- Function: It can merge and package multiple binary files, such as bin files, font dot files, picture jpg, video avi, etc.
- Features: Files can be added, sorted, deleted, and offset addresses can be inserted to meet various FLASH burning requirements;
- Featured recommendation: You can save the list for easy secondary arrangement, saving the trouble of frequent adjustments in R&D!
- Applicable platform: Windows platform
- File size: 350K / single file / green version
Main interface:
Regarding the pre-offset: the offset address can be set freely, and whether to add file information is optional, as shown below:
If this option is selected, the merged file address and size information will be written to the leading offset address, each occupying 4 bytes, and the written data format is LSB->MSB, which is used to facilitate microcontroller index access.
The following example shows how to read jpg images for display by the microcontroller. We first package a series of jpg images into bin files and burn them into the FLASH chip under Ruiyou's RA8889. The microcontroller can read the address and size of the file at 8 bytes per time:
//获取图片的地址或者大小信息，共4个字节，再合并成一个数值返回
unsigned long Get_Picture_Address_Size(unsigned long flash_addr)
{
unsigned long temp;
unsigned short i;
unsigned int data_buffer[4]; //存放从FLASH读取出的数据
Enable_SFlash_SPI();
if(FLASH_BUS==0) SPIM_Select_Bus_0(); //总线BUS0
else SPIM_Select_Bus_1(); //总线BUS1
#ifdef OVER_128Mb
Select_nSS_drive_on_xnsfcs3(); //使用CS3位置的FLASH
#else
Select_nSS_drive_on_xnsfcs2(); //使用CS2位置的FLASH
#endif
RA8889_SPI_Flash_WREN(); //写入使能
nSS_Active();
delay_us(1);
SPI_Master_FIFO_Data_Put(0x03);
delay_us(1);
#ifdef OVER_128Mb //32bit 寻址
SPI_Master_FIFO_Data_Put(flash_addr>>24);
SPI_Master_FIFO_Data_Put(flash_addr>>16);
SPI_Master_FIFO_Data_Put(flash_addr>>8);
SPI_Master_FIFO_Data_Put(flash_addr);
#else //24bit 寻址
SPI_Master_FIFO_Data_Put(flash_addr>>16);
SPI_Master_FIFO_Data_Put(flash_addr>>8);
SPI_Master_FIFO_Data_Put(flash_addr);
#endif
for(i=0;i<4;i++)
{
data_buffer[i] = SPI_Master_FIFO_Data_Put(0xff);
}
temp = data_buffer[3]<<24;
temp += data_buffer[2]<<16;
temp += data_buffer[1]<<8;
temp += data_buffer[0];
nSS_Inactive();
while(RA8889_SPI_Flash_RDSR()& 0x01);
RA8889_SPI_Flash_WRDI();
Disable_SFlash_SPI();
return(temp);
}
After the microcontroller reads the jpg storage address and image size, it will be passed to RA8889 and displayed:
//从FLASH读取第n张图片出来显示
int Show_Picture(unsigned int pic_num)
{
unsigned long pic_addr, pic_size;
pic_addr = Get_Picture_Address_Size(0x0000+pic_num*8); //读取到第n个图片地址的值
pic_size = Get_Picture_Address_Size(0x0004+pic_num*8); //读取到第n个图片大小的值
SPI_NOR_initial_JPG_AVI (1,0,FLASH_BUS,FLASH_CS,1);
#ifdef OVER_128Mb
switch_24bits_to_32bits(FLASH_BUS,FLASH_CS);
IDEC_Select_SFI_32bit_Address();
#endif
JPG_NOR (pic_addr,pic_size,canvas_image_width,0,0);
return 1;
}
The special feature of this software is that it will save the compiled list in the .h file while packaging it into a bin file. You can read it back when you need it later, which is convenient for R&D and debugging! It saves frequent importing and adjusting the order of files, which can improve work efficiency!
The single-chip microcomputer needs to call for image display, and needs to call for jpg, avi and other image resources. Since the sizes of such files are different, if there is no FAT file system, it can only be made into fixed calls. It is inconvenient to change the image resources after subsequent production. By using this software, the file size and address information can be saved together while packaging the file. The single-chip microcomputer only needs to address according to the rules. For example, when using Ruiyou's RA8889, some users want to upgrade and change the image resources after mass production. This method can easily solve the problem!
