RTC clock issue

by conroyw on Sun Nov 08, 2020 2:47 pm

I have the Rev B cataloger shield with the Real Time Clock. The demo program for the SD card works fine. The demo program for the RTC doesn't work at all. I see the program loading up but no response from the board. I have the following configuration:


Arduino IDE 1.8.13 on a Mac running OS 10.15.7
Sketch name: pcf8523
I made no changes to the sketch.
Adafruit Metro board

Any suggestions?

@conroyw,

When you open the serial console at the default baudrate (57,600) do you see anything?

Can you post a photo of your wiring to the Metro.

It is not a Metro M0, correct? The wiring would be different if you had an M0 version of the Metro.

Thanks, I found issue. I had a bad usb cable. Different cable and it works fine.
