So, I've been programming arduinos (esp using usb serial, esp32 dev board, node mcu, uno) and yesterday when trying to connect on my windows machine i found that none of them will respond when plugged in via usb for programming) the esp doesn't even show more than a brief flash of the red led, the esp32 dev board, a brief flash of blue led.
After researching and trying a few things, including reinstalling arduino ide and usb drivers, nothing has changed (everything still dead).
Thinking something on my laptop maybe be hinky, I went to my desktop and unfortunately it's exactly the same.
Which leads me to think something in a recent update has messed something up on both machines.
Any ideas?
Try a different USB cable. Yours might be damaged or not able to provide enough current.
After my last win10 update, my arduino ide will not load. I downloaded the latest arduino-1.8.8-windows.exe. Executing the file, it told me to delete the version that was on my drive. I did so and then the arduino 1.8.8 was downloaded to my drive. When I executed the arduino file, the window popped up and the ide began to initialize and then began reading boards. it stopped and the arduino screen disappeared. Nothing else happened. I ran the troubleshooter and it told me there were incomplete files.
How do I get this ide to work correctly???
Please run the file arduino_debug.exe, which you will find in the Arduino IDE installation folder, from the command line, then copy and paste the full output in a reply here. Hopefully that will give us some information we can use to help you with the problem.
