HI,
My company recently purchased new stock of adafru.com/product/1947. However, when we attached the new ones to the MKR ZERO board and it didn't do anything other than turn on the backlight. When I use the Arduino UNO the projects run normally. So, I took a look and found that IOREF must be shorted with 3V pin. Nevertheless, it still no working.
When I used the version v. 2.3 the display worked!!! Additionally, I can not find a version number on the new display board.
I was wondering if this would be a hardware or software issue?
Thanks
