Hi,
I’ve followed all the steps to install drivers, install arduino, download latest firsmware etc. However, when I try to upload firmware to the device, the arduino program decides to send to one com port higher than the one that is set in settings, and then complains that the device isn’t plugged in. This is consistent behaviour accross the last 3 usb port I tried plugging the device into.
Full readout for the upload looks like this:
Moderator edit to add code tags
Arduino: 1.8.9 (Windows Store 1.8.21.0) (Windows 10), Board: "SparkFun MaKey MaKey"
Sketch uses 8574 bytes (29%) of program storage space. Maximum is 28672 bytes.
Global variables use 593 bytes of dynamic memory.
Forcing reset using 1200bps open/close on port COM7
