Hi,
I'm interested in using the RTC functionality that is (apparently) part of the Teensy 3.6. First, is there any documentation that speaks to how to do this? Is there any "Getting Started with RTC on the Teensy" kind of document or link?
If not, my searches on this forum seem to suggest that I just need to add a coin cell to the VBat terminal in the central area of the Teensy 3.6 board. Is this really all that I need to do? That's pretty easy!
My question is whether I'm only limited to a coin cell. What voltages will this pin tolerate? Currently, I've re-wired my Teensy to be powered by an Adafruit LiPo (https://www.adafruit.com/product/1578). I could easily shoot a wire over to the RTC Vbat pin as well. But, the voltage of this battery ranges up to 4.2V. Could 4.2V damage the Teensy?
Clearly, I'm a total newbie when it comes to RTC. I would appreciate any guidance that you can provide.
Thanks,
Chip
