My Teensy 3.1 (T3.1) loses serial connection and also non-functional (but recoverable); Could use help tot figure out why.
In this un-responsive mode, it no longer appears connected (under Port) and devices attached to it (2.2" TFT ILI9341) goes blank.
Recovery : (Thanks Paul, picked this up from a previous "Teensy dead thread") Disconnect USB cable, hold Reset button, reconnect USB cable, wait 15sec release USB button; then load "Blinky"; then upload program again (code below)
After recovery, the code works; but would feel much better knowing why the T3.1 went un.responsive.
This behaviour is a recent thing, since I moved the T3.1 from the breadboard to a prototype board.
On the breadboard, the program was stable, and operated indefinitely.
On the breadboard mu connections were: CS=D10, DC=D9; MOSI=D11, MISO=D12, SCK=D13, RESET=Vdd(3.3v), RLED=100ohm from 3.3v
In going to the porto board, I did make a few small change,
CS=D15, DC=D10, others remained the same MOSI=D11, MISO=D12, SCK=D13 RESET=Vdd, RLED=82ohm from 3.3v
HW wise, I have double-checked connections; all seem fine (evidenced by the board working after recovery)
I do not see any component on the T3.1 board, or the 82ohm resistor, or anything on the TFT board getting hot.
Grateful for any thoughts and suggestions..
thanks..

PS. I am relatively new to the Teensy devices, and still learning..
