void SectorErase(void) { *(FlashStart + 0x5555) = 0xAAAA; *(FlashStart + 0x2AAA) = 0x5555; *(FlashStart + 0x5555) = 0x8080; *(FlashStart + 0x5555) = 0xAAAA; *(FlashStart + 0x2AAA) = 0x5555; (FlashStart + SectorSize4) = 0x3030; DINT; DELAY_US(40000); EINT; }改写成擦除0x200000到0x200005的代码

这段代码可以改写成擦除特定的Flash地址范围的代码，具体实现如下：

void flash_erase_range(uint32_t start_address, uint32_t end_address) {
    uint32_t flash_address = start_address;
    while (flash_address <= end_address) {
        volatile uint16_t *flash = (volatile uint16_t *)flash_address;
        flash[0x5555] = 0xAAAA;
        flash[0x2AAA] = 0x5555;
        flash[0x5555] = 0x8080;
        flash[0x5555] = 0xAAAA;
        flash[0x2AAA] = 0x5555;
        flash[0x0000] = 0x3030;
        __disable_irq();
        delay_us(40000);
        __enable_irq();
        flash_address += SectorSize;
    }
}

// 擦除0x200000到0x200005
void erase_flash_range() {
    uint32_t start_address = 0x200000;
    uint32_t end_address = 0x200005;
    flash_erase_range(start_address, end_address);
}

其中，`flash_erase_range`函数用于擦除特定的Flash地址范围，需要传入起始地址和结束地址，然后循环擦除每个扇区。`erase_flash_range`函数用于擦除0x200000到0x200005这个特定的Flash地址范围，直接调用`flash_erase_range`函数即可。
