这里是部分源程序
上面是读取数据，下面是写入数据
- Continuous_Array_Read(adr_page_record,8,spi_buf,504);//读取504字节数据函数
- TestStatus Continuous_Array_Read(unsigned int PageAddr, unsigned int ByteAddr,
- unsigned char *DataBuffer,unsigned long ByteNum)
- {
- unsigned long i;
- if(ByteNum<=2162688)//СÓÚ 4096*528 Bytes
- {
- while(!(StatusRegisterRead()&0x80));
- SPI_CS_LOW();
- SPI_WriteByte(Continuous_Array_Read_Cmd);
- SPI_WriteByte((unsigned char)(PageAddr>>6));
- SPI_WriteByte((unsigned char)((PageAddr<<2)|(ByteAddr>>8)));
- SPI_WriteByte((unsigned char)ByteAddr);
- SPI_WriteByte(0x00); //
-
- for(i=0;i<ByteNum;i++)
- {
- DataBuffer[i] = SPI_ReadByte();
- }
- SPI_CS_HIGH();
-
- return PASSED;
- }
- return FAILED;
- }
- TestStatus DataToPage_ViaBuffer_WithErase_SecWay(unsigned char BufferNumber,unsigned int PageAddr,unsigned int ByteAddr,
- unsigned char *Data, unsigned int ByteNum)
- {
- unsigned int i;
- if((ByteNum<=(528-ByteAddr))&&(ByteNum>0))
- {
- while(!(StatusRegisterRead()&0x80));
- SPI_CS_LOW();
- switch(BufferNumber)
- {
- case 1: SPI_WriteByte(0x82);break;//
- case 2: SPI_WriteByte(0x85);break;//
- }
- SPI_WriteByte((unsigned char)( PageAddr>>6));
- SPI_WriteByte((unsigned char)((PageAddr<<2)|(ByteAddr>>8)));
- SPI_WriteByte((unsigned char) ByteAddr);
- for(i=0;i<ByteNum;i++)
- {
- SPI_WriteByte(Data[i]);
- }
- SPI_CS_HIGH();
- return PASSED;
- }
- return FAILED;
- }
