问答

最近了解到了TCM，但不会使用想请教一下各位大佬该如何使用

哪位前辈有HK的RTC中断例程呢？求一份

华大的RTC电源应该怎么弄比较合适？

我在配置HC32F460的时钟，遇到了一个比较鬼畜的问题。我按照如下代码设置了时钟，但奇怪的是，我在硬件上端接晶振引脚，按说芯片会宕机才对，但芯片居然毫无影响，继续运行。想麻烦大家帮我看看，是我哪里设置的不对 [color=#d4d4d4][backcolor=rgb(30, 30, 30)][font=Menlo, Monaco, "][size=12px] [color=#569cd6]void[/color] [color=#dcdcaa]SystemClk_Init[/color]([color=#569cd6]void[/color]) { [color=#4ec9b0]stc_clk_sysclk_cfg_t[/color] [color=#9cdcfe]stcSysClkCfg[/color]; [color=#4ec9b0]stc_clk_xtal_cfg_t[/color] [color=#9cdcfe]stcXtalCfg[/color]; [color=#4ec9b0]stc_clk_mpll_cfg_t[/color] [color=#9cdcfe]stcMpllCfg[/color]; [color=#569cd6]MEM_ZERO_STRUCT[/color]([color=#9cdcfe]stcSysClkCfg[/color]); [color=#569cd6]MEM_ZERO_STRUCT[/color]([color=#9cdcfe]stcXtalCfg[/color]); [color=#569cd6]MEM_ZERO_STRUCT[/color]([color=#9cdcfe]stcMpllCfg[/color]); [color=#6a9955]/* Set bus clk div. */[/color] [color=#9cdcfe]stcSysClkCfg[/color].[color=#9cdcfe]enHclkDiv[/color] = [color=#4fc1ff]ClkSysclkDiv1[/color]; [color=#6a9955]// 168MHz[/color] [color=#9cdcfe]stcSysClkCfg[/color].[color=#9cdcfe]enExclkDiv[/color] = [color=#4fc1ff]ClkSysclkDiv2[/color]; [color=#6a9955]// 84MHz[/color] [color=#9cdcfe]stcSysClkCfg[/color].[color=#9cdcfe]enPclk0Div[/color] = [color=#4fc1ff]ClkSysclkDiv1[/color]; [color=#6a9955]// 168MHz[/color] [color=#9cdcfe]stcSysClkCfg[/color].[color=#9cdcfe]enPclk1Div[/color] = [color=#4fc1ff]ClkSysclkDiv2[/color]; [color=#6a9955]// 84MHz[/color] [color=#9cdcfe]stcSysClkCfg[/color].[color=#9cdcfe]enPclk2Div[/color] = [color=#4fc1ff]ClkSysclkDiv4[/color]; [color=#6a9955]// 42MHz[/color] [color=#9cdcfe]stcSysClkCfg[/color].[color=#9cdcfe]enPclk3Div[/color] = [color=#4fc1ff]ClkSysclkDiv4[/color]; [color=#6a9955]// 42MHz[/color] [color=#9cdcfe]stcSysClkCfg[/color].[color=#9cdcfe]enPclk4Div[/color] = [color=#4fc1ff]ClkSysclkDiv2[/color]; [color=#6a9955]// 84MHz[/color] [color=#dcdcaa]CLK_SysClkConfig[/color](&[color=#9cdcfe]stcSysClkCfg[/color]); [color=#6a9955]/* Switch system clock source to MPLL. */[/color] [color=#6a9955]/* Use Xtal as MPLL source. */[/color] [color=#9cdcfe]stcXtalCfg[/color].[color=#9cdcfe]enMode[/color] = [color=#4fc1ff]ClkXtalModeOsc[/color]; [color=#9cdcfe]stcXtalCfg[/color].[color=#9cdcfe]enDrv[/color] = [color=#4fc1ff]ClkXtalLowDrv[/color]; [color=#9cdcfe]stcXtalCfg[/color].[color=#9cdcfe]enFastStartup[/color] = [color=#4fc1ff]Disable[/color]; [color=#dcdcaa]CLK_XtalConfig[/color](&[color=#9cdcfe]stcXtalCfg[/color]); [color=#dcdcaa]CLK_XtalCmd[/color]([color=#4fc1ff]Enable[/color]); [color=#6a9955]/* MPLL config. */[/color] [color=#9cdcfe]stcMpllCfg[/color].[color=#9cdcfe]pllmDiv[/color] = [color=#b5cea8]1u[/color]; [color=#9cdcfe]stcMpllCfg[/color].[color=#9cdcfe]plln[/color] = [color=#b5cea8]42u[/color]; [color=#9cdcfe]stcMpllCfg[/color].[color=#9cdcfe]PllpDiv[/color] = [color=#b5cea8]2u[/color]; [color=#9cdcfe]stcMpllCfg[/color].[color=#9cdcfe]PllqDiv[/color] = [color=#b5cea8]2u[/color]; [color=#9cdcfe]stcMpllCfg[/color].[color=#9cdcfe]PllrDiv[/color] = [color=#b5cea8]2u[/color]; [color=#dcdcaa]CLK_SetPllSource[/color]([color=#4fc1ff]ClkPllSrcXTAL[/color]); [color=#dcdcaa]CLK_MpllConfig[/color](&[color=#9cdcfe]stcMpllCfg[/color]); [color=#6a9955]/* flash read wait cycle setting */[/color] [color=#dcdcaa]EFM_Unlock[/color](); [color=#dcdcaa]EFM_SetLatency[/color]([color=#569cd6]EFM_LATENCY_4[/color]); [color=#dcdcaa]EFM_Lock[/color](); [color=#6a9955]/* Enable MPLL. */[/color] [color=#dcdcaa]CLK_MpllCmd[/color]([color=#4fc1ff]Enable[/color]); [color=#6a9955]/* Wait MPLL ready. */[/color] [color=#c586c0]while[/color] ([color=#4fc1ff]Set[/color] != [color=#dcdcaa]CLK_GetFlagStatus[/color]([color=#4fc1ff]ClkFlagMPLLRdy[/color])) { } [color=#6a9955]/* Switch system clock source to MPLL. */[/color] [color=#dcdcaa]CLK_SetSysClkSource[/color]([color=#4fc1ff]ClkSysSrcXTAL[/color]); } [/size][/font][/backcolor][/color]

