How to upgrade and correct the screen

请认真阅读刷卡时的注意事项，非正常操作可能会导致刷卡异常

Please carefully read the precautions when swiping the card, abnormal operation may lead to abnormal swiping.

一.SD卡的准备

  根据不同的条件，客户可自行采购SD卡或者在我们的小程序上申请SD卡，如果通过小程序申请的卡，里面是自带程序的，直接看如何刷屏即可

I. Preparation of SD card

According to different conditions, customers can purchase an SD card by themselves or apply for an SD card on our applet. If the card applied through the applet comes with its own program, just look at how to swipe the screen directly.

1.1 SD卡的准备，请务必使用16G以下的卡，不同显示屏使用的卡不同，如图所示

1.1 To prepare the SD card, please be sure to use a card below 16G. Different display screens use different cards, as shown in the figure.

1.2 卡格式化：通过读卡器连接到电脑后，右键进行卡格式化，请注意，在格式化选择中，使用分配单元大小为4096字节，请勿使用快速格式化

1.2 card formatting: after connecting to the computer through the card reader, right-click to format the card. Please note that in the format selection, the size of the allocation unit used is 4096 bytes, so please do not use quick format.

1.3程序的获取：如图拍摄任意一个地方的编码，发技术群内即可获取匹配的程序（如果你在小程序申请，请把此处的编码在申请提交时备注一下）

1.3 program acquisition: shoot the code in any place as shown in the figure, and you can get the matching program in the technical group (if you apply for a small program, please note the code here when submitting the application).

1.4把解压后的整个DWIN_SET文件夹（亦可能为其他命名的文件夹）放入内存卡中（相关程序包请向我司询问）

1.4 Put the whole decompressed DWIN_SET folder (or other named folders) into the memory card (please ask our company for related packages).

二.屏幕的刷屏流程

2.1 把带有程序的SD卡在系统断电的状态下插入屏幕的卡槽，上电等待自动刷包，当第二行尾部出现END，断电

2.2 继续上电，等待第一行出现2023.06.30数值，然后等待第二行出现END

2.3断电拔卡即可，大概整个过程需要10分钟，等待即可

（务必完成2.2的操作，刷机才算完成，可以多刷几次）

II. The screen brushing process

2.1 Insert the SD card with the program into the card slot of the screen when the system is powered off, power on and wait for automatic package brushing. When the END appears at the end of the second line, power off.

2.2 Continue to power on, wait for the value of June 30th, 2023 to appear in the first line, and then wait for the END to appear in the second line.

2.3 power off and pull out the card, and the whole process will take about 10 minutes, just wait.

(Be sure to complete the operation in 2.2, and the brushing is complete. You can brush it several times more.)

注意：如果每一行后面都是000，则说明卡失效或者程序失效，需要重新刷屏！

Note: If each line is followed by 000, it means that the card or program is invalid and needs to be refreshed!

三.屏幕的矫正

在刷屏后出现点击不了的情况，但是显示已经正常，可以通过刷矫正文件程序处理，在SD卡中放入矫正文件（文件请于技术群问询，参照以上的流程一SD卡的准备），通过依次点击十字星，共5次后，断电拔卡即可。

III. Screen correction

After the screen is swiped, you can't click, but the display is normal. You can brush the correction file program, put the correction file in the SD card (please consult the technical group for the file, refer to the above process to prepare an SD card), click the cross star in turn, and after a total of 5 times, power off and pull the card.
