  • 【相同的】一组数据 F103c8t6 与 L011D4P6 居然算出 不同的 CRC32

    【相同的】一组32位数据——114个——【相同的】CubeMX软件和IAR7.62编译环境。STM32F103C8T6与STM32L011D4P6芯片不同,他们算出来的CRC32校验数值居然不一样??——请问这,,,是怎么解决呢——??————两者都是同一台电脑的CubeMX图形化配置环境哦。。【用户代码就只有三行语句哦】。。uint32_tCRCValue;staticconstuint32_tdataBuffer[114]={0x00001021,0x20423063,0x408450a5,0x60c670e7,0x9129a14a,0xb16bc18c,0xd1ade1ce,0xf1ef1231,0x32732252,0x52b54294,0x72f762d6,0x93398318,0xa35ad3bd,0xc39cf3ff,0xe3de2462,0x34430420,0x64e674c7,0x44a45485,0xa56ab54b,0x85289509,0xf5cfc5ac,0xd58d3653,0x26721611,0x063076d7,0x569546b4,0xb75ba77a,0x97198738,0xf7dfe7fe,0xc7bc48c4,0x58e56886,0x78a70840,0x18612802,0xc9ccd9ed,0xe98ef9af,0x89489969,0xa90ab92b,0x4ad47ab7,0x6a961a71,0x0a503a33,0x2a12dbfd,0xfbbfeb9e,0x9b798b58,0xbb3bab1a,0x6ca67c87,0x5cc52c22,0x3c030c60,0x1c41edae,0xfd8fcdec,0xad2abd0b,0x8d689d49,0x7e976eb6,0x5ed54ef4,0x2e321e51,0x0e70ff9f,0xefbedfdd,0xcffcbf1b,0x9f598f78,0x918881a9,0xb1caa1eb,0xd10cc12d,0xe16f1080,0x00a130c2,0x20e35004,0x40257046,0x83b99398,0xa3fbb3da,0xc33dd31c,0xe37ff35e,0x129022f3,0x32d24235,0x52146277,0x7256b5ea,0x95a88589,0xf56ee54f,0xd52cc50d,0x34e224c3,0x04817466,0x64475424,0x4405a7db,0xb7fa8799,0xe75ff77e,0xc71dd73c,0x26d336f2,0x069116b0,0x76764615,0x5634d94c,0xc96df90e,0xe92f99c8,0xb98aa9ab,0x58444865,0x78066827,0x18c008e1,0x28a3cb7d,0xdb5ceb3f,0xfb1e8bf9,0x9bd8abbb,0x4a755a54,0x6a377a16,0x0af11ad0,0x2ab33a92,0xed0fdd6c,0xcd4dbdaa,0xad8b9de8,0x8dc97c26,0x5c644c45,0x3ca22c83,0x1ce00cc1,0xef1fff3e,0xdf7caf9b,0xbfba8fd9,0x9ff86e17,0x7e364e55,0x2e933eb2,0x0ed11ef0};CRCValue=HAL_CRC_C

  • BLE蓝牙:A厂家与B厂家 UUID配置完全一致、却不能互发数据 ?

    请问:BLE蓝牙:A厂家与B厂家UUID配置完全一致、蓝牙联机Connect可以但是却不能【互发数据】?俺是蓝牙模块的使用者,没工夫去仔细研发蓝牙。按理说:UUID配置一致应该可以互通哦。。。备注:模块双方【都没有设置密码】哦。。。
