'll try to find out why my dataset isn't working after flashing and upgrade display.

Edit: Thanks, great support. I used config from your project in my dataset, and working all corectly very well . Thanks