Nano130 M0 规格书里说芯片共有5个uart口，其中标准uart口两个uart0和uart1。还有三个uart是给Smart card用的，SC0_uart,SC1_uart和 SC2_uart，请问，我能把这三个Smart card用的uart用作通用的uart吗？如何设置？

新人，请问IGBT的NTC测量一般需要隔离吗？

求助各位大神，使用的是STM32F103C8T6这个片子，编写了一个程序ROdata=412,RWdata=76,ZIdata=17428,数据量应该是没有超出20K，可是程序运行出来的结果总是出错，如果把定义的变量顺序进行一些更改，例如原来顺序为：u16 a=?; u16 b=?; float c=?; s16 d=?;程序运行后的结果为e=?; 然后把顺序更改为float c=?;u16a=?;s16 d=?;u16 b=?;程序运行后的结果为e=?; 两次得出来的结果就不同，请教一下这是什么原因造成的？

使用的为F28027的开发板，现在在做一个外部中断的下程序，但是程序怎么就下载不进去，尝试新建了几个新的工程都不行，而原先的工程却可以正常下载。 我个人也写过不少C2000的程序，都从来没遇到过这样的问题。 所出现的提示为：wideinterrupt.out could not open file. 最近就要验收了，求指教。

WAKE_UP_RTC_MAX_TIME - 睡眠唤醒所需时间，根据不同睡眠类型取值可分为：睡眠模式/下电模式 - 65(默认) 这个单位是什么？ms？还是计数值？

有关RTC闹钟的中断,就是要求每一个小时整点产生一次RTC闹钟中断,前几个小时正常,可后面就不产生RTC中断,各位指点下.
