T56编程器ICSP读写PIC单片机过流，不接目标板也过流，自检又是正常的

佳维

T56编程器ICSP读写PIC单片机过流，不接目标板也过流，电流调最大（目标板工作电流10ma）也是过流，去掉勾选vcc enable也会过流（偶尔能正常，外接供电能正常读写），试过12.78后所有版本现象均一样，编程器自检又是正常的，24年6月购买后固件已首次更新，现有版本软件固件更新均为灰色，已求解决方案

When you connect the T56, look to arrow in the picture for the fw version, please post it, and the voltage you see displayed.
Also post were you get the messages for overcurrent, and version of software you use now.
Also, please post the IC were you see the problem, just to try the same here.

   Rgds

空编程器都报短路，开关vcc都会报，固件1.73，12.66等老版本软件会提示硬件固件不支持，usb电压4.94V，换电脑换USB线均没有用，偶尔能关vcc才能目标板外接电源读写，如实拍视频截图（手机上传可能有重复）[attach]2438[/attach]

每次烧录要花费很长的时间，半天难得碰到一次正常，急求解决方案，谢谢

以上视频12.78--13.10所有版本均已测试，ICSP过流报警不能操作的情况一样

   Hello,           Based in what you wrote, several machines tried, several firmware loaded correctly, and my tests with my own T56,
it seem that you may have a faulty component in the ICSP area, a leak, but not a short/open circuit, as that will show in the test.
An example of a short/open circuit, and an area, you can see here Help me probleme t56 eror G-j1 - XGecu T56 使用问题解答 - XGecu Programmer Forums - Powered by Discuz! , just to show the area, and if the unit isn't on warranty.
T56  is also a bit sensitive to ground noise from machines with poorly designed power supply's, and i prefer to use it on USB3 ports. In the T76, they improve it a lot, at least my findings so far, and they have available better protected adapters for the job.
You can also try, contact the point of purchase, many times they help to get parts, and info, when needed.
If not tried yet, you may get extra help from their support at Contact US , as many times they are 'absent' from this forum.
Please, if any development you may have, post here, please, as it may help others.

感谢您的回复，事实上我并不知道T56保修期多长时间，以下是我淘宝购买的订单详情，初次使用时是12.78版软件并执行过固件更新，因春节假期并未修身携带T56编程器，复工后将按照您的指示检查一下，事实上我的编程器自检提示并没有故障，连接编程器反复重新安装软件目录中的驱动程序偶尔又能正常使用（win10官网原版22H2），但拔除后再插入/重启软件后ICSP又是无止境的过流，zif正常提示引脚接触不良，且均为空编程器，不排除是否为固件问题，但当前所有版本支持软件均无法再次固件更新（功能菜单为灰色），购买后平时只是使用zif座读写IC，初次使用ICSP就碰到这个问题，软件是否能开放固件更新以确认一下，急求解决，谢谢！

   另外补充一下我的疑问：为什么win10任务栏usb设备右键菜单中会出现弹出T56编程器选项，我用过的所有编程器几乎都不会以类似USB存储设备形式弹出编程器的选项，这个感觉有点奇特

   As i know, if you have a problem with the ZIF socket, just order a new one , and replace it, as the Zif is installed in a socket by itself... Please see link below, you do not even need to open the T56 :) but be careful a lot if you decide to it, and it's cheap. The initial kit from XGECU also bring the socket, just in case of damage/other reason. Warranty, i think, is one year, and yours T56 is out. You can also ask the dealer that sold you the unit.

   可能您误解了我的意思，PIC单片机读写界面有zif座和ICSP两种方式，zif座并不存在问题，我描述的情景是：编程器不放置任何任何器件ICSP_8Pin插座也未连接任何导线，选择zif座读写时提示正常的引脚接触提醒，选择ICSP不管是否开启vcc enable读写操作均提示过流（重申一下，编程器除了USB线缆外没有任何外部器件连接），编程器自检显示自检正常，个人感觉应该不是硬件IO口的推挽三极管问题，尝试不同电脑/重装各版本软件/重新安装驱动均无改善，修改源码烧录验证烧录过程浪费很长时间（正常概率非常低1%以下，偶尔正常的时候ICSP空编程器提示器件ID不符，连接ICSP准备正常操作后又是无尽止的过流，哪怕关闭vcc_enable使用目标板供电），结合您前面给出的意见，申请软件集成开放固件更新功能便于修正这种奇怪的问题，谢谢！

   现在编程器不在身边，就文字描述一下，为了更方便的阐述，T56编程器插入同时插入一个U盘，会在桌面右下角任务栏出现一个U盘图标，右键点击该图标，会出现弹出T56编程器的选项和弹出U盘的选项，您方便的话可以验证一下，这一点会产生驱动类型识别错误的错觉，因为其它的USB接口非存储设备（如ch34x，ft232，USB摄像头等）均不会出现在这里。

   Hello, I think it depends of driver version used by the installer. .
Here tested:
Coright SKYPRO I, and it do not show to eject.
Xgecu T56 and T76, and SVOD4, all show to eject.

   能否在下次软件更新中激活"固件更新"菜单以修复这类奇怪的问题？我曾联系过淘宝商家，他说SPI 25flash烧录也经常出现过流提示，应该不是个例，请予以重视并给出解决方案，谢谢！

Hello again,
                  If you suspect that firmware is the culprit because it fail to load correctly, you
have two choices.
1-just wait that a new firmware, newer then the one already installed and identified by the Xgecu app, is available
   and it will, hopefully, show the flash enable, because newer version available. This happen often to add new features
   or correct bugs.
2-If firmware need to reload the present version, due to a failure loading it, or programmer not recognized at all, you may need to start an emergency firmware reload. You can see the procedure here Programmer not recognized after firmware update failed - T56/TL866II Plus新增芯片支持 - XGecu Programmer Forums - Powered by Discuz!

Overcurrent warnings from real use, are different from eventual bugs with no current load at all.  Current max level at T56 and app version 13.10, is 350mA, but to inform you, with T76 and app 13.11 is 400mA. If the 350mA current limit from T56, is 'real' safe max level, i expect to see Xgecu app, help users informing that alternate power feed is needed, and how to do it correctly/safely, or remove those ICs from support list :'( , as T56 is a discontinued product, it will, hopefully, have updates for some years, but that will reach an end. I'm expecting that will happen to programmer TL-866II sooner/later. Also, unfortunately, Xgecu manufacturer, did not timely update available information at it's site Haikou Xingong Electronic Co,Ltd as still show T56 in production, and that is, as i know, not correct, and even the 'blue prints' for T76 happen the same.

That is my personal opinion, but the risk is yours. Proceed, always, with care. Hopefully ADMIN will help you.
For sure, Xgecu products are great value for money, but not error free, as you can see with updates, they are always trying to improve :)

Let us know, please, any development you may have.

Thank You
