Arduino MKR 1010 Upload failure

[julesmoretti]

Hello:

When trying to upload the HX711/HX711_basic_example.ino to the Arduino MKR 1010

I get:

Sketch uses 13136 bytes (5%) of program storage space. Maximum is 262144 bytes.
Global variables use 3012 bytes (9%) of dynamic memory, leaving 29756 bytes for local variables. Maximum is 32768 bytes.
