I was almost out of memory on the teensy 3.2 so i grabbed a teensy 3.6 ( two actually)…
Once mounted on the matrix shield ( plugs into the shield with female headers so i can swap between teensy versions without soldering) i now have more than enough memory but the clock no longer works…
I went back to the matrix clock example and loaded that with the same result (“DS1307 read error! Please check the circuitry.”)…
The teensy 3.2 pinout matches exactly the teensy 3.6 as far as the matrix shield connections go… The only difference is im plugging a 3.6 in instead of a 3.2 into the shield… I have the RTC connected correctly as if it wasnt the teensy 3.2 wouldnt work…
Any ideas would be very much appreciated…
Thanks
Daniel
