Your ESP32 with display - cant upload first test

#1

I did the board manager, I installed the library too. I tried to upload the WIFI_Kit_32_FactoryTest file but I get errors.

I verified the USB drivers and they are fine, updated too.

I run WIN 10. I tried it on the mac, but the same problem.

50%+ of this kind of problems are related to the USB cable. Many many many of them are power only or otherwise not quite right.

Please try another cable, or this cable with a device for more than just power?

(And knowing this is the case I’ve still been caught by it. They look legit, but prove it to yourself and work with a known good one)

I tried 3 cables, yes they are data cables and work well with Teensy.

What next?
