Hello,

Is there a way to reprogram a Teensy 3.6 with and ESP8266?
Can I trigger the reset pin of the Teensy with one of the gpio of the ESP8266 then send the hex file to the teensy?
Is there a pin to RX/TX common to the USB serial?

Thank you in advance,
Renaud
 
The simple answer is you can only program a Teensy 3.x with USB.

Long answer I believe that some have tried other ways to reprogram, but this required that the Teensy had a program on it, that as part of it, would try to load the new program (over the air) and then save it away... Which might be risky...

I know I have seen a few threads talking about this, like: https://forum.pjrc.com/threads/4316...dates-changes-for-flashing-Teensy-3-5-amp-3-6

Not sure if that was the best thread talking about it, nor how successful people have been.
 
Thank you for reply!
I think I can do it with an Arduino Uno by connecting pin 0 and 1 to the ESP8266. I plan to drive a rgbled matrix (484 led). Not sure the Uno can do the job :(
Is there a simple way to connect the ESP to the USB?
Thx
