您好 按您的写法 我做了一个打印如下：void printArray(SDK_U8Array512Type array){ SDK_SHOWLOG(SDK_LOG_LV_INFO, "enter function printArray: \n"); unsigned char str[80]; for(int i=0;i10;i++) { //snprintf(&str[i], 1, "%x", array[i]); //snprintf(str, 1, "%s", "="); snprintf(&str[i], 1, "="); } SDK_SHOWLOG(SDK_LOG_LV_INFO, str); SDK_SHOWLOG(SDK_LOG_LV_INFO, "\n");}void Gp1Task0(void){ SDK_SHOWLOG(SDK_LOG_LV_INFO, "enter function Gp1Task0: \n"); uint8 breakSignal = 0; g_timesCountGp1Task0++; if (g_timesCountGp1Task0 % RUN_PER_100MS == 0) { SDK_SHOWLOG(SDK_LOG_LV_INFO, "enter function Gp1Task0 --> RUN_PER_100MS: \n"); //该接口读到的数据是抽象层返回的以50ms周期轮询Host发来的数据 SDK_ReadHostData(g_gp1DataFromHost); printArray(g_gp1DataFromHost); //0xAA if (g_gp1DataFromHost[0] == FIRST_FLAG_DATA) { SDK_SHOWLOG(SDK_LOG_LV_INFO, "enter FIRST_FLAG_DATA 0xAA before SDK_SendHostData\n"); SDK_SendHostData(g_gp1DataFromHost); SDK_SHOWLOG(SDK_LOG_LV_INFO, "enter FIRST_FLAG_DATA 0xAA after SDK_SendHostData\n"); } } //每10ms检查一次 if (g_timesCountGp1Task0 % RUN_PER_10MS == 0) { SDK_SHOWLOG(SDK_LOG_LV_INFO, "enter function Gp1Task0 --> RUN_PER_10MS: \n"); if (g_faultSignal == 1) { breakSignal = 1; } g_canBrakeMsg.data[0] = breakSignal; SDK_CanTransmit(SDK_CAN_CHL00, &g_canBrakeMsg); }}在日志中还是没有看到相应的输出内容：不太清楚华为内部的打印方法，我看网上的例子就是这样写的，所以参考写了一下，麻烦看下，另外为什么总有一个右中括号呢？我的文件里从来没有打印过谢谢
