Howdy.
I started here: https://learn.sparkfun.com/tutorials/ge … for-teensy, bought all the items I needed, including the 32x64 LED, the SmartLED Shield for Teensy, and the Teensy(3.6). Followed the guide step-by-step(thanks for the detailed guide). I had the first example: “Feature Demo!” running correctly. I moved to the example: “Matrix Clock w/ the DS1307 RTC Module”, again step-by-step. I have the “set time” step returning the correct time in the serial monitor. When I adjust the SDA and SCL wires as shown and load the “Matrix Clock” example, the display returns “No clock”. I’ve fiddled about with repeat wiring and reverse wiring but always with the same result. Also unplugging the USB and power supply for a cold start has the same result. I went back the the middle of the page and started over- same thing.
Did I miss something totally obvious?
Thanks.
