New to Arduino but until today no problems. Have lilygo t display s3. Below is the file I have been working on, was running perfectly earlier, installed TFT_eWidget and I am now getting a communication error when I attempt to upload.
Screen is now blacked out so I know some communication has happened but received the following message and just cant figure out what has changed. I am sure its something simple.
"A serial exception error occurred: Write timeout
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.
For troubleshooting steps visit: Troubleshooting - ESP32 - — esptool.py latest documentation
Failed uploading: uploading error: exit status 1"
