Auto scroll teensy 3.2

[santoslao]

hello i'm ours in the programming and here in the community.

I am easy to understand, I would like to know, how can I program in a tiny 3.2 an automatic scroll by time? Would anyone have this code ready so that I could start my project?

Example: I need to scroll down one page every 30 seconds, as if I were doing this with a normal mouse.

one page every 30 seconds? why not just do PAGE DOWN keycode?

You could use something like this:

void setup() {
}

void loop() {
  Mouse.scroll(20);
  delay(30000);
}

Don't forget to set Tools > USB Type to one of the options including Mouse, so Teensy becomes a USB mouse after you upload the code.

I'm new to programming with teensy, but if you suggested page down can you pass me the code? I confess that I really don't know how to do it. I want to learn more from colleagues on the forum.

it uses keyboard keystrokes, look for KEY_PAGE_DOWN

Keyboard.press(KEY_PAGE_DOWN);
Keyboard.release(KEY_PAGE_DOWN);

for my project it doesn't work with page down, only with scroll. But I appreciate the help

Well then, the good news is you can use Mouse.scroll(num); (as mentioned in msg #3)

The "num" input is a signed integer for how many clicks of the scroll wheel Teensy transmits to your PC.
