PICkit3/PICDEM PLUS在5V时产生过大电流错误

我已经从PIC18LF26K22移动到APIC18F26K22进行特殊的应用。我在PICDEM 16加板上使用旧的PACKIT3和XIDE的新版本。我已经将PICKit的配置设置为提供5.0V。我得到以下常见错误:“VDD上绘制的电流太多”“程序员对目标电源已启用-VDD=5.000000000伏。”在范围上没有看到任何下降,我以前用这种方式编写了各种5V图片。别以为我什么都忘了——这里只有新的东西是最新的IDE。我没有任何附属的董事会可以吸引权力。(3.3V编程工作良好)。我已经通过将辅助电源适配器连接到威廉希尔官方网站 板解决了这个问题,但是我很好奇这里发生了什么。

    I have moved from a PIC18LF26K22 to a PIC18F26K22 for a special application. I am using my old PICkit3 with the new version of X IDE on a PICDEM 16 Plus board. I have set the configuration for the PICKit to supply 5.0V. I get the common error below:
     "Too much current has been drawn on VDD"
      "Programmer to target power is enabled - VDD = 5.000000 volts."
Not seeing any drop on the scope and I have programmed various 5V pics this way before. Can't think that I forgot anything--only new thing here is the latest IDE. I do not have anything attached to the board that might draw power. (The 3.3V programming works fine).  I have addressed the problem by attaching the aux power adapter to the board but I am curious what is going on here.

Any ideas appreciated

看起来PicKit3正在努力避免吸烟。也许你可以从长凳电源给威廉希尔官方网站 板供电,并测量当前的抽签。

    It seems the PicKit3 is trying to save itself from smoking.
Maybe you could power the board from a bench supply and measure the current draw.
