I recently purchased the Adafruit Grand Central and I am having issues with the Upload via the Arduino IDE. Sometimes the upload is successfully and sometimes I get errors with the same sketch. The upload also takes like forever. I have already tried different and simple sketches, doesn't change the problem. Also I have tried different computers.
The following error apppears at Output:
Code: Select all
Sketch uses 16952 bytes (1%) of program storage space. Maximum is 1032192 bytes.
Performing 1200-bps touch reset on serial port COM7

Thank you all in advance
