### nandflash
由于公用数据线
Cubemx 启用Nandflash2， 无法设置参数
自己 bsp_nand， 重新设置参数初始化
控制 IO， 需要自己初始化
// IO : PB13 R/B, PG9 CE, PD4 PD5 PD11 PD12
static void HAL_NAND_MspInit_Control_IO(NAND_HandleTypeDef *hnand)
### Malloc
内存分配 FTL 可能用到
需要设置 LD

### FTL
直接整合到 nand Flash？
直接分配系统内存，就2-3k大小
### DMA2D启用
ARGB8888
### LTDC
只能选 RGB565
屏rgb888 16.7 兼容 rgb565
touch GT911
Cubemx 改不了hbp vbp 的值，需重新初始化去修改
每层的格式为 ARGB8888

基本参考正点原子，原子的hsw 这些的定义有些问题
### GT911 驱动
可以参考下野火的 ，有软件IIC 有硬件IIC。 但是野火的软件IIC 有点问题
硬件iic 可以设置一个值，让前端去轮询， 轮询到执行 Scan 获得坐标
可以参考
https://blog.csdn.net/weixin_38411122/article/details/129241223
https://github.com/oy2n/stm32cube-gt911-dma
touch 可以识别到触点了
### 字体 中文 图片
Display_char 有点问题
### nandFlash NorFlash USB虚拟U盘
spiFlash 分区， 配置写入分区
自己定义在FATFS目录下的文件， 没有被编译 需要改写 user 文件
#### FATFS 修改
1. FATFS/target 目录, 添加 nand_diskio.c nand_diskio.h
2. FATFS/APP/fatfs.h 引入 nand_diskio.h
3. FATFS.c MX_FATFS_Init 修改 引入驱动
引入flash Driver的定义
```C
uint8_t retUSER; /* Return value for USER */
char USERPath[4]; /* USER logical drive path */
FATFS USERFatFS; /* File system object for USER logical drive */
FIL USERFile; /* File object for USER */
```
头文件 extern 出去，供外部引用
在 MX_FATFS_Init 初始化
```C
void MX_FATFS_Init(void)
{
/*## FatFS: Link the SD driver ###########################*/
retSD = FATFS_LinkDriver(&SD_Driver, SDPath);
/*## FatFS: Link the USER driver ###########################*/
retUSER = FATFS_LinkDriver(&USER_Driver, USERPath);
}
```
FATFS_LinkDriver 来自 Middlewares/Third_Party/FatFs/ff_gen_drv.c
SDPATH UserPath 含有lun 信息, 即盘符 0: 1:
4. ffcong.h 磁盘数量定义
#define _VOLUMES 1
5. Middlewares/Third_Party/FatFs/
### 添加文件
```C
extern uint8_t retNAND; /* Return value for USER */
extern char NANDPath[4]; /* USER logical drive path */
extern FATFS NANDFatFS; /* File system object for USER logical drive */
extern FIL NANDFile; /* File object for USER */
```

前面调用 spiflash
```C
FATFS fs; /* FatFs文件系统对象 */
FIL fnew; /* 文件对象 */
FRESULT res_flash; /* 文件操作结果 */
UINT fnum; /* 文件成功读写数量 */
BYTE ReadBuffer[1024]={0}; /* 读缓冲区 */

#### USB 虚拟U盘的修改
/USB_DEVICE/App/usbd_storage_if.h
/USB_DEVICE/App/usbd_storage_if.c
HS FS
修改盘大小的参数， 读写盘的参数
MX_USB_DEVICE_Init()放任务中
spiFLASH 需要考虑总的扇区的偏离
nandflash 无需去考虑扇区的偏离
```C
#define STORAGE_LUN_NBR 2
#define SPIFLASH_BLK_NBR 0x1700 // 5888*4096 23M, 扣除7M 25M, 扣2M文件系统
#define SPIFLASH_BLK_SIZ 0x1000
#define NANDFLASH_BLK_NBR 0x800000 // 有效扇区？ 有效block 952*2048= 0x1DC000, *4 = 0x770000,
#define NANDFLASH_BLK_SIZ 0x0200 // page大小 0x800 2048 byte，还是Sector大小 512 0x200
```
以上 Flash 只有5.73M ，原因暂未查
