【开源】对迪文屏的数据文件实现在线升级的一种方法
背景：目前迪文屏升级一共有两种方式：插卡和上位机通过串口升级，两者不足之处有 ：1、批量生产升级效率慢且繁琐(当升级时，每个设备需要单独去插卡或者用电脑上位机升级) ，并且增加了人工成本。2、自己的项目中无法实现对迪文屏在线升级(当产品已发出需要修复BUG时，无法在线修复)。3、无法判断新老版本(当数据文件没有变化时执行了重复升级)。
设计：
基于以上不足，通过在自己的项目中嵌套一种方法实现对迪文屏数据文件的升级，弥补以上的不足。

感谢楼主分享，赞一个 非常不错，顶一个！ 感谢楼主分享 感谢楼主分享 后续测试发现有丢数据的现象，原因在于写的时候没有延时，因此需要改动一下
writeDgusRam_ByAddr(DGUS_USER_RAM_ADDR,(uint8_t *)readBuff,sizeof(readBuff));
writeDgussFlash_ByAddr(DGUS_USER_RAM_ADDR,addrTo32KBytes,50);
Dgus_Dealyms(50);这几段代码改成这样就好了 其实最严谨的做法应该把已经写入迪文屏外部flash中的数据以32K BYTE为单位再读回来与写入的数据做一下比较或者开启CRC校验，但是这样会影响会影响升级的速度 helloworld 发表于 2022-7-18 10:04
