[url=ictopic-2.html]#技术资源#[/url][size=4]新买了一块NI的USB接口采集卡（NI-6322），将其用于对多个传感器的信号采集，系统供电为多路输出直流电源（朝阳电源）。上电后发现采集卡有滋滋的响声，靠近听很明显，分析发现该声音频率在4KHz左右。[/size][size=4]请教大家，这是何原因呢？有解决方法吗？[/size] [size=4]谢谢！[/size]

我刚刚开始学习单片机MSPG2553去图书馆借了几本书，我在对照范例写代码时用到 _EINT(); 就出错，发出警报。 使用环境为 IAR EW430 5.3 发出警报为： Warning[Pe223]: function "_EINT" declared implicitly F:\msp430-launchpad\频率\main.c 17 Error[e46]: Undefined external "_EINT" referred in main ( F:\msp430-launchpad\频率\Debug\Obj\main.r43 ) 这什么情况 _ENIT 未定义？ 难道是头文件有缺失吗？ （头文件未更改） 我该如何解决这个错误？

[color=#222226]使用STM32F030F4P6做产品，[/color][color=#222226]现在是可以进入待机模式，使用RTC唤醒，然后能发送数据工作。[/color] [color=#222226]现在想让产品初始上电后先进入休眠，然后在RTC唤醒后，再发送数据；但是现在只要上电就直接发送数据，然后才进入休眠。[/color] [color=#222226]通过查看PWR->CSR寄存器，看到RM手册中说SBF和WUF位是可以用来判断是否从待机模式中醒来的，但是程序这么做了不起作用，还是上电就发送数据。[/color] [color=#222226]请各位大佬给看看可能因为什么导致的。[/color] [color=#222226]int main(void)[/color] [color=#222226]{[/color] [color=#222226] /* MCU Configuration--------------------------------------------------------*/[/color] [color=#222226] HAL_Init();[/color] [color=#222226] /* Configure the system clock */[/color] [color=#222226] SystemClock_Config();[/color] [color=#222226] [/color] [color=#222226] MX_GPIO_Init(); [/color] [color=#222226] MX_RTC_Init();[/color] [color=#222226] [/color] [color=#222226] RTC_AlarmConfig();[/color] [color=#222226] /* USER CODE BEGIN SysInit */[/color] [color=#222226] if (__HAL_PWR_GET_FLAG(PWR_FLAG_SB) != RESET ) //在此判断SBF标志位，若为1，则表明是被唤醒过[/color] [color=#222226] //if(__HAL_PWR_GET_FLAG(PWR_FLAG_WU)!= RESET)[/color] [color=#222226]{[/color] [color=#222226] __HAL_RCC_GPIOA_CLK_ENABLE();[/color] [color=#222226] MX_SPI1_Init();[/color] [color=#222226] Lora_init();[/color] [color=#222226] //HAL_Delay(10000);[/color] [color=#222226] Read_Ds18b20();[/color] [color=#222226] Lora_SendTemp1();[/color] [color=#222226] }[/color] [color=#222226] __HAL_RCC_PWR_CLK_ENABLE();[/color] [color=#222226] if (__HAL_PWR_GET_FLAG(PWR_FLAG_SB) != RESET)[/color] [color=#222226]{[/color] [color=#222226] __HAL_PWR_CLEAR_FLAG(PWR_FLAG_SB);[/color] [color=#222226] }[/color] [color=#222226] [/color] [color=#222226] HAL_PWR_DisableWakeUpPin(PWR_WAKEUP_PIN1);[/color] [color=#222226]if (__HAL_PWR_GET_FLAG(PWR_FLAG_WU) != RESET)[/color][img=0,24]https://img-bbs.csdn.net/upload/202005/26/1590486098_526184.png[/img] [color=#222226] HAL_PWR_EnterSTANDBYMode();[/color] [color=#222226] while (1)[/color] [color=#222226] {[/color] [color=#222226] [/color] [color=#222226] }[/color] [color=#222226]}[/color] [color=#222226]通过查看数据手册，说有2个标志位，一个是用来说明曾进入待机模式；另一个是曾被唤醒过，通过判断这个，认为设备进入过待机模式，那么就可以发送数据；若没进入过，那就先进入待机，不发数据。[/color] [color=#222226]这2个我都尝试了，没起作用，请大家指点。[/color]
