Teensy 4.0 Serial monitor with USB RawHID?

[hsweeten]

Is there any way to get the Serial monitor to work when the USB Type is Raw HID?

Thanks

[KurtE]

Yes

The USB Type of RAWHID,

generates two interfaces:
RAWHID

And

the Serial emulator (SEREMU), and the Teensy Serial monitor knows how to talk to SEREMU as well as TyCommander

Hmm.. I tried that but still don't see anything in the Serial Monitor. The title of the window says "TeensyMonitor: Closed".

I still have not figured out how to get the TeensyMonitor to work with RAWHID and the serial emulator.

My connection on the bottom of the Arduino window says:
Teensy 4.0, Raw HID, 600 MHz, Faster, US English on fake serial

When I open the Serial Monitor the top of the window says:
TeensyMonitor: Closed

Is there something I need to add to my program to get it to work?

Thanks,
Hartley

Again Hard to know what exactly what is going on, with your setup.
I am running Windows 10 Arduino 1.8.19 Teensyduino 57 beta 3...

But I just loaded the basic example under USB type rawhid, and configured for RAWHID Teensy 4
And I ran the EXE for demo RAWHID from: https://www.pjrc.com/teensy/rawhid.html
After the program uploaded, I made sure that I had the proper Serial port selected...
And:


Note: I also needed to make sure I was not running TyCommander at the time as it might have connected up to the port.

As it it too knows how to talk SEREMU...

Weird... I just can't get it to work.

I did download the TyCommander repo and built it for my Linux machine. It does see both the RadHID and Seremu interfaces:



But I get nothing in the Serial output:



I did make sure that the Serial interface is started in my program:

void setup() {
    Serial.begin(9600);

And I do have a number of messages being sent to the Serial interface:

    TSPoint p = getRotatedPoint();
    if (ts.isTouching()) {
        Serial.print("T: ");
        Serial.print(p.x);
        Serial.print(",");
        Serial.print(p.y);
        Serial.print(" Z: ");
        Serial.println(p.z);

But nothing is ever received.

Maybe an issue with Arduino 1.8.13 and Teensyduino 1.53?

[KurtE]

Some Hints: Linux... Which? Something like Ubuntu? Which version?
And you are running 1.8.13 and 1.53...

Maybe time to boot up my Ubuntu 22.04 setup.

[KurtE]

Again it appears to work on my Ubuntu 22.04 machine.


Note, I am running TyCommander here 0.9.0-107...
Which I built from current sources

Edit oops, the picture before was without focus...

I finally got it to work. Not sure what fixed it or what I was doing wrong before but now it works.

Thanks for putting up with my confusion.

Now I can try to figure out why I sometimes get odd touch results with the Teensy 4.0 board.

The TouchScreen library works fine with the Teensy 3.2 But with the Teensy 4.0 I occasionally get garbage results when I hold my finger on the touchscreen.
