### 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
|

直接分配系统内存，就2-3k大小

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

### 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 */
|
|
```

#### 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
