首先在进行FLASH寄存器的写操作之前我们同样需要对Flash进行解锁,之后只需要调用HAL_FLASH_Program 传入需要写的数据位数的类型,写入的FLASH地址和数据即可。 需要注意的是在调用F1的hal库的时候我发现F1的这个函数是支持写入double类型的参数的,与此同时F1中的写入FLASH_TYPEPROGRAMDATA_BYTE的这个参数是消失了的。 而L...
if (HAL_FLASH_Program(FLASH_TYPEPROGRAM_BYTE, (uint32_t)address, *data) == HAL_OK) 注意我是以8位数据写入的,因此第一个参数写入的byte ,如果要想写入32位的数据,改为对应的参数就行了。 { address = address + 1; data=data+1; } else { /*дÈë³ö´í£¬·µ»...
写入位置,每次+8是因为存储的类型是uint64_t,占用64bit,8字节for(inti =0; i < len;i ++ , startAddressIndex +=8) {//写入数据HAL_FLASH_Program(FLASH_TYPEPROGRAM_WORD, startAddressIndex, data[i]);
if (HAL_FLASH_Program(FLASH_TYPEPROGRAM_BYTE, (uint32_t)address, *data) == HAL_OK)注意我是以8位数据写⼊的，因此第⼀个参数写⼊的byte ，如果要想写⼊32位的数据，改为对应的参数就⾏了。{ address = address + 1;data=data+1;} else { /*дÈë³ö´í£¬·µ...
Hi Akos, When I use the below function, it writes the bytes in the correct flash address, however bytes are written in LSB HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, flash_ptr, data) e.g.: when I write 0x0A1B2C3D4C5E6F55 I see that ...
