修改了以下几处错误：

1. 在函数中使用 `memset()` 函数，但未包含 `<string.h>` 头文件，导致编译器无法识别 `memset()` 函数。需要添加 `#include <string.h>` 头文件。

2. 在 `oled.h` 和 `password.h` 中都定义了 `F6x8`、`F8X16` 和 `Hzk` 等变量，导致链接时出现重复定义的错误。可以将这些变量的定义放在单独的 `.c` 文件中，并在对应的 `.h` 文件中声明它们。

3. 在 `oled.h` 中使用了 `uint8_t` 类型，但未包含 `<stdint.h>` 头文件，导致编译器无法识别 `uint8_t` 类型。需要添加 `#include <stdint.h>` 头文件。
