我是MPLAB X的第一次用户。我正在运行项目和构建错误，它们感觉像配置问题，但我不能确定它们是否与我安装的MPLAB X或我下载的示例项目有关。具体情况：构建平台：MPLAB X IDE V4.20与XC32 V2.05，运行在Mac OS高。目标：好奇心PIC32 MZ EF开发板（DM320104）。示例项目：“PIC32 MZ EF好奇WiFi RGB轻松配置”取自http://www. MICROCHEM.COM/…RoDuttDebug /D320104选项卡“附加资源”。当我将项目加载到MPLAB X时，它立即打印出一组451项目加载错误消息。它们都有相同的形式。前5个是：这不好。尽管如此，我还是尝试过“清洁与建设工程”。当然，它产生了大量的构建错误。所有这些都是在重新安装MPLAB X和工具之后发生的。第一次安装产生了相同的症状，但最初怀疑我做了一些定制，将其扔掉，也就是说，不要让安装更新路径变量。（找不到构建工具链吗？）这次，我基本上是默认的。主要问题是IDE或样例项目的配置有什么问题？第二个问题：我真正想要的是一个非常简单的“Hello World”项目来证明构建环境，例如闪存一个LED一秒钟。那是藏在别的地方的吗？ 以上来自于百度翻译 以下为原文 I'm a first-time user of MPLAB X.I'm running into project and build errors which feel like configuration problems, but I can't tell if they're with my install of MPLAB X or with the sample project I downloaded. Some specifics:Build platform:MPLAB X IDE v4.20 with XC32 v2.05, running on macOS High Sierra (10.13.5).Target:Curiosity PIC32 MZ EF Development Board (DM320104).Sample project: "PIC32MZ EF Curiosity WiFi RGB Easy Configuration" taken from http://www.microchip.com/...roductDetails/DM320104 tab "Additional Resource". When I load the project into MPLAB X, it immediately prints a set of 451 project loading error messages. They all have the same form. The first 5 are:Error: Project "wifi_rgb_easy_configuration" refers to file "gzlog.h" which does not exist in the disk. The project failed to load.Error: Project "wifi_rgb_easy_configuration" refers to file "crc32.h" which does not exist in the disk. The project failed to load.Error: Project "wifi_rgb_easy_configuers to file "deflate.h" which does not exist in the disk. The project failed to load.Error: Project "wifi_rgb_easy_configuration" refers to file "inffast.h" which does not exist in the disk. The project failed to load.Error: Project "wifi_rgb_easy_configuration" refers to file "inffixed.h" which does not exist in the disk. The project failed to load.This can't be good.Nevertheless, I tried "Clean and Build Project".Of course, it produced a flock of build errors. All this happened after re-installing MPLAB X and tools.The first install produced the same symptoms, but initially suspected I had done some customization that threw it off, i.e., don't let the install update the PATH variable. (Failure to find the build toolchains?) This time, I basically went with defaults. The principal question is: what's wrong with the config for the IDE or sample project? A second question: What I really wanted was in essence a really simple "Hello world" project to prove the build environment, e.g., flash a single LED once second. Is that hidden someplace else?

限位状态，查看AXISSTATUS确认；（2）电机控制模式不对，INVERT_STEP设置为相应的脉冲模式（双脉冲或脉冲+方向）；（3）电机接线问题，确认接线。2.DPOS和MPOS极性相反，或电机转向与预期相反，解决办法：修改电机的极性，通过INVERT_STEP指令或驱动器软件修改。
