我试图用STM32L4硬件模块生成CRC.我想验证fatfs文件,所以基本上我有字节数组.我正在使用这个CRC 生成器.

不幸的是我无法弄清楚如何设置STM32L4来生成相同的结果.我需要CRC32而且我有

组态:

hcrc.Instance = CRC;

/* The default polynomial is not used. It is required to defined it in CrcHandle.Init.GeneratingPolynomial*/
hcrc.Init.DefaultPolynomialUse    = DEFAULT_POLYNOMIAL_DISABLE;
/* Set the value of the polynomial */
hcrc.Init.GeneratingPolynomial    = 0x4C11DB7;
//hcrc.Init.GeneratingPolynomial    = 0xFB3EE248;
hcrc.Init.CRCLength= CRC_POLYLENGTH_32B;
/* The default init value is used */
/* The default init value is not used */
hcrc.Init.DefaultInitValueUse     = DEFAULT_INIT_VALUE_ENABLE;

/* User init value is used instead */
//hcrc.Init.InitValue               = 0;
hcrc.Init.InputDataInversionMode = CRC_INPUTDATA_INVERSION_NONE;
//hcrc.Init.InputDataInversionMode = CRC_INPUTDATA_INVERSION_BYTE;
