看看是不是串口的时钟用的是内部RC，没有用到外部晶振。因为在工况等恶劣工作环境下，尤其是温度剧烈变化，内部RC会收到一定影响，从而降低了串口采样精度。所以一般用到串口通讯都要采用外部晶体作为时钟源
根据协议栈的函数，调试一下，看看有没有free mbox void netconn_free(struct netconn *conn) { LWIP_ASSERT("CB must be deallocated outside this function", conn->pcb.tcp == NULL); #if LWIP_NETCONN_FULLDUPLEX /* in fullduplex, netconn is drained here */ netconn_drain(conn); #endif /* LWIP_NETCONN_FULLDUPLEX */ LWIP_ASSERT("recvmbox must be deallocated before calling this function", !sys_mbox_valid(&conn->recvmbox)); #if LWIP_TCP LWIP_ASSERT("acceptmbox must be deallocated before calling this function", !sys_mbox_valid(&conn->acceptmbox));
这个中断是TIM2的CC1中断，不论电机是否工作，它都一直是enable的状态。电机在没启动的情况下，也是会发生HALL状态切换的，比如风扇电机顺逆风情况下
从手册上看，这两个外设都在AHB 高速总线上。DCMI 的速度很高，DMA2访问频繁，USB内部DMA再同时访问会可能会造成一定冲突。（DMA从响应到访问完成并不是一两个周期就能完成）。 楼主可否试试建立一定缓存，让传输分时完成试试。
没见过，不过之前看过一个这样的描述，调试器就像一个照相机可以记录一个时刻的CPU运行现场，j-trace好比一个录像可以记录CPU一段时间的运行记录。
先用烧录软件擦除或读写功能，看看连线是否有问题。 再用翻转对应的IO口看看点灯的那部分是否正常，刚开始上手一般都要试试翻转IO口
有专门水下用的：投入式压力变送器。 传感器因为是以大气位背景的“标压”，必须通过电缆中的一根通气管和水面相通就可以测量。 则会中电缆有专门买的，不用定做
不知道你的具体使用环境，我还是告诉你去哪里找参考吧。 ST有一个3D打印机的EVK，叫STEVAL-3DP001V1，里面用的是6个L6470H级联，L6470和L6480的通讯协议和控制部分基本相同，你可以参考这个开源的代码。 源代码地址在http://www.st.com/content/st_com/en/products/embedded-software/evaluation-tool-software/stsw-3dp001.html#get-software 怪事，原来是放在github上的，怎么现在要注册才能下载了。。。工程很大，你自己去下载吧。 在UM2076里面说了，stm32_cube\Drivers\BSP\STM32F4xx-3dPrinter\stm32f4xx_3dprinter_misc.c是步进驱动相关的代码 这个驱动的文件我拷贝在这给你悄悄，不够信息就要你自己去下载完整工程啦。 /** ****************************************************************************** * @file stm32f4xx_3dPrinter_motor.c * @author IPC Rennes * @version V1.0.0 * @date January 29, 2015 * @brief motor functions of 3D Printer BSP driver * (based on L6474) ****************************************************************************** * @attention * * © COPYRIGHT(c) 2015 STMicroelectronics * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * 1.
