Hallo everyone,
I have a good knowledge about Arduino (namely the Arduino Pro Mini - 3.3 V), now I'm approaching with a lot of curiosity to the Teensy world.
Talking about the Arduino Pro Mini, the two serial pins used to upload a new sketch (by using an FTDI device) are actually the same TX and RX pins located on the side of the board (namely pins #0 and #1).
This means that if you have a powered device talking to Arduino with the serial lines then you have to physically disconnect it (or power it off) before uploading the new sketch.
Here my question:
is the micro USB connector on the Teensy 3.2 totally independent from the pins of the three serial ports available? In other words, it is possible to upload a new sketch on Teensy 3.2 without disconnecting any powered device wired to a serial port?
