Re: touch screen

Let me also clarify that this is only for the Teensy 3.6. The NANO is a different story and
there you have to match baud rates.

So, when you have the program's baud rate at 115200 and the Serial monitor at 9600, you get the proper output on the Serial monitor?

If the Teensy always uses 12mbs, but the USB port is set to some other speed, are you saying that the Teensy automatically adjusts to the USB baud rate? Also, there's a difference between communicating with the Arduino IDE using a Teensy baord and the PC at the same baud rate and the Teensy running standalone and using one of its ports. That I can agree with, but I do not think that's true when working with the IDE. All of Dave's questions are relative to compilation processes.

From Teensy pages:
"Unlike a standard Arduino, the Teensy Serial object always communicates at 12 Mbit/sec USB speed. "

So it doesn't seem to matter what you set the baud rate in the program or what is set in
the Serial Monitor!? The Teensy serial ports understand each other....

ok i'll except that.

but puzzle this.? i set the baud rate at the setup to 9600 and forgot to
reset the monitor baud rate and the thing works now when it show 115200.

explain

but i done show the eeprom dump on the monitor?

Ports 0 and 1 are normally the Serial monitor ports for COM when the
board is running your code, but the programming port is something
else. The only thing I can think of is that the DEBUG flag isn't set
at the top of the JackAl.h header file, or there's a mismatch between
your monitor's baud rate and JackAl, which is set to 155200.

for some reason i am having trouble with the serial monitor.? when i
load the program it shows it is using port 1.? but if i watch when
connecting the usb cable it shows that i am using port 5.? but in
either case i get nothing on the serial monitor.

i thought that maybe something was wrong with something in the
computer so i tried using things to load a program into a nano card
and thing worked fine. it was using port 6

anyone have an idea what is happening?
